Water Heater Repair in Wishek

The tank is the piece a homeowner notices first, a large insulated cylinder sitting in a utility room, basement, or closet that holds and heats the household's water supply. Attached to it are the pressure relief valve and the drain valve, both mounted on the tank body itself. The relief valve is a safety device that vents if pressure inside builds too high, and the drain valve lets a contractor flush sediment from the bottom.

Running into and out of the tank are the cold supply line and the hot outlet line, which carry water to and from every fixture in the house. On a gas unit, a burner assembly and a thermocouple sit at the base, with a flue running up through the tank to vent combustion gases. On an electric unit, one or two heating elements thread through the tank wall, each paired with a thermostat that tells it when to fire.

The drawing shows the general layout of a water heater system, and a licensed contractor determines which parts and connections apply to the specific unit in your home.
