    Hi all
    I've gas in the house but the problem I'm having is the vent in the hot press is leaking,
    I've depressurised the system to stop it and I've a replacement got so is it just s matter of switching the vents and repressuriseing the system?
    Thanks

    It should be , but are you replacing the air vent with the exact same type ? if they are the type with the black cap i think they are ****e and always leak for no reason after years.

    I and many other plumbers use the red cap , Flamco brand ones, i must have installed hundreds of these and have not once seen one leak.

    hi put a value on so you can replace next time without draining down system ie penny value before air vent

    that's a great name 310. would you remember the solder fittings called 101 and 105 and 108. I think there called t10 t15 t18. sorry for the post. your user name has brought memories back. jesus I spent me first year learning all them numbers. now there all changed.

    I spent one year only with lynskeys and that 1st year of plumbing I spent with lynskeys. 310 315 318 101 I was like a fcukin calculator in that stores

    Maks sure the little black cap is open , also make sure that the balancing valve on coil ( if fitted) is open a turn from closed , if all this is correct , and all zone valves are open and cylinder ztat is set to 60 , try turning boiler on and shut all rads to get circulation through coil , leave for half an hour then open rads back up ,

    Should the black cap be loose? It tightened down tight

    Yes it should be loose , id doubt that is your poblem though , id say you may need to shut all rads for a while to get circulation through the coil , , make sure the balancing valve is open a turn on the return at cylinder coil .
