As you'll see from the attached images my en-suite shower has separate temperature (top) and flow (bottom) control valves.
Guessing the flow control valve is on the way out as the shower has moved on from a drip to a proper run from the head.
Have removed the grommet screw from under the flow control valve cover but cannot get the silver cover off for love nor money. Have tried twisting both ways and prising but nothing.
Any ideas?
Thanks
Paul
