Leak from Isolator valve tap connector nut on bottom fill cistern

Well done mate

Had to replace a plastic fill valve with a brass shank one after the plastic shredded the fibre washer.

Brass tap connector to brass shank with a bit of paste on washer and doesn't go inside valve.

Plastic shank only to flexi with rubber washer or plastic nut and its rubber washer and no paste of course, not necessary and rots rubber.

Used to put brass to plastic without second thought before, but since one leaked, plastic to plastic and brass to brass only from then on.

I agree with you totally. I won't fit plastic float valves.

Must of been fitted by a gorilla.

That gorilla would have been me.
It wasn't anywhere near tight... So I kept tightening it.
The plastic edge was thin and razor sharp and butchered the washer.
