We are having problems with the plumbing in our main shower/tub. Rarely can we shut the water flow to the tub all the way off, and now we can regularly hear a high pitched noise from the tub while the faucet is OFF. If I build the water pressure up enough it will stop, but as soon as I turn down the water it starts again. What is the best way to pinpoint and then fix the problem?

We meed the brand name of the valve and a discription or a model number. Regards, Tom
