So, the cistern pictured is being a bit of a pain. It seems to be constantly filling but really really slowly... as if the water is at high pressure but isn’t able to get through where it should very well... other than a spray at the top of the fill system on the right of the cistern... due to the tight fitting of the cistern it would look like a bit of a pain to get in and swap bits round... from the picture can anyone tell me if the parts in this cistern are replacable or am I best replacing the whole thing.. if that’s the case... where would you advise getting one from? Thanks as always..!!
