For the inspection and writing portion of the residential plumbing overview course, I took a picture of the hot and cold water supply lines and stops feeding my kitchen sink. The lines are made of 1/2" PEX piping and are color coded corresponding to the hot and cold lines. While to my knowledge not a listable defect, I believe from use that the lines should have a support brace located near the stops to prevent the sagging that is evident from the picture. There is also a T in the hot line to branch out and supply the dishwasher. All three lines do have indepent stops for servicing of the fixtures.

Most water heater tanks are steel with a thin glass lining to protect the metal from corrosion. Since the lining eventually cracks, tanks have a second line of defense against rust: a long metal anode rod that attracts corrosive elements in the water. When the rod itself becomes so corroded that it can no longer do its job, the tank soon rusts out, leaks and needs replacement.

Temperature/pressure-relief or TPR valves are safety devices installed on water heating appliances, such as boilers and domestic water supply heaters. TPRs are designed to automatically release water in the event that pressure or temperature in the water tank exceeds safe levels. f temperature sensors and safety devices such as TPRs malfunction, water in the system may become superheated. Once the tank ruptures and water is exposed to the atmosphere, it will expand into steam almost instantly and occupy approximately 1,600 times its original volume. This process can propel a heating tank like a rocket through multiple floors, causing personal injury and extensive property damage.

The water heater acts as a heat exchanger using 180 degree water from the boiler and heats the well based domestic water flowing from the well pump feeding plumbing fixtures throughout the house. It is equipped with a TPR valve and a thermostat for water temperature just like a gas fired hot water heater. The heat absorption rate is less than 200,000 btu and the heat transfer medium must be at 30 psi max pressure.
