    Leak from knob under sink
    It appears that the shut off knob [the thing shaped like () under the sink], for the hot water is leaking. Drops are forming on the screw. I tried tightening it, but that did not help. :confused:

    Many thanks.

    Hi,
    I am not a plumber, just a sometimes do it yourselfer around our home.
    I would replace the valve that's leaking. The seals inside might be worn out, and no amount of tightening will stop it normally.
    If the knob and it's assembly "screws into" the part attached to the pipes, it might be possible to unscrew it, (after turning off the water, of course!), and buy just that part. I did that with a "metal" valve feeding water to one of our toilets.
    But, if the whole valve assembly is plastic, it would be easier to replace it all.

    Hi June,
    That () is called a angle stop. Exactly what nut is the water leaking out of?
    The big nut or the little one? I'll wait on your answer. Tom

    Yes, that puts the leak in the bonnet packing nut,(the one right behind the ().
    The solution is to snug up the packing nut until the leak stops. This shouldn't take too much since the leak's very minor. Good luck, Tom
