    I need to do some maintenance on the bath shower mixer tap but I cannot get the hot water to shut off completely.

    I have fully turned the gate valve off supplying the cylinder from the tank in the loft buy its still flowing slightly from the bathroom taps and doesn't appear to be stopping.

    Can anyone tell me what I can do?

    Bung the outlets from the loft tank .
    Gate valves are notorious for not closing fully ,and not opening after closing.
    You could also turn off the mains supply to loft tank ,and run taps to drain it ,but that would waste all your stored hot water.

    Turn off main stop valve to house feed and turn on all your hot water taps untill flow stops, if you are lucky you may have a seperate stop valve that just feeds the header tank that you can use instead of turning off main valve

    You could try, if you have not already, closing the gate valve then opening it a few times, with a little water flow through it. It might help. If the valve is difficult to turn, loosen the gland nut a little, it may weep a few drops of water though. Do it up again after until the weeping stops, not so tight you can't still operate the valve.

    Any decent plumbers merchant. Or make your own from a cork ,or rubber stopper. If all else fails ,a carrot will do it !!

    A wine bottle, do the job and then treat yourself. :)

    For 22mm a standard cork might be too small ... a champagne one would be better.

    If the bathroom is upstairs try opening the hot tap downstairs.
    This may be enough to remove any flow from the bathroom.

    I’ve ‘bunged’ the tank a couple of times using a rag, twist a corner into a spiral, feed into outlet then ram in with a long screwdriver to compress the cloth (use a decent enough rag / old tea towel that won’t disintegrate when you pull to remove it)!

    Have read similar posts on here when a carrot have been suggested but I don’t actually know if the guys or being serious or not ?

    My worry would be the carrot getting stuck in the outlet and snapping off and/or getting jammed in the pipe

    Was going to buy a set of rubber bungs but can’t justify the cost when I may need one on the very odd occasion

    Couple different types out there;

    Rubber cone that’s fits a multitude of outlet / pipe sizes. Just ram it in the hole and twist to get a good fit

    Also compression type bungs that fit specific pipe sizes. Insert into bung, tighten to compress rubber and form a seal

    However, for a one off job, use a rag, or a carrot, parsnip, mouli, cork, etc

    The carrot /parsnip is a serious comment ... best putting it in a plastic bag, just in case.

    Excellent suggestions from all of you thanks. I too couldn't warrant buying some rubber bungs for the price they are, I might use the rag method or make something, not so sure about shoving vegetables in the hole, I'll save that one for the missus:D

    Just to update everyone I managed to stop the flow from the tank in the loft by using as someone suggested a cork, job done and thanks everyone for your comments and help.

    What's the difference between carrot, parsnip, cork? They are all vegetable matter!
