Problem with Leaking Toilet Inlet

angelavdavis

Hi all,

DH and I have installed a replacement toilet in the ground floor cloakroom.

We have got a persistent leak around the plastic valve which is connected to the water inlet. We installed the black rubber washers, have used a spanner to tighten it, but still water is dripping from around the sides of the washers. We loosened everything, put some LSX around the thread, replaced the washer, tightened the plastic nut but still it is leaking.

We had previously water tested it before installing by putting a large jug of water in the cistern and there wasn't a leak then, it seems it is when it is under pressure.

We are at a loss what else to do!

Any ideas?? Thanks

Pipe might not be fitting straight onto the ballcock connection, make sure it isn't under any duress. The ballcock threads may not have been made properly, take it apart and make sure that there is a beveled edge on the end of the ballcock. The rubber O ring inside the plastic valve may have a tiny nick in it, again check it to make sure it is sound, if it isn't replace it. If the problem still persists replace the plastic valve with a ballofix vale and a small piece of piping connecting to the ballcock.

Also - don't over-tighten any fittings.

LSX on the threads will achieve nothing. Put it on the washer and you might get somewhere. Ditto over tightening.
