Got a new gas condensor boiler a couple of months ago as we got an extension. Builder's plumber installed it. It has broken down once, and the plumber said it needs to be topped up every few months. He didn't explain this at the begining. Is this normal? I know the water pressure is not great in the area where I live, I don't know if this has anything to do with the boiler needing to be topped up.
Any advice and comments greatly appreciated.
