I recently stumbled across this group and it seems to be full of useful information. I'm hoping that somebody can help with this question..
I'm fitting an in-wall cistern for a new WC. The instructions that came with it are sparse to say the least. To connect to the cold water inlet, an isolating valve is supplied, but I don't recognise the fitting on the end. It seems to be a half inch thread with a fairly hard rubber type ring about half way along which a 1/2" female connector cuts a thread into. (If this description is not good enough and anyone is sufficently interested then I could email a photo)
Do I just use a standard 1/2" female iron coupler (screwfix no 12341) to connect this to the 15mm pipe?
Any help would be appreciated. John
