My combi boiler is four years old. 'Problem is that the pressure reduces erratically causing the boiler to trip. This can happen 4/5 times a day or, at other times, the boiler runs happily for several days. My heating engineer thinks this pressure loss is due to a leak in the pipes or radiators involving taking up the floorboards. My thinking is that it is a boiler fault as surely a leak in the piping would result in pressure drop at a roughly uniform rate unless there are particles in the piping which could provide a temporary seal.
Is there any part of this boiler that could affect it in this way and would it be an idea to pressurise the system and then isolate the boiler to see if the pressure falls. Any advice will be welcomed and appreciated.
