I am getting a humming noise in my kitchen (not very loud or scary) which
lasts for about 10 - 15 seconds, shortly after turning on the kitchen hot
tap. I've also noticed it in the bathroom, when running the hot tap there. I
think the noise is coming from the water pipes, but I'm not sure where or
Does anyone have an idea of what it might be ??
I have had this problem too....it only occurs when water has been used and
the system is filling back up again... the critical factors are water
pressure, flow rate and pipe length. It occurs because water is
incompressible and what starts is a pressure wave bouncing down the pipe
which bounces back at the control valve and bounces back again but this time
reinforced so that eventually the pressure wave builds up to cause physical
movement of the pipe which causes the low frequency humming noise. If it
wasn't for the fact that the system flow rate is changing the humming would
continue, but it is because it changes that causes it to subside.
Its akin to you sitting in the tub and moving your body forward to create a
wave and if you time the movement of ur body a second time in
synchronousisation with the reflected wave the second wave will be
reinforced ad infinitum until it spills over the edge of the tub, however if
you time your body movement after the first wave rebounds from the end of
the tub such that your body motion combats the reflected wave then the wave
subsides rather than gets reinforced.
If it bothers you the solution would be to fit a pressure reducing valve on
your water supply coming into the house.
consult unfortunately and it is a problem looking at some of your comments
because the products and even your descriptions are different from ours.
In the UK fawcet is tap, bath is tub..and there are a lot more that leave
Notwithstanding that...I do appreciate some of the advice given here,
although I must admit to only looking at the newsgroup when I have a
