    tapered edge plasterboard fixing and painting

    I'm replacing a ceiling using 12.5mm tapered edge plasterboard. Is it ok to put the screws into the tapered edge or should i fix it on the flat just before the taper starts? Also, once i have joint taped, filled and sanded is it ok to paint straight onto the boards?

    Glowworm 30ci pressure loss

    So to confirm that would be the following 3 isolating valves as detailed in the manual: "heating flow" the "cold water in" and the "heating return". By the way, having previously mentioned there was no water being dumped by the prv, it has now suddenly started dumping water every time we use...

    About 3 weeks ago our 30ci combi started losing pressure overnight (whilst not in use). The pressure would drop from the standard 1.0 down to 0.6 and shutdown the boiler with the red LED flashing. I had to top up the pressure every morning. However the pressure loss has now got progressively...
