Easy job made hard. Tail spilt. So off the Screwfix - all theirs had a compression fitting and I wanted one with a 1'2 inch BSP to screw onto a Isolating Valve. Tried Plumb Centre - same sort of stock
Amazon - success.
I really didn't want to faff about changing stuff behind the pedestal.
Why don't they make things more readily available to screw onto an isolating valve?
