Home Purchase Due Diligence

Due Diligence: Is it only for big corporate acquisitions? | Home Inspections Colts Neck NJ

 

Due diligence is the investigation or exercise of care that a reasonable business or person is normally expected to take before entering into an agreement or contract with another party or an act with a certain standard of care.

It can be a legal obligation, but the term will more commonly apply to voluntary investigations. A common example of due diligence in various industries is the process through which a potential acquirer evaluates a target company or its assets for an acquisition.[1] The theory behind due diligence holds that performing this type of investigation contributes significantly to informed decision making by enhancing the amount and quality of information available to decision makers and by ensuring that this information is systematically used to deliberate on the decision at hand and all its costs, benefits, and risks.”   Due diligence – Wikipedia

 

Like any purchase of significance due diligence is important and you probably don’t realize it but you already do it to a much, much simpler degree. Do you compare performance information and mileage for a new vehicle you may be considering buying?  That’s due diligence.  Do you compare school districts or the time to commute to and from work for the new home you’re thinking of buying?  That’ due diligence. And of course, the purpose of this piece is to make sure that you recognize that a home inspection is a critical aspect of your home purchase due diligence.

By law, the home inspection is a non-destructive inspection of various systems and components of the home. Exterior, roof, electrical elements, baths, etc. We at Regal Home Inspections, LLC, of course, follow the law to the letter of the law and we strive to surpass the bare minimum as required. For example, the law requires we check 1 outlet per room and one window per room.  If accessible, we usually check as many as we can, not the minimum. The purpose of this piece however it not to review the home inspection due diligence that Regal Home Inspections, LLC does but what you may want to consider (Or we may recommend) beyond the scope of the NJ home inspection standards of practice.  To that point, I am also licensed by the NJ DEP (License # 59628B) to inspect for wood destroying insects and prepare the industry recognized, “Termite Report”.  Both my son & business associate and I are also licensed to conduct radon measurements (NJ DEP Radon Measurement Technicians) MET14070 and MET13186 respectively.

You may not realize it but you’re already paying for elements that fall under due diligence. The title search that you’re doing.  The appraisal that the mortgage company may require.  The appraisal is more due diligence for the lender than it is for you, the buyer.  While I’m talking about the lender, when they verify your income and credit rating, that’s part of the business due diligence of them making the loan to you.

There are things beyond those that we do as home inspectors (Inspection, termite and radon) that we sometimes recommend and sometimes urge you get as part of your home purchase due diligence. As of now we don’t do them but we can refer you to good companies that do.

  • An oil tank sweep. Oil tanks were common for many years. Going back decades, natural gas was not as prevalent as it is today.  In the past, houses may have been heated with electric or oil if natural gas wasn’t available. There are many houses still heated with electricity and there are still some with oil.  However, it’s the ones that no longer have oil but did that we’re concerned with. What do the sellers know and is it accurate?  Years ago it was OK to have an old oil tank cleaned and abandoned in place. However, as I’ve heard, insurance companies will charge a higher premium if the property has an abandoned oil tank. If the property you’re considering buying as an old tank decommissioned and left in the ground, INSIST, that it be removed by the seller. You absolutely do not want to purchase the risk and liability of an underground oil tank. An oil tank sweep is relatively inexpensive and worth every penny. Usually the cost is between $275 and $450 depending on the size of the property.

  • Sewer scope analysis. Information suggests that up to 80% of the waste pipes from the house to the sewer connection have some type of issue. It could be roots that have grown into the waste pipe. Bellies where there’s a dip in the pipe that can collect waste and hinder good drainage. Breaks in the pipe, cracks or holes. Often, a family of 4 or 5 is buying a house from an original owner where one person has been living in the home for years. Years earlier there was a family but as the children grew up and moved out, eventually, like me and my wife, there are two people living in the home.  The water use for an older couple or a single, older occupant is very, very different than for a family of 3, 4 5 or more. The waste pipe from the house may be able to handle the one or two loads of laundry a week and a few showers a week for the older occupants but when the young family moves in and there are multiple showers and baths a day and multiple loads of laundry a day, etc. The corroded waste pipe is no longer able to handle the waste water volume of the young family as it could for the older couple. A video, sewer scope analysis of the sewer pipe is worth it’s weight in gold.

Financially, for both the oil tank and sewer scope, you’re talking about $300 for each to be sure vs. many thousands of dollars to repair.  Is it 10 to 1?  $300 vs. $3000?  No, it could be more like 30 to 1 or 50 to 1.  That’s $9000 to repair or $15,000 to repair and quite possibly more.

 

In conclusion, think of your home purchase as a business acquisition and your duty is to perform all of the reasonable due diligence needed. The home inspection is #1. DO NOT WAIVE YOUR HOME INSPECTION!  #2 Think about some other, important services: Radon test, termite inspection, oil tank sweep, sewer scope analysis, lead paint, mold and pools.  Anything that’s important to you should be part of your home purchase due diligence.

Do Not Waive Your Home Inspection. Part 1.

Electrical Issues…A Great Reason NOT to Waive your right for a home inspection.

July 27, 2021

We’re in the COVID Era.  Many people are in a panic, including, for the first time, panicking about where they live.  My wife and I came to New Jersey, from Staten Island, NY in 1987.  We, like many New Yorkers, sought a better life and standard of living for our young and expanding family.  And, without a shadow of a doubt, we achieved a better life in the Garden State.

As a licensed home inspector in Monmouth County, NJ I’ve done many inspections for people moving to NJ for a better life.  NJ’s beaches and rural, suburban areas were a welcome change and attraction for people moving from Staten Island, Brooklyn and occasionally Queens. At one time the cost of living in NJ was an attraction too but unfortunately that may no longer be the case but that’s not important when compared to the other, quality of life issues.

Covid has been the catalyst for change in many, many ways. As it relates to the real estate business, Covid is pushing people to NJ. To some degree people are still coming to NJ for a better quality of life but 2020 has given New Yorkers other reasons to flee the Empire State and the Big Apple; Congestion, crime, unbridled riots the summer of 2020 and more. To some degree the real estate industry in NJ has benefited. I heard that Connecticut is also a welcome alternative to New York.

This all means that the competition for buyers is tough. Many buyers and too little inventory.  Supply and demand. What gives? Bid prices go up and sellers put stipulations that only structural or environmental inspection will be permitted. What? For buyers that’s a bad proposition.  You could be buying a money pit or a safety hazard.

Here are some examples of egregious electrical issues recently found that you would have no knowledge of if you gave up your right for a FULL inspection.  One area that a run of the mill DIY homeowner must never do is electrical work!  It could kill if not done properly, start a fire and worse. The examples shown are, in my opinion, so bad that there’s no way they were done by a licensed electrician or an apprentice working under the guidance of a licensed electrician. Items 1 and 2 are from one house inspected the week of July 19, 2021. Items 3 and 4 are from a house inspected the week of July 12, 2021.

  • A sub panel that’s mis-wired.  Neutrals and grounds are together on 2 different bars.  One set, on the top right is wrong because the bar is, by design, electrically isolated from the metal box (Also part of the electrical ground). So the ground wires are not really grounded.  “No big deal” you say?  Wrong, it is a big deal. If one of the hot wires short circuits it will want to go to the ground wire and to an earth ground. But due to the way it’s wired, there is no metallic path to an earth ground. The electricity from the short circuit will energize all of the other wires in the house and potentially electrocute someone or start a fire.
  • The same panel’s ground bar (Bottom left) also has neutrals wired to it. The grounds are grounded but so are the neutrals.

    Grounds and neutrals on the same bar. The problem is that it’s not grounded.

    home inspector colts neck nj
    Neutrals are also part of the ground.
  • At another house there’s a 20amp circuit breaker with a 14 gauge wire. That’s definitely a safety issue. If you don’t believe me try Googling, “Can a 14 gauge wire be connected to a 20amp circuit breaker?”  The 1st response is, “You can not use 14 AWG anywhere on a circuit that has a 20A breaker.”  For me it’s case closed.
  • At Regal Home Inspections, LLC we use combustible gas detectors and check the natural gas valves and couplings around the water heater, furnace or boiler and dryer when accessible. Yes, we found a gas leak. Do you want to move into a house with a gas leak? Of course that’s rhetorical question, of course you don’t. But if you give up your right to an inspection, that’s what you may end up doing!
  • home inspections monmouth county nj
    Gas leak detected.

Don’t give up your right to a full home inspection.  If you plan on renovating the bathrooms and kitchen, fine, exclude them from your inspection and maybe the seller will be OK with that.  But do not give away your right to identify Material Defects that effect the safety or habitability of the house.

P Traps and S Traps. What Letter is Your Sink’s Trap?

Plumbing – What Letter is Your Sink’s Trap?

By Frank J. Delle Donne, Licensed Home Inspector

October 24, 2014

For most people, purchasing a house is the largest purchase they have thus far made. Help ensure that you, “Buy with confidence. Sell with pride” ® by using Regal Home Inspections, LLC.

Introduction

Inspectors are required to look high and low. At the obvious and the subtle. In NJ we are required to follow the American Society of Home Inspectors (ASHI) Standard of Practice. Within the plumbing section we are required to describe the systems and components that are part of the house’s plumbing. This includes the supply pipe material, drain and waste pipe material, location of the main shut off and more. This article will look specifically at the drainage pipes and more to the point, the trap, under the sink.

Drain Pipe System and the Trap

When water exists any sink, kitchen, bathroom, laundry, bar, etc. it makes its way toward the sewer or septic system. The obvious purpose of the drain pipe system is to route the water, without leaking, out of the house. Within the drain pipe system is the TRAP. This is the little loop directly below the sink usually seen from inside the cabinet below.   While a secondary benefit of the trap may be to trap your wedding ring when it falls off when you are doing the dishes but in fact, the primary purpose of the trap is a safety device.

The Trap as a Safety Device

Sewage gasses are created as the waste matter decomposes. Just like a garbage dump generates methane gas that has to be vented, the sewer or septic system creates methane gas and unless it is kept from rising through the drain and waste plumbing, it will enter the house. Methane gas is flammable so therefore it is dangerous.

The trap facilitates the creation and maintains a water-plug that prevents these unwanted gasses from entering the house. That is the absolute primary purpose of the trap, to hold the water plug. If it also saves your marriage, that’s a side benefit.

The trap works because there is usually a vent pipe next to it. The vent pipes are part of the piping systems that you can often see penetrating the roof of a house. The open vent above the roof helps water drain properly and helps create the water trap.

What Type of Trap Do I Have?

Most sinks have a “P” trap below it and then, in most applications, behind the wall is a vertical vent pipe that goes up through the roof as well as the pipe that goes down that carries the water.   The typical P trap looks like a P if you envision the flat section of the letter P horizontally. Take the letter P and turn it 90 degrees clockwise. The P trap in conjunction with the vent ensures that enough water will remain behind to ensure the water plug does its job.

Occasionally the plumbing under a sink is an “S” trap.   This is when the drain from the sink comes down a few inches, loops back up then loops back down. See the accompanying photos. P traps are good. S traps are bad.

DSCF7440
Example of a P trap.
DSCF7921
Example of an S trap

 

 

Why are S Traps Bad and how can it be fixed?

S traps are bad because they present the potential for water from the sink creating a siphon and as the water empties, once the water starts flowing, without a vent, the last few inches of water don’t know that they have to be the water plug and gravity and the force of the emptying water carries all of the water out of the S trap. There is no water plug and gasses can enter the house. If you’re merely running the faucet a water plug will probably be maintained. However if you ever fill the sink and pull the stopper, there’s a lot of force and a siphon can be created so that the last bit of water follows the water molecules in front and nature’s course is for every drop of water to follow the one before it and the last ones never get the message to stop and become the water plug.

Plumbers can now use Air Admittance Valves (AAV) where an S trap exists. This can be an inexpensive fix to a potentially harmful condition. The AAV is a mechanical, one way valve that can let air in behind the water to ensure that the water plug remains and when there isn’t water draining, it closes to prevent gasses from entering the house.

Conclusion

Regular P traps are most common and provide a valuable function. S traps are an issue on a home inspection but rest assured that there is a fix that shouldn’t deter you from buying the home you are considering.

Findings of a Home Inspector

By Frank J. Delle Donne, Licensed Home Inspector

July 11, 2014

For most people, purchasing a house is the largest purchase they have thus far made. Help ensure that you, “Buy with confidence. Sell with pride” ® by using Regal Home Inspections, LLC.

Please leave a review of this article or of our services.   Click Here and then click on, “Write a Review”.

Reading this article will not guarantee that you will sell your home. It offers observations of issues found in homes both new and old. However, older homes usually contain more issues. 

If you are planning to sell your home and would like to have a Seller’s Inspection conducted please call Regal Home Inspections, LLC. We can perform a thorough inspection and make recommendations that should help any buyer feel more comfortable in making an offer.   We can perform a New Jersey Administrative Code (NJAC) compliant home inspection. We can conduct a radon test and have your house professionally inspected for termites and Wood Destroying Insects and Wood Destroying Organisms (WDI/WDO). We can also conduct pool inspections. If issues are found we can help facilitate additional levels of expertise. All in an attempt so that your home, a small cape cod or a country estate, will be better prepared for the eventual buyer’s inspection and closing.

Introduction

In the first part of this two part series I tried to introduce the reader to some not-so-obvious maintenance issues that I have found during my home inspections. The reason they are important is because they are safety related and some are objectively deemed to be Material (aka Major) Defects. This article looks at a few others. The goal here is that possibly sellers will read this, consider their home and either perform a more thorough inspection on their own or, better yet, hire Regal Home Inspections, LLC to perform a Seller’s Inspection so that when it comes time for the buyer’s inspector to come through, many of the issues may have been addressed already. There are two ways that a seller can benefit from a Seller’s Inspection performed by Regal Home Inspections, LLC. First, the seller can use the findings to make corrections and/or repairs. Second, the seller can always include those items found in the Seller’s Inspection in the Seller’s Disclosure. I find that home sales hit snags when things are found by the buyer’s inspector that weren’t previously known by the seller or the seller knew but was hoping the inspector wouldn’t find. Quite the roll of the dice for all parties.

Brief Review (This section is repeated from the initial article)

The NJAC has many requirements of an inspector. However, when it comes to the actual inspection and the reporting there are a few key points. The NJAC follows the Standards of Practice of the American Society of Home Inspectors (ASHI). When it comes to the inspection, the inspector is required by law to DESCRIBE specific systems and components of the house; Plumbing, electrical, exterior, etc. The inspector is required to IDENTIFY any Material (aka Major) Defects; Findings that effect the habitability, safety or value of the home (in very simplified terms here). And the inspector is required to PREPARE a written report memorializing the previously mentioned elements.

What the inspector is not doing is determining if the curtains match the rug. If the choice of siding materials matches or clashes with the general theme of the other houses. We are looking for very specific things that are not otherwise apparent to the buyer or the seller and for this reason, it’s a very good idea for the seller to be as prepared as best as possible. You painted the walls so they look fresh, right? You had the grass fertilized and the bushes trimmed so the yard has curb appeal, right? Maybe you’ve even put some chocolate chip cookies in the oven to make the house smell good for that open house?

Preparing Your House

Does anybody decide on a Monday, out of the clear blue, that they are going to list and try to sell their home that day? Isn’t it more reasonable that people know in advance that they will be selling their home? It may not be known years in advance but a month, maybe two at least. “Honey, maybe we should plan on selling our home when we retire next year?” Or perhaps, “I just got offered a new job at work but it requires a relocation. The company wants me to move to California in 2 months.” My wife and I have been in our current home for almost 22 years with no plans to leave…yet. However, when we moved into our previous home in April, 1987, we knew that in the summer of 1991 (over 4 years later) we would be moving again. We used the summer when our oldest child would be between kindergarten and 1st grade as the target. I am not kidding when I say that we knew at the house closing in 1987 that between the end of June and early September, 1991, we’d be making another move.

Literally, the day before my son started 1st grade on September 5, 1991, we moved into our current home. That 1st grader is now 29 years old!

Sure there are exceptions. Parents pass away suddenly and the home has to be sold as part of an estate is one example and there are others. The point is that in the majority of situations planning can occur and fixing inspection related issues should be high on the priority list. Especially for estate sales!

According to the Consumer Product Safety Commission, Ground Fault Circuit Interrupt (GFCI) outlets are currently required in any outdoor outlet, kitchens, bathrooms, laundry rooms, garages, unfinished basements and elsewhere. A home inspector must look for and test GFCI outlets. GFCI outlets (and GFCI protected circuits) protect people from stray electrical current that they may inadvertently come in contact with. Electricity wants to follow the path of least resistance to ground. When people are struck by lightning, they accidentally become the path of least resistance to ground for that lightning bolt. If there is a damaged electrical circuit in the kitchen, bath or elsewhere, a person may accidentally become the path of least resistance to ground. A GFCI outlet or circuit can detect that unintentional path and in a tiny fraction of a second, the GFCI shuts the electricity off.

When I am inspecting a house I provide the client with information that shows, for example, that GFCI outlets haven’t been required in kitchens since 1987.   I inspected a house last week that was built in 1977. Before I went inside the house I provided information to the client and stated, we may not find GFCI in the kitchen…and we didn’t. It’s a Safety item on the report.   This sale may not go through because the GFCI are one item on a not too long list of things that need to be fixed. It’s an estate sale with, “who gives a damn” sellers that just want their money.

Does your house have a door between the attached garage and the living area? If it does, is the garage door solid core or metal? Is it fire-rated? Does the garage door have a mechanism (spring loaded hinges or other device) that AUTOMATICALLY closes and latches the door between the garage and living area? Spring loaded hinges cost about $10 each at Home Depot or Lowes. Don’t have a fire rated door or it doesn’t automatically close and latch? It’s a Material Defect related to SAFETY.

How close does the soil get to your siding? In a wood framed house you have the foundation wall and then the wood frame sits on top of that. The siding, let’s assume vinyl, covers the wood framing and exterior wood sheathing. It’s not a Material Defect or a Safety item but the inspector will recommend that there is at least 6 inches of space between the top of the soil and the bottom of the siding and wood framing. Does a buyer want to close on a new house and then spend the next couple of weekends digging and raking the dirt away from the house? I’d bet the answer is a resounding, “NO”. If you’re planning to sell, hire a landscaper and pay them some money to re-grade your yard so that you can see 6 inches of concrete foundation between the top of the soil and the siding. Do you know why it’s important? Let me put it to you this way. If the soil comes to the siding and framing, the inspector will tell the buyer that the condition makes it easy (conducive) for termites to go from the soil to the wood. Do you know what the buyer thinks? They think, “if I buy this house I’ll have termites!” All they will remember is, TERMITES! An associated aspect to this is if you are planning to sell, get a termite inspection and treatment. Have the pesticide company give you a certificate and share that with the buyers. Turn a potential negative into a positive.

Conclusion

I have just shared three inspection issues that are A) Relatively easy to fix and B) Can scare the heck out of a buyer and chase them away. Regardless if you are buying or selling a home, it is a significant transaction either way. Buy with confidence and sell with pride by having Regal Home Inspections, LLC conduct your inspection. We look for things that you probably never considered. That’s why we can help you avoid issues and delays in closing when the buyer and seller are of different minds on whom should address inspection item A, B or C. We can help get some of them out of the way for the seller or help the buyer identify issues that may not be obvious.

Regal Home Inspections, LLC starts every inspection with the presentation of a folio of information for the client. That folio includes general information but also includes a written introduction to the inspection. I present an initial overview of the main elements detailed in this article; Laws that govern the inspection process, areas that will be inspected and more. I believe this is unique to the service that Regal Home Inspections, LLC provides.

Plumbing – Part 1 – What Makes up a House’s Plumbing System?

Plumbing:

Part 1 in a Multi Part Series.

By Frank J. Delle Donne, Licensed Home Inspector

January 6, 2014

 About the author.  I am a NJ Licensed Home Inspector.  I am the owner and Senior Inspector at Regal Home Inspections, LLC.  I am a member of the New Jersey Association of Licensed Professional Home Inspectors (NJ-ALPHI) and the National Association of Certified Home Inspectors (NACHI).  The standards used to inspect your home’s systems are in accordance with New Jersey State laws, the American Society of Home Inspectors (ASHI) and NACHI Standards of Practice.  Regal Home Inspections, LLC can also test your house for Indoor Air Quality; Mold and Allergens.  Radon contamination is a big issue with homes in New Jersey.  Many parts of Monmouth County and areas around it are considered “High Radon Potential” by the NJ DEP. We are certified by the NJ DEP to perform Radon Testing.

We can also facilitate testing of septic systems and oil tanks; tank integrity and soil tests below ground.

 

Never perform plumbing work yourself unless you are a licensed plumber.  Nothing in this article suggests that you should attempt to make any repairs yourself.  Any attempt to make plumbing repairs or upgrades can result in significant water damage.  ALWAYS hire a licensed plumber to perform any work.   Poorly performed plumbing work can lead to water damage, ongoing leaks and other, related issues.

Introduction

The plumbing system in a standard home inspection is extensive.  There are many aspects to a house’s plumbing systems, not just the pipes that carry water to the faucets and other appliances that use water.  The typical plumbing system in a home includes the pipes carrying cold and hot water but, not including the water heater as a separate plumbing element there are actually three (3) sets of piping in your home that are included in the plumbing inspection.

Before I get into a conversation about the plumbing systems let me point out that often times the vast majority of the plumbing systems are hidden behind finished walls, under floors and above finished ceilings.  Therefore we can actually see a very small portion of the plumbing and to the best extent possible, we make observations and come to conclusions about the entire system based upon what we can see.  In homes with extensively finished basements the amount of plumbing that is visible may be very, very little.

Plumbing Systems

In very general terms the, “plumbing” in a house consists of at least three sets of pipe, the water service entrance and water meter with its main shut off valve(s) and the water heater(s).  The appliances (sinks, toilets, tubs and showers) are also part of the plumbing system so overall the plumbing system in a house is extensive. And to make matters worse, if any one element has a defect which results in a drip, for example, you could have serious problems.  So let’s take a look at the components that comprise the plumbing in a house.

1) Supply Piping.  In a relatively modern home this is the copper piping.  The copper piping is usually ¾ or ½ inch in diameter.  It starts at the water meter (or pressure tank for a private well house) and carries the water to the isolation valves just before the appliance.  An example of an isolation valve is the valve behind the toilet bowl or under the sink.  In the case of the bowl, as you know, there is one valve as the toilet is served by cold water.  Under your sinks there is, of course, a hot and a cold isolation valve.  The copper pipes may also carry water to a hose bib that provides a convenient water valve outside your home.  These may, or may not have an isolation valve.

The supply piping is unique for a number of reasons but it is the only system that is under pressure.  Typical household water pressure is between 40psi and 60psi.  If your pressure is too low you will not get good water flow.  If it is too high, (at or above 80psi) you may have the potential to burst pipes, valves, gaskets and the like.  If you are concerned about your water pressure being too low, perform the following, simple test.  This may be an indication that your supply piping is in need of maintenance or replacement.

  1. Go to the highest bathroom in your house.  Usually it will be a full bath on the second floor.  If you have a ranch then any full bathroom will do.
  2. Turn on the sink valves and the tub and/or shower.  They should all be fully opened and running.
  3. Then, flush the toilet.  Watch the flow of water from the sink and tub/shower.  If the flow rates at the sink and tub/shower do not diminish, then you have adequate household pressure to operate your plumbing fixtures.  If they all slow down when you flush the bowl, you likely do not have adequate flow.

For a home built in 2014, the supply piping may not be made of metal.  There are a number of plastics used in current construction.  In homes built in the early 1900s and up to about 1940 you might actually find lead in the residential piping.  This should be replaced.   Galvanized steel was also used up to about the 1950s.  Galvanized steel rusts from the inside out and it is prone to becoming clogged inside the pipe from the rust build up.  Also, with this inside-out rusting the thinner areas where the pipe is threaded is  prone to leaking.   Brass may have been used in homes built in the early 1900s as well.

Copper has been in use since the middle 1900s.  It is durable, resistant to corrosion unlike the galvanized steel, and it’s relatively easy to work with. In summary, depending on the age of the home you may find different supply pipe materials, some of which should (must) be replaced.

2) Waste Piping.  The waste piping carries all the waste water and solids from the sink drains, washing machines and toilet bowls outside the house to the sewer system or to a private, septic system.  Modern waste piping is made of economical and easy to install PVC or a similar plastic material.  This is either white or the other forms of plastic piping may be black.  If it is visible, perhaps from an unfinished basement, you will see a series of feeder pipes running vertically into larger horizontal pipes and eventually the larger pipes will exit through the foundation wall in either a basement or perhaps in a crawl space.  This waste piping is not pressurized and for those sections that are not vertical, the slope should be relatively mild; about ¼ inch of slope per foot of horizontal pipe.

In older homes the waste piping may be cast iron.  Much heavier than modern materials and more difficult to handle and install.  There are all manners of interconnection devices so if a home improvement is being done you can remove sections of cast iron and replace it with PVC and they will interconnect very reliably.

3) Vent Piping.  Vent piping is the series of pipes that run (mainly) vertically and allows the waste water to flow properly.  To explain how the vent piping works and why it’s important think for a minute about a soda bottle.  If it’s full and you hold it upside down and then remove the cap the soda will gulp, gulp out and not evenly flow.  If you then poke a hole in the upper part of the inverted bottle the soda will pour out because the hole allows air to enter behind the soda.  The vent piping performs the same basic function as poking a hole in the soda bottle.  The vents allow air to follow the water as the water exits the house.  Without the vent piping the waste water would gulp, gulp, gulp its way out of your home.

The tops of the vent piping can usually be seen along the rear roof line of the home.  The vents penetrate the roof and allows air to flow behind the water.

These plumbing vents should NEVER terminate inside the attic or any living area.  Sewage gasses pass up through the vents and you do not want these gasses getting into the attic or any other living are of the house.  Vents should also not terminate near windows as the gasses could flow back into the house through the open window.  The gas needs to dilute quickly with the outside air and become benign.

So those are the three types of piping; Supply, waste and vent.

The entire plumbing system also consists of the water heater and the fixtures or appliances (sinks, bowls, etc.) that are connected to the supply and waste piping.

Water Heaters

Most water heaters are of the storage tank variety.  A few years ago instant-hot water heaters became popular and only made hot water when it was needed.  Personally, I believe the “instant” hot water is a slight misrepresentation.  The “instant” hot water maker begins to generate hot water as soon as a hot water valve is turned on but it could take a few minutes for the hot water to actually get to the faucet where the person is.  I don’t think that’s instantaneous as the name implies.

True, a tank hot water heater will maintain the desired hot water temperature in the tank whether the hot water is needed or not so this is somewhat inefficient.  The system I have is ideal in my opinion.  True, it is not as energy efficient as the “instant” water heater but in my case energy efficiency is not my primary concern.  And to tell you the truth, the simple convenience of being able to step into the shower 10 seconds after I turn on the water is also, not my primary objective.  In my house our water comes from a private well and the waste goes into a private septic.  If I didn’t have the system I have over the course of 1 year I would have pulled thousands of extra gallons of water from my well and dumped thousands of extra gallons of perfectly clean water down the septic system.  My primary goals are to be as efficient as possible with my water consumption and with my water disposal.  Conservatively I calculate that I have saved well over 12,000 gallons of water in the 6 years that I have had my hot water circulating system.  That’s 12,000+ fewer gallons pumped from the well and 12,000+ fewer gallons unnecessarily  poured into the septic.

A tank water heater with a re-circulating pump and a parallel hot water line is the best system for my needs.  I constantly have hot water circulating though my hot water pipes.  When none of the hot water valves is open the system is closed but constantly circulating hot water.  In the case of the master bath shower, 110 degree water is about 8 feet away from the shower head.  It’s like having a dedicated water heater a few feet away from every hot water valve.  In contrast, if I didn’t have the re-circulating pump the hot water from the tank would have to travel over 80 feet from the tank to the shower head.

So in this case, I am saving many gallons of water every day.  Yes it is costing me a little more in energy (natural gas) to keep the water hot but for my application, the system I have is what I need.

If you are interested in a hot water circulating pump for your house call Regal Home Inspections, LLC or email and I’ll put you in touch with the local plumber that installed mine.

When inspecting a home I look for a number of things associated with the water heater.  Not all are mentioned here but on an inspection the heater is thoroughly checked.   Let’s start with the make and serial number and capacity of the tank.  The first two data points will help indicate the year of manufacture.  If the heater is very old the buyer will be informed that the water heater may be nearing the end of its useful service life.

Where the pipes enter the tank on the top surface there is usually stamped into the metal the words, “Hot” and “Cold”.  Let’s make sure the heater is installed correctly!

The water heater may be electric but if it’s natural gas or oil I will check some other things including the exhaust vent piping and the burner area.

Of course I am looking for rust on the tank and indications that it may be leaking.   These are a few of the things that I look for on the water heating appliance within the overall household plumbing system.

Finally there are the appliances that use water that are considered part of the plumbing system.  The sinks, toilets, tubs, showers, clothes washing machine and dishwasher are parts of the plumbing system too.  Details on what I am looking for on these appliances will be covered in a future article.

If you are planning to sell your home, give Regal Home Inspections a call and hire us to perform a pre-listing inspection.  Here’s the logic.  If you allow Regal Home Inspections to perform an inspection before you list you can take care of some of the things up front.  You can use the inspection findings to make a list for the seller’s disclosure. More importantly, you can set the price with this knowledge.  Think about it…if you ignore the issues now, then when it comes time to execute the contract, the buyer’s home inspector will find these problems.  Then you are either negotiating away premium dollars to appease the buyer or you’re hiring an electrician (or a plumber, etc.) at the last minute to make corrections and that will cost you top dollar as well.  Deal with the issues you can and disclose the other issues.  That’s why at Regal Home Inspections we say, “Buy with confidence.  Sell with Pride.”
