The radiator vale in the bathroom is leaking where the tap part screws in and out, i can loosen the collar but how do i remove the collar so i can get to the working parts. Thought i would just remove the end cap on the tap part to find a screw which would then loosen to remove the tap and slide off the collar but it all looks like one piece. Hope this makes sense.
