    Hello,

    I have a minor leak in the cupboard where our hot water cylinder is located. We don't have a proper boiler, just an immersion heater.

    Before I start tampering with it, does anyone know what this part of the pipework is for?

    The leak is as pictured, above the transparent tray I have put there to collect the water.

    That's a Tee piece, which has been a pipe work branch at some time......the pipes there are of large diameter, indicating a boiler has been fitted at some time?

    That is a safety valve, very easy to replace.

    Thanks for the replies.

    Is this the same as a pressure relief valve?

    Are those 28mm pipes reducing to 22 at the tee? Can't tell with this horrible iPad thing I'm using just now.

    do you have a coal fire with a back boiler? or a gas back boiler.as that looks like a old style prv not used much now as the discharge the water all over the floor ( but you can still get them)

    That's a blanking cap, the diyer run out of straight couplings. You can tell by the ptfe tape on the threads.

    Why would there be a TRV located there......is it in case the expansion pipe became blocked or something?
    Just curious!

    who said anything about a TRV.

    And a PRV is on a pipe from a boiler or back boiler and it is used if the feed becomes blocked as the coal back boiler has no stat.
