I have a combi boiler . At the moment i seem to have to top up the system every morning and during the day as the pressure gauge has dropped to next to nothing. I have noticed that the over flow pipe outside is dripping water . Can any one out there help with this problem or what is causing this?
The pressure relief valve is either passing by or is faulty, thats why it will not keep pressure and leaks all the time. It is best to get an engineer to replace it as it involves draining the boiler and replacing a part, it is relatively simple but not a diy job unfortunately.
