Assignment for How to Inspect Water Heater Tanks.
The gas water heater in this photo was working good but had some issues.
There were no earthquake straps installed, there is no catch pan installed, the cover for the burner section was not installed, and the water heater 11 years old so it is at or near the end of its design life.

My Research article was on Water Heater Expansion Tanks
An expansion tank is a metal tank connected to a building’s water system to accommodate fluctuations in the volume of water in the system, these fluctuations occur because water expands in volume as it gets hot and loses volume as it cools. Expanding water volume in a closed system can create dangerously high water pressure. As water is forced into the tank by expansion, it compresses air contained inside of a rubber bladder. Air is used as a cushion because it exerts less force on its container than water, which cannot be compressed. It is Not a Substitute for a Temperature Pressure Relief (TPR) Valve. It is best positioned near the water heater and may be installed vertically, either above or below the horizontal supply pipe, but can also be positioned horizontally. Horizontally-hung tanks will need additional support.

Cool Re: How to Inspect Water Heater Tanks Course

Water heater repair is one of our specialties. This is my first time in this forum. Are there other water heater repair specialists in here? We are in Springfield, MO. Are there any other Missouri plumbers in this forum?

Attached is an image of the water supply for my indirect hot water heater located in my home. Shown are signs of oxidation or chemical reaction at the entrance to the indirect water heater which has led to leaking. This tank will need to be replaced in the near future because its lifespan is limited.

I read the article titled Estimating the Lifespan of a Water Heater
by Nick Gromicko and Barry Fowler

This article raised the question of repairing/maintaining a water heater vs replacing the unit for a new one. Several factors can go into this decision. An interesting concept was to estimate the yearly cost in maintaining the water heater vs the cost of a new water heater. If the yearly cost of maintaining a water heater is greater than 10% of the cost of buying a new unit than maybe its time to replace the heater rather than repair. Labor costs should be included in this estimate. When replacing the heater it is important to buy quality. A good measure of quality in a water heater can be determined by the length of the warranty.

This water heater appears serviceable and operational. It is properly rated for a mobile home. Has proper wiring, no leaks visible, TPR is installed with drain line to the exterior. It also has the appropriate ventilation necessary.

I chose to read about expansion tanks, and to get a better understanding of their purpose and importance. To include; requirements depending on the area, valves, discharge, water temperature and much more.

In this photo I'm showing a oil fired circulating furnace. This unit is equipped with a heat coil to heat the homes hot potable water supply. If you look closely at the copper piping coming in and out of the heat coil you will see that the necessary mixing valve is present. Also looking up above the unit you will see the system is equipped with a pressure expansion tank.

The water heater inspected appeared to have the safety features properly installed. The seismic strap for a small water heater of this size appeared firmly mounted to the wall, although the drywall was a visual impairment to any confirmation that the mounting screws went into a stud. The TPR valve was connected to copper flex tube that was then piped to the exterior of the building. The mounting deck also appeared to be firmly constructed.

Making the topic of this course eventually obsolete is the tankless water heater. It is likely that as soon as the upfront costs of purchasing and installing a tankless water heater become cheaper, it will be found by inspectors in more and more houses. Tankless water heaters are more energy efficient, take up less space and are more hygienic.

" Hot Water Recirculating Systems "

Recirculating hot water systems are set up in a couple different configurations and are used to get hot water to the source called upon in a quicker amount of time.These systems can be installed in new homes as well as added to existing homes. They can arguably save as well as waste energy depending on how they are used and not used. In some states rebates are offered to help promote homeowners and builders to install the systems. The systems are generally easily available to purchase and should be only around a few hundred bucks.When these systems are in a home being inspected the inspector should be looking for signs of leaks , checking valves, and possibly having to check a sensor that allows water flow as some systems have them.

The pressure relief drain line has been reduced in size. Although commonly found, the pressure relief line should not be reduced- suggest replacing with a 3/4 line.

In the library I found an article on chart water heater checking chart. I found this very helpful in helping me give my clients accurate information on their water heater. I've also found a website that has an app that I can check the year on HVAC and water heaters. www.buildingcenter.org
