    Hi,

    A valve on the CH return started leaking while I was repressurising the boiler. This may have been why it needed repressurising but I hadn't realised.
    Is it possible to easily replace the valve or should I get a plumber to do it?
    It leaks whatever position its in so I've drained the system.
    Any help much appreciated.

    Turn the black cap clockwise and see if that stops it.

    As @The Novice says, that is simply a drain cock and just tighten it clock wise using your fingers and it should stop

    Hi sorry I wasn't clear and the photos aren't that helpful.
    Its the thing to the right of the drain cock that is leaking. I figured out how to put an arrow on the photo now. It can be turned through 90 degrees, I thought it was an open/close valve.Thanks.

    First pic shows a drop of water from the drain cock ? Latest pic shows no water ,but if it is the isolation valve it needs replacing ,and it's generic to the boiler.( In other words a boiler part)

    As @terryplumb says the isolation valve is part of the boiler, and wait till you see the price of them

    In future, use the correct size screwdriver and not an axe.

    Or even forgo the screwdriver and use an adjustable spanner

    Thank you all for the help. It sounds like I need a new drain/isolation valve then.
    I'll be more careful in future, it wasn't an axe it was a pair of pliers. It was all I had to hand and there was quite a lot of water comming out. Not that turning it made a difference.
    Thanks again.
