I have two outside water spickets. One before my (in home) pressure regulator and one after. Both read at 140psi+- a very little difference when I adjust regulator. BUT when I lower the pressure on the regulator it really kills my pressure in my house! You can't hardly take a shower or wash dishes and the pressure is just below 140psi

140 PSI is very high average hous pressuer should be 45-60 PSI in this case you may have a bad PRV or a badtest gauge, Thanks.

Thanks john for prompted response. I understand that its really high. It was check with a plumbers gauge and my friends gauge. Both said the same. My question is if my PRV is bad, how does it make my shower and whole up stairs have extremely low pressure when I adjust it?

How old is your home? What material are the water pipes? Plastic, copper, or galvanized iron? Back to you, Tom

Built in 1999. PVC pipes. I had to turn the pressure back up a little yesterday because my upstairs shower didn't have much more than a sprinkle of water coming down. That's what I don't understand how I barely got pressure upstairs. I just put a brand new tank water heater in due to the pressure ruining the other one. This new one has already flooded my basement twice due to the pop-up valve releasing water so much. And no I don't have my pop up valve plumbed to outside yet. It goes into 5gl bucket. Ive also had to replace all shower valves and water inlines to toilets. Craziest thing. It may be the pressure regulator. If you can't think of anything else it could be then I'm replacing it this weekend.

Does that mean hot, cold or both.

One hundred forty is a very high PSI. Pressure regulating valves have an operating range. Suggest that possibly the 140 PSI is above the operating range of your PRV. Check PRV, should be labeled as to operating range.

I check water heater today(in basement) at the drain in the bottom and it was 135-140psi. Funny thing is that I still don't have pressure upstairs in the house!!
