Ok,right bear with me, it is a bath filler that looks like the overflow of a bath that you turn to get the plug to go up and down. It has a single inlet and a slot at front where the water comes out.
I believe as I also fitting a shower from a Stuart Turner twin impeller pump I would have to use a concealed valve for the shower with a diverter so you could turn it to either shower or bath filler, I have only ever fitted a bar shower from the pump before and don't want to make any costly mistakes.
I'm also able to bail on the whole idea and have a seperate bar shower and branch off hot and cold pipes from tanks for normal bath taps. and sell the freeflow thing to someone else!
I am fairly competent at plumbing, nothing has ever leaked yet anyway! and as I only have a very limited budget and managed to fit my last bathroom myself, I thought with a little help I would give it a go, and in case you were wondering, whoever is reading this, I am a woman which is why I'm rambling on !
Thanks Ali
