3 Water Heater Components to Know

PLEASANTON — Besides its tank, a water heater has several functional components and connecting parts. Here are a few important ones to know about:

Water connectors
These deliver water to and from the water heater. The best product for this is a stainless steel flex line, which has a full port valve (meaning nothing constricts the flow of water). Braided lines, on the other hand, have restricted valves and rubber linings that gradually break down and end up in the water. These, along with black hoses (which are also braided), should be avoided.

Flue pipe
This is where natural gas is ventilated from the unit to the outside. If this pipe is broken or has visible gaps, it could potentially leak carbon monoxide into the home or garage, which is extremely hazardous. If your water heater’s flue pipe looks compromised, call a plumber to come out and take a look at it.

Temperature and pressure (T&P) relief valve
This valve acts as a safety device in the event that the water heater overheats or builds up too much pressure. People sometimes like to lift this valve to see water shoot out of the adjacent pipe, but this isn’t a good idea—it should only be used for its intended purpose.
