    Hi, I want to change my bathroom sink and when I have looked at the stop valve at the bottom of the hot water cylinder, there is no wheel to close the valve. When you look at the valve you can see a square nut inside, but you need a socket that fits inside to turn the nut. What kind of socket do I need to close the valve, it's a mystery.
    If I can't close the vave, could I empty the cylinder to do the job?
    I moved into my bungalow 2yrs and I have only just found this issue.
    I hope someone knows the problem.
    Thanks Dave

    take a picture, it could be the drain point you're looking at if it's at the bottom.
    your isolation valve cold well be up in the loft on one of the outlets.

    Maybe a multi 4 way key is what you need - but if you can stop the water flowing into the large header tank in the loft (by holding the ball valve up with some string) you can run off as much water as you need.

    That is a balancing valve for the boiler. Not an isolation valve.

    Hi, thank you for your replies. I have just found that it is a Lockshield gate valve. Can you please tell me what I need to do to close the valve?
    Thanks Dave

    Take the shroud off and use a shifter.
    As Dan said, ...You probably have the wrong valve.
