Water Pressure Reducing Valves
I just purchased a house that has a water pressure reducing valve installed. Plumber who inspected system before sale says I need to replace the PRV with one that reduces the pressure even more because service pressure in the area was increased recently. I have read some older posts on this subject and now think this advice is suspect, since the valve either reduces the pressure or it doesn't. That is, unless the valve is broken, the PRV should be reducing the pressure to a proper amount (code) already. Plumber showed me pressure at hose bibb 90-100 psi. House is 1 story.
