Potterton Combi Losing Pressure


I have a combi boiler that keeps losing pressure and the overflow is leaking, every 2 hours or I have to keep topping it up so that I have some warmth, any suggestions?



Hi Bob, Your Potterton combi boiler is losing pressure due to different reasons. Loss of pressure might be caused because of the leakage in a pressure relief valve, a problem in an expansion vessel, leakage in the heating pipework and air in the boiler. Leaking boilers, leaking radiators and leaking pipework can lead to constant loss of pressure in your boiler. Most of the Potterton combi boilers have built-in pressure meters you can use to check easily if there is the loss of pressure, as boiler needs continuous water pressure in order to run properly.
