I am fitting a new bathroom suite in my bathroom but have come across a problem. the pipes in the bathroom are 3/4 inch and the couplings and pipe i have are 22mm i have checked with all the shops in my area but cannot find one that sells 22x3/4 compression fittings or anything like it. surley you can get these. can anybody point me in the right direction and tell me a shop or company where i can purchase such things. Thanks in advance. P.s WHY DO WE CHANGE THINGS THAT WERE WORKING FINE.
