Whirlpool Temperature and Pressure Relief Discharge

T&P relief valve discharging water periodically

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Excessive system pressure, thermal expansion without expansion tank, faulty T&P valve, overheating water

Safety first: Do not cap or plug the T&P discharge. Turn OFF power or gas if water is extremely hot.

Checks:

Measure static water pressure; if above 80 psi, install or service a pressure-reducing valve and expansion tank.
Verify water temperature is not above setpoint; check thermostats or gas control.
If pressure and temperature are normal but valve still drips, replace the T&P valve with the correct rating.
