Hey,

We're about to move into a new house, and I'm trying to do some projects at the new place before we actually move. The seller made some comments about loving the high water pressure, which of course meant it probably needed checking.

Incoming water from the street is 100 psi. Pressure at hose bib is 90-95 psi. The house has a Wilkins PRV model 70 with a manufacturing date of 0405 (I assume that's April, 2005). The adjuster screw was most of the way in, so I tried backing it out multiple turns.

Now, at the hose bib, pressure seems to be at about 55-60 psi as soon as I close other outlets. Within 20 seconds, it goes steadily up to 80 psi. Another 30-60 seconds gets it to 90-95 psi.

So just looking for confirmation that this probably needs replacement.

Thanks!
Tyler

Thanks for the confirmation. Is the Wilkins 70XL a good choice for the replacement?

Also, the current one is single union. Is it worth using double union? I might take the opportunity to modify some of the other plumbing in that area anyway.

double union is easier if you need to change it later If its copper and the fittings arent one after the other no big deal unless you install a defective one I just had a defective one I installed coulda tried a rebuild but since watts was giving me a new one free and I had double unions a swap was easy it was an 1 1/2" double union sweat .
I dont have a solid opinion on brand or model watts and wilkins / zurn
