Stop the high-pitched squeal from water pipes by replacing the shower head or adding a flow control valve. Or simply replace faucet parts with a rebuild kit.

An add-on flow control valve often stops the high-pitched squeal in a shower.
Puzzled by a high-pitched squeal when you turn on your shower or other faucet? This is what's going on. Water flow at certain pressures can
create harmonic vibrations in pipes,
making the high-pitched sound you
hear. If the problem only occurs when
you turn on the shower, begin there. Worn
water passages or parts in the shower head
or valve (washers, O-rings, etc.) sometimes
allow air to mix into the water stream or
create a pressure imbalance. First try the
easiest fixes. Replace the shower head or add
a flow control device (about $10 at plumbing specialty
stores) on the shower arm to see if
that stops the sound. If not, replace the wear
parts in the shower valve or diverter. Most
valves have replacement kits that supply all
the needed parts.
If these solutions don't work, call your
local water utility and ask about the
water pressure in your area. High water
pressure sometimes causes the pipe
noise. If your water pressure is high,
you can hire a plumber to install a
whole-house pressure-reducing valve.
Have the necessary tools for this DIY project lined up before you start—you’ll save time and frustration.
