My combi boiler is constantly losing pressure, within 12 hours of topping up. Theres also a constant leak from the pipe sticking out the side of the house when the system is running. Im lead to believe that this is a broken Expansion vessel. is this a costly job ?


boiler is 10 years old and have also been advised it could be more cost effective in the long run to change the whole boiler. Theres Baxi boilers with 10 year warranties which would mean i wouldn't need to get monthly cover for maintenance on it.

any advice gratefully received.
