Discuss Left most pipe tap leaking under boiler - please help! in the Plumbing Forum area at

    I have a dripping leak coming from one of the black taps under my boiler. It means I need to top up the pressure every 2-3 days.

    The pipe the tap on is a hot pipe when the boiler is on. It is the most left pipe on the image!

    Could anybody please help/tell me what's wrong and how to fix?

    Is it leaking from a nut or the actual valve part ?

    as above does leak from the chrome nut or from the middle of the black handled tap? If so you may need to get an engineer out to change that over.

    It's coming from the black tap itself, looks like it's from the screw in the centre of he black tap, but can't tell for sure and it doesn't tighten... is it expensive to get that changed?
