why is my boiler leaking water from the bottom
Water leaking from the bottom of your boiler often indicates a failed internal component like the heat exchanger, pump seal, or pressure relief valve.
A leaking heat exchanger is the most serious cause. It usually means the heat exchanger has corroded through and needs replacement — often a costly repair.
A failed pump seal can leak water from around the circulator pump. This is a simpler repair that involves replacing the pump or its seal.
The pressure relief valve may be passing water if pressure is too high. Check your pressure gauge and repressurize if needed.
