Dan1983 Posted February 21, 2023 Share Posted February 21, 2023 Evening all, Looking for some pointers on how to seal our cistern flush pipe. we have limestone floor that is un-even and it seams after a month or so the toilet must move slightly and cause the cistern flush pipe to misalign as it enters the pan then leak. The toilet has a built in sink unit so you cannot really access anything once the toilet is in place. So far I’ve tried all the different flexible pipes and none are short enough as the cistern is quite low. Also found they restrict flow so front of the pan is not washed on flushing. Has anyone found a flexible cistern pipe seal? Running out of ideas! Cheers for any pointers! Link to comment Share on other sites More sharing options...

Dan1983 Posted February 22, 2023 Author Share Posted February 22, 2023 I’m afraid I don’t have a picture of the plumbing set up at the moment. Will look to pull it out for the 3rd time next week! It was a fairly cheap set up as could not find anything else at the time that was short projection. Would be easy if the tiler had not tiled the complete lower section as I would have had access from behind the unit. Below is the set up and joints I have been trying to use Link to comment Share on other sites More sharing options...
dpmiller Posted February 22, 2023 Share Posted February 22, 2023 isn't a flush pipe normally 38mm? sounds like your flexy pipe will be loose in the back of the pan surely Link to comment Share on other sites More sharing options...
