Residential Plumbing Overview for Inspectors Course

This a picture of a circulating pump on top of my hot water tank. Apparently there was a leak that caused this calcium build up. It is a private well water source.

In summary, residential fire sprinklers are a valuable, cost-effective safety addition to any home, although they require periodic maintenance.

Here is a p trap that is proper working order. I also checked the joints to ensure there was no leaks.

For the additional reading I chose hard water due to the fact that it can be hard on the water equipment in a home. It was a great read.

The attached photos show a dryer vent discharging directly into the crawlspace.

I read the article on dryer vent safety. It revealed the dangers and hazards associated with dryer vents.

The dryer vent attached behind the dryer is crushed and impeding on the flow of the dryer air exhaust. This is a fire hazard and needs to be corrected before the dryer is used.

this image shows a drain system that is anything but correct. The white pipe at a 45 deg. goes to a hole located at the base of the foundation. The water from shower and wash mach routes through this pipe and goes to I presume an old underground coal mine. The water from the kitchen takes the same route. A few years ago public sewer was installed but the toilet is the only outlet that feeds the 4 in. pipe. It appears that the pipes on the left were at one time connected as well as the pipe coming from overhead. When this house was built around 1939 the septic system was designed and built by the owner as was common. Every system was different but they functioned. My guess is the septic system at one time had problems so modifications were made. “whatever it takes to make it work” was the mentality.

I inspected the plumbing of a house that I knew would be interesting. Sure enough. The drains lead to the public sewer system as well as an old underground coal mine. The supply lines have been added to and repaired many times over the years. Supports were missing and numerous other deficiencies were found. Upon talking to the owner he just grinned and said it’s been like this for years - it’ll be ok

Good course.

This is the water main service entrance. It has the tag #1 for your reference if needed, labeled on the back. The valve is old and should only be used in emergencies.

In summary of the plumbing system. The water main service entrance is in the 1st floor closet under the stairs labeled #1. The fuel main service entrance is in the same room labeled #2. The boiler is a Weil-McLain oil burner. The boiler is at or past it’s serviceable life. The radiant heat tubing is original to the house and is embedded in the slab. Most houses with this type of construction in this area built around the same time have not remained functional this long. Consult a heating specialist. to be continued

Here is a picture of a dryer vent. The vent is missing a hood. There should be a hood to prevent rodents and water from entering the home, and it should include a damper that remains closed while venting is not in use. Also, the opening for the dryer vent is being used to route Television cabling into the dwelling.

Plumbing Inspection Check List:

-I inspected the main water supply shut-off valve.
-The main fuel supply was not inspected, because it was Not Present
-I inspected the water heating equipment, including the energy source, temperature/pressure-relief (TPR) valves.
-I inspected the interior water supply, including all fixtures and faucets, by running the water.
-I inspected all toilets for proper operation by flushing.
-I inspected all sinks, tubs and showers for functional drainage.

  • The drain, waste and vent system was not inspected, because it was inaccessible.
    -The drainage sump pumps with accessible floats were not inspected, because they were not present.
    -Based upon observed evidence, the water supply is public.
    -The location of the main water supply shut-off valve is located 5 feet east of the drive way, and 3 feet north of the sidewalk in front of the house.
    -I saw evidence of mechanical drain stops and over-flow drain cover that were missing or did not operate or installed in the tub. Correction is needed. Picture attached.

Over all, the plumbing course was good. For the additional article, I read about dryer vents. The dryer vent is a place you’ll often find safety issues. Length, type of material, and termination. Termination is usually a source of concern and should not be over looked. I personally know two people who have had fires start in the home related to dryer venting issues. Luckily, there was no major loss in both cases.

This is an image of a 40 gal. Bradford White electric water heater. You can see the TPR valve exiting the top of the tank, as it should, and you can also see the expansion tank which is necessary because of the check valve located on the service line.

Good morning inspector’s all, this water heater shelf is both hanging at the front right corner, and is quite rusty.
Recommend, In need of repair, monitor.

I completed plumbing inspection as required by this course. No leaks throughout inspection were noticed from any fixtures, drains, or toilets. The water is public with shut off supply being on right side of driveway. Home is all ellectric. Hot water heater, TPR valve, and seismic bracing all appear to be in good working condition. Water pressure in home was adequate even when running two fixtures at the same time. Only defects observed were; 1- under kitchen sink a (P Trap BOOT) was used which could potentially be a leak hazzard, 2- Water supply throughout home is Polybutylene which is know in the industry to burst without notice and is a flooding hazzard. Both defects should be replaced by a licensed professional.

For reading assignment I chose (Polybutylene For Inspectors). Reason I chose this is because it’s whats in my home.

Hi, Below are 2 photo’s of my main water supply shutoff ball valve and electronic municipal meter, with cover opened in one pic and closed in the other.
