Water Heater Installation in Colstrip

The tank or unit itself sits in a utility area, basement, or closet and holds the water supply that feeds the taps throughout the house. A contractor sets it on a stable surface, connects it to the cold water supply line coming in, and ties the hot water outlet line going out to the rest of the plumbing.

A pressure relief valve mounts directly on the unit and acts as a safety release if pressure builds beyond a safe point. The flue or exhaust vent runs from the top of the unit up through the wall or ceiling to carry combustion gases out of the house, and the drain line runs from the relief valve down to a floor drain or outside.

The drawing shows a general layout of these components, and a licensed contractor determines exactly what applies to your home's specific configuration.
