I have a leak from the expansion tank on my Baxi 105e and have been quoted silly money to fix it. I am very handy and will have a go at almost anything including this one. Tips and shortcuts would be appreciated especially when I need to refill the boiler.
it would be much easier and cheaper to fit a remote vessel next to the boiler these are quite bulky but save a lot of time because you do not have to remove the boiler of the wall

will be easier to cap the old one off and put an external one if you have the space ?
