How to connect brass compression fitting to plastic thread

paul123

Hi
Can anyone please advise a foolproof way of making a once only watertight fitting connecting a 15mm brass compression fitting on to a plastic threaded connection on the waterfill on a toilet. Because of the lack of space around the toilet I can only make this connection once with no tightening the joint afterwards as I have to then work backwards to refit the toilet from this connection.
Thanks

My advice would be to go to you nearest plumbers merchant and purchase a Hep2O 1/2" tap connector which will make a relaible joint onto your plastic ball valve and then run off the tap connector using Hep2O plastic pipe.

It is far more reliable than using a flexi hose. You do not say if your water supply is mains or tank fed.

Good luck.

Ah, you forgot to mention to the OP he will also require inserts and the appropriate pipe cutter, to do it your way


flexi's are used throughout EUROPE, their fine as long as you don't kink em, or tie em in a knot.

That may be, but I have been called out to too many floods caused by knotted/badly installed flexi's to have any faith in them.

In my experience, too many people use them to correct the misalignment problems they can not be bothered to sort out correctly.
