I've been in my house, which was built in 1960, for about 1 year and a half. Over that time I've experienced some leaky faucets and toilets, but nothing major. I noticed another leak a few days ago under the kitchen sink, so I called the plumber (again). He fixed the problem and checked the water pressure in the house. It was determined to be 90 lbs. He said that it should be no more than 65 lbs. and that I would continue to have problems (even more serious ones in the future) unless I put in a pressure reducing valve. This is expensive and I want to make sure his opinion is correect. Does anyone agree/disagree that I need to put in a pressure reducing valve? Or am I safe with the pressure at 90 lbs.? If it matters, I did learn that the water company is sending 100 lbs. of pressure to my house. Thanks!
