Having purchased a mains water pressure guage, my reading when just this tap is running is 2.5bar. When one tap is open this drops to 1.5bar. I'm on shared water mains at the bo...

Hi,

I can confirm that when the heating is switched on, the hot water must also be selected. I think it is a 3 port valve. It is an open vented system, and I beleive it is a gravity fed system

How do I remove the airlock?

Many thanks for your help!

HI Nitro My cylinder (storage water tank) thermostat is an odd one - the dial has numbers 1-9. Currently this is set 5. I'm having to switch this on to heat the water as the boiler is not storing hot water in this tank/supplying it to the taps. The boiler thermostat is set at 2 (1 being for summer a...
