Thanks for your help. I do not have the FPS or the pipe size (1 inch I think though). However, I believe you are correct in your diagnosis. I went downstairs and turned the main valve to our house down (almost to closed) and the squeals have subsided. I also had to turn the flow into one toilet down. The water pressure to the faucets and tubs seem to be about the same so it evidently did not slow the water down too much by turning the flow into the house down.
I have to ask you . . . is there a way to correct the problem without turning down the flow to the house from the main line? A new valve or something that lowers flow?
I really appreciate your help.
Thanks
