After fitting a new toilet and handbasin downstairs I decided to replace our old sage green bathroom suite and am using plastic speedfit pipes and fittings.
The original pipe work was copper, the sink and toilet have gone in fine using the plastic pipes etc,.
My problem is with the hotwater pipe for the bath. I have fitted a valve onto the original copper hot water pipe which has a screw that can allow the water to be turned off or on. Into the other end of this valve I have used 20mm plastic piping. I can't stop it from leaking. I have tightened up the pipe into the end of the valve with an adjustabe spanner and pipe wrench and thought that I had solved the leaking. I turned the water back on and it seemed fine but then the pipe shot out of the end of the valve and there was water every where.
Where am I going wrong? The water pressure is high but the cold water feed to the bath is fine.
Any tips please?
