I just replaced a standard low-flow shower head with a 5-setting massaging shower head. Now, when I turn on the shower I get a high-pitched squeal from the shower head. The squeal goes away if I set the head to full massage, but any of the other settings I get the squeal, at various pitches depending on which setting I use.

What can I do to make the squeal go away?

TIA. sdpuzzles.
