Hi, I have a Valiant 242EH combi boiler which is about 12 years old. Until recently it has been losing pressure, I have to top the tank up every other day. I have checked as far as reasonable practicable the pipes under the floor and have been unable to detect a leak.
I have checked the radiator valves and there is no sign of a leak there either, also there is no air getting into the system (none comming out of rad. when bleeding after topping up) I have tried Furnox pipe sealer but that has not worked either. Any help or advice will be much appreciated.
