I got a basic water pressure test gauge from Lowes (orbit model #91130) and tested both the hot and cold lines for pressure.
With no faucets on or any other items drawing water, cold is at 98psi and hot (or not so hot since its not really running at the time of test), at little over 100psi. So not good.
Could it be my Pressure Regulator Valve is faulty and not stepping down the pressure from the street? I should also have mentioned that when we have two faucets on at the same time and we get a wining sound from the plumbing. It doesn't bang, just a whine, medium pitch.
I plan to get a second, better test gauge later this week since I don't think I should rely on one test and one gauge. Will get something more robust from a professional plumbers supply place - just can't get there today with work etc.
As for my location, and I only mention this because the Lowes guy asked, am located in Cobb County, suburb of Atlanta and Lowes guy said my pressure should be around 45-50 something.
