High water pressure outside; low inside house
I have been searching for an answer to my unique problem and I hope someone can help. I have extremely high water pressure on the outside front hose bib (115 PSI). I've already had to replace part of the water pipe coming in from the street probably because of the high pressure. The plumber who did this could not figure out why the pressure is so high outside but so low everywhere inside. He said if I put a pressure regulator valve on that it would probably reduce the inside pressure even more. Anyone have any ideas? Thanks!

Is the pressure low or the flow low inside? Don't confuse the two.
Did he measure the pressure inside as well?
Low flow can be caused by pipes that are narrow.
I don't remember if he measured the pressure inside, so I guess the flow is low.
The plumber did not see a pressure regulator installed. I'm thinking of calling another plumber for a second opinion. Thanks.Originally Posted by jimbo

The PRV may not include the hosebib. That can happen. I would trace the lines back and see if I could spot an old PRV, which may need replacement.
