Thanks for the very speedy reply. The new expansion vessel doesn't seem to have a method for re-pressurising unlike the original (it had a valve similar to a car tyre). The pressure drop seems a little high (I'm not a Gas Engineer) and remains constant (about 0.5 bar) until the hot water tap is...

Thanks in advance for any responses. Basically my central heating system is losing pressure but I cannot find any leaks. It's losing around 0.5 bar in a day. I've checked the overflow pipe and the water is not coming out of there. It's possible that the leak is under the floorboards...

Thanks Paul I've tried re-pressuring it following the instructions in the service manual but it doesn’t seem to keep its pressure. prv ? Is this pressure release valve? How do I actual get the old one out? Does it just screw out?

Could any explain how to change the valve that is attached to the expansion vessel? I’ve had a problem a couple of years ago with the expansion vessel and it turned out to be a fault valve. An engineer replaced the valve and the problem was fixed. The problem seems to have returned. It may be...

Cheers for the speedy responses. Yes the switch is inside the house (so is the Gas pipe). The pipe is running up the wall inside the porch and the best place for the switch is next to the pipe. The only reason I ask was that a Gas engineer once questioned if a wall socket was too...

Sorry it took a long time to respond to all the advice I received. Just to let anybody that's interested the problem turned out to be the pressure valve at the top of the expansion vessel. After several plumbers told me the expansion vessel need to be replaced (none of them wanted to do the...

Thanks for any replies in advance. I would like to fit an external light (PIR operated) just outside my front door. The problem is I would like to put the switch to control this light right next to the Gas pipe that feeds the house (about a meter above the Gas Meter itself). Is there a...

I have a problem with the pressure in my central heating system. The user instructions state that the system should be pressurised to between 1 and 1.5 bar when the system is cold. I have recently drained a radiator and needed to restore the pressure back to between 1 and 1.5 bar. The...
