I live in a condo, in Lincoln, CA that is 13 years old. I had a plumber out because the tub spout was dripping. He was able to stop the dripping, by applying pressure but told me that I had high water pressure of 95 lbs and suggested installing a gadget on the water source, outside the building to reduce it. In all my life I have never been told that I had high water pressure. It is going to cost me $525. Is this a correct diagnosis?
