Hi everyone, got a problem. Been called in top have at look at Worcester 24cdi combi boiler. The pressure creeps up to 4bars. There must a fault with the safety valve, but does anyone what the cause is of the increased pressure.
It is one of those ones with the key that push up from underneath to fill it up so it can't be getting extra water.
Anyway over to you lot, answers on a postcard to ?
