Purpose
-
Water heaters operate at high temperatures and high pressures. A pressure release valve is a designed to allow pressure to escape if it becomes too high.
Safety
-
If a pressure release valve is not functioning properly and cannot relieve tank pressure, safety can become an issue. It is possible for a malfunctioning water tank to over pressurize and explode.

Water
-
A properly functioning hot water tank will occasionally release water through a short pipe connected to the release valve. This can cause water to collect near the unit, but does not necessarily indicate any malfunction.
Maintenance
-
To prevent possible problems, hot water heater tanks should be inspected by a professional. The release valve can be tested and cleaned to ensure proper function.
Replacement
-
Defective release valves can be replaced individually, and are available at home supply stores. Parts should not be replaced without consulting the unit manual or a professional.
