    Hi
    Bathroom towel rad has started leaking a bit, about a drip every 10 mins.

    Was all fine, but I shut the water off today to adjust some hot & cold pipes to fit a new sink & toilet, when I turned water back on that's when the leak started.

    Pic attached, what's the simplest way of dealing with it? Am I right in thinking if I shut valves off I can unscrew this valves without having to drain entire central heating system?

    If it's leaking from under there does that mean rad needs replacing?

    Cheers

    Yes, you can redo the joint. This is completely different from the the hot an cold supplies though, they wouldn't affect it..

    Yes just turn both sides off (counting turns for balancing), open bleed vent to make sure they’ve turned off, drain radiator and inspect/repair the leaking rad tail. Reconnect, open valves close bleed vent once water runs feeely.

    Thanks.
    To drain I'm just undoing the offending valve and letting water run out?

    I won't need to add any inhibitor will I?

    Well this is fun. Planning on doing this tomorrow as it's getting late in the date.

    Heating has come on, now rad is weeping from the nut at the back and no longer from top?!

    I've tried to tighten this but can't really tighten it anymore.

    Shouldn’t need inhibitor for the amount drained out. Drain it how you want. Chances are the olive maybe crushed, if you can’t go anymore.
