It is possible for the valve to release a little water through the drain line during each heating period. This occurs as the water is heated and expands by approximately 1/50 of its volume.
REGULAR CARE 10 TEMPERATURE LIMITING VALVE A RheemPlus water heater is fitted with a temperature limiting valve at the hot water outlet. The valve is set to deliver water not exceeding 50 ° C. The valve should be checked for performance every twelve months.
