Yes to both
There's a small silver screw in the centre of the "head" of the lever... that one?
Hi, did that, then tried to move the inside part sideways with small pliers.... that didn't work either. Nothing looks old, rusty or corroded so I simply don't understand why they're sticking.
No, not even a nano tiny bit. I will call the guy who serviced the boiler tomorrow and will ask him to spare me the call out fee.. he works for the company that fitted it and showed me how to top up the pressure when needed, including giving me a diagram.This guys was new though, he'd never done the annual service for me before. Is there any way these things can be fixed to a stuck position?
OK. Thanks all the same... just out of interest - is replacing the filling loop likely to cost me a bomb?
Thanks, ***** ***** appreciated.
