What to do if Santon Premier Plus 120 Water Heater discharges from T&P Relief Valve?
- JJames MoranAug 1, 2025
If your Santon Water Heater is discharging from the T&P Relief Valve, it could be due to thermal control failure, and the water will be very hot. Switch off power to immersion heater(s) and/or shut down the boiler. Do not turn off the water supply. After the discharge stops, check all thermal controls, and replace them if faulty.
