    I live in a townhouse and the pipes have started to "hum"... they never did before. Incidentally, the noise began after a plumber came to fix a toilet that was running. Any idea waht could be causing it??

    When he shut off the water supply to the toilet to do the repair, the washer in that valve may have become loose or dislodged ( happens a lot due to the age and non-use of the valve), and this can cause noises when water flows through it.

    If you know that the toilet fill valve is totaly shutting off, you can tell, when it's humming and you lift the float in the tank and the humm goes away.
    I think you could check the toilet shut off. Turn the house water off, relieve the pressure by opening a faucet. Put a pan under the valve in question and turn the hex bonnet counter clockwise and turn the handle and stem to the left, till the whole asse. comes out. There should be a washer on the end of the stem. Also look real good inside that opening to see if there is anything loose inside, like pieces of the washer .
