Common Water Issue in BC
Water Heater Pressure Relief Valve Leaking — T&P Discharge
A leaking temperature and pressure (T&P) relief valve indicates excessive pressure or temperature in the water heater. BC homeowners should address this promptly as it is a safety concern.
Possible Causes
- •Water pressure exceeding valve rating (typically 150 psi)
- •Thermal expansion without expansion tank
- •Water heater temperature set too high causing valve to open
- •Failed or worn T&P valve seat
- •Debris preventing valve from sealing completely
Recommended Steps
- 1Check water pressure with gauge — install PRV if over 80 psi
- 2Check if thermal expansion tank is installed and pressurized
- 3Test T&P valve manually by lifting lever briefly — water should stop when released
- 4If valve continues to drip, it likely needs replacement
- 5T&P valve issues are safety concerns — call professional if uncertain
