Thanks for the advice guys. Glenn

Great idea with the clamps! What kind of adhesive would still to sealed tiles though? Glenn

Hi folks. Can anyone suggest a suitable adhesive for sticking kitchen worktop upstands over the top of tumbled marble wall tiles with a sealer on them? The walls also aren't particularly even and the upstands are slightly bowed, so how would you suggest ensuring they remains in contact with...

Thanks Tony. Does this site have gas engineers associated to it that I can get in contact with to do the valve replacement, or is it advice only? Glenn

Hi folks. Thanks all for your help so far. From measuring the resistances it looks like the larger 2800 ohm coil has gone. I measured the voltages as DC across the connector with it unplugged, and the numbers still don't add up, but I guess that may be a consequence of it not being plugged...

Hi Tony. The multimeter was set to measure AC, as I assumed this was what the gas valve would receive as I couldn't see any transformers in the boiler (probably a poor assumption). The fact that I see 240v between red and green/yellow with the meter on AC made me think it was AC driving the...

Hi folks. My Potterton Suprima 50L will not fire and then locks out. When I reset, the fan comes on and I can see the ignitor sparking, but boiler does not fire. When I check voltage across the wires at the gas valve, between the red and green/yellow wires I see 0v until the ignitor is...

My central heating pump has begun staying on night and day. Doesn't matter whether the boiler's firing, the main (elecronic) timer's on or off, the room thermostat is turned right down, or the main controller is set to heating and/or hot water - the pump just runs continuously. Anyone have...
