I have an Aqualisa Thermostatic shower running off a Combi boiler. It is about 13 years old and the thermostatic cartridge was replaced about
6 years ago. I note from Andy's post a little lower in the board that it is probably time for another replacement !However, it was functioning fine until a week or two ago when I noticed it was dripping from the barrel. I assumed that the gasket had gone, ordered a replacement from (the excellent) Aqualis spares Dep. I took the cartridge out, cleaned it all up and refitted with the new gasket, and guess what - yep still leaking. Repeated the operation - with no improvement. It seems to be coming from around one of the 4 screws holding the cartridge in place & It is getting worse.
So my dilemma is... if I replace the cartridge at £100 will it cure the leak ? i.e. are the units prone to cracking and leaking (I cant see anything). Or is it possible that something else is causing the leak ( e.g.warped unit) ?
Thanks for any help. comments thoughts and advice.
