Call-Back Visit – Boiler Pressure Relief Valve Returned to assess continued leaking from the boiler's pressure relief valve after recent expansion tank replacement. System is now operating at 20 psi (previously exceeding 30 psi), but the 30 psi pressure relief valve is still discharging intermittently. Tapped on the valve to temporarily stop the leak. Placed a dog bowl under the outlet as a precaution. Recommendation: Advised customer to monitor the bowl for any new signs of leakage. If water collects in the bowl again, the 30 psi pressure relief valve will need to be replaced. If no further leakage occurs, the valve can be inspected and addressed during scheduled annual maintenance in the fall.
