Hi,

Seems a simple problem but turning into a pain in the posterior! Replaced the inlet valve in my downstairs loo as it was leaking (related to the thread about stopping cold air from the overflow - same cistern!) but am now having a problem sealing the connection between the copper inlet pipe and bottom entry valve.

There was a normal tap connector there previously which was also corroded to heck and had to be replaced. But no matter what I do it won't seal .... Now the problem is exacerbated by the fact that this cistern is fed from the mains (1985 house with 3 loos so this was done for the plumbers convenience!) so the pressure is higher. A normal tap connector only pushes into the valve entry by a couple of mm which doesn't seal too well so I'm looking for alternatives.

I reckon I may need to improvise but was wondering first if there was a better solution than a tap connector? I was thinking of just using a direct connection to the 15mm pipe, which can be inserted a couple of cm into the entry pipe, with some sealant around it and a brass or plastic nut to compress the plastic.

Ideas?

Are you meaning the underneath filling point of your systern? I use flexible braided tap conectors... You will or should have a ball valve on you mains pipe, the tap conector will fit onto the systern no problem and you might need to cut the pipe coming out of the ball valve, i use either ptfe tape or some jet blue sealant paste to all the joints. hope this helps

Yeah that's the one. The inlet to the cistern - bottom fill. Trouble was it comes off the mains so is higher pressure than it should be - that'll get sorted at some stage ... Anyhow, a normal tap connector wouldn't seal but when I was going thorugh my box of plumbing bits (never throw out things that could be useful!!!) I came across one with a longer 'insert' for the pipe. With plenty of ptfe tape and some silicone sealant around the gasket it tightened up with no leaks.
