What Is an Isolation Valve Kit?
An isolation valve kit is an important accessory used during tankless water heater installation. These valves connect to the hot and cold water lines and allow the water heater to be shut off, serviced, flushed, or descaled without turning off water to the entire home.
Isolation valves are especially important for tankless water heaters because regular maintenance helps protect performance and efficiency. Over time, mineral buildup can collect inside the heat exchanger, especially in areas with hard water. Isolation valves make it much easier for a plumber or homeowner to flush the system and help extend the life of the unit.
