PROBLEM

POSSIBLE CAUSE(S)

CORRECTIVE ACTION

DRIP FROM TEMPERATURE &
PRESSURE RELIEF VALVE
(page 24)

1. Excessive water pressure

2. Add or service a thermal expansion

tank.

3. Non-functioning Temperature &

Pressure Relief Valve

4. Debris under valve seat.

1. Check water supply inlet pressure. If higher

than 80 PSIG, install a pressure reducing

valve (50-60 PSIG is the recommended pres-

sure.)

2. See “Water Pressure Increase Caused by Ther-

mal Expansion” section on page 7.

3. Replace the Temperature & PressureRelief

Valve

4. See “Drips from T&P Relief Valve Discharge

Pipe” section on page 24.
