These devices, typically located behind the appliance and connected to the water supply lines, control the flow of water to the washer. They consist of a valve body, a handle or lever, and an internal mechanism that either allows or blocks water passage. Two are usually present, one for hot water and one for cold.
Controlling water flow to the appliance is crucial for preventing leaks and water damage. In emergencies, such as a burst hose or malfunctioning washer, quickly closing these valves can minimize flooding. Regularly inspecting and exercising these valves can ensure they function correctly when needed, preventing them from seizing up over time. This practice contributes to the longevity of the plumbing system and can prevent costly repairs down the line.
