Thanks guys. I will go and check the air pressure in the expansion vessel. I think I can use a standard car pressure gauge for that. If it is flat (and not leaking water), I guess I can pump it up. Will I need to reduce the water pressure first? If so, can I do this from the bleed valve on a...

I don't have any pics at the moment but will have a look to see if there is much to see. I have had to re-fill the water quite frequently. When the boiler is on, the pressure builds-up quickly and reaches >3bar causing the PRV to trigger releasing water from the drain pipe. Once it cools...

Okay, I think I'll try seeing if water escapes from the valve. Going back to my original question, how much hassle is it to replace the original expansion vessel, i.e. how many hours of effort is that likely to be assuming that the boiler needs removing? I'm wondering about this because I'm...

Thanks for the replies so far. He said that the seal was knackered although he didn't do anything to prove that. I thought he might try to pump it up, but he didn't. For the exterior tank, how much space would it take up? The boiler itself is situated in a cupboard.

I've been having problems with my Maxi Combi boiler. I called a plumber and he said that the expansion vessel needed replacing and that although the vessl itself only costs around £70+VAT, it would take a day to fit and hence another £500+VAT. He suggested I might be better off with a new...
