Replace your hot water duo valve

Is your duo valve leaking? A duo valve or non-return valve controls cold water flowing into a storage water heater and prevents hot water from flowing out of the heater into the cold water supply. A worn out duo valve will often leak from the tap spindle. When this happens, you know that your duo valve is due a replacement.

Having the duo valve in top condition is important for at least two reasons. One, it prevents water loss through leaking. Two, a properly working duo valve prevents hot water from escaping into your cold water pipes.
