NAVIEN 30002282E Water Heater Check Valve

The Navien Tankless Water Heaters 30002282E Check Valve is an essential and quite miniature part. This particular type of valve is especially called a check valve because it allows the flow of water in an irreversible direction. A check valve is placed inside the water heater and it only opens to let cold water into the device and heat it. This then shuts tightly to not, allow hot water to flow back into the cold water supply pipe. This ceases mixing between the two or more temperatures of water by maintaining the temperatures of the two separated assuring efficiency in hot and cold water uses.
