when pressure Reducing Valve is working
1. Open and close any faucet to release any buid up water pressure in your plumbing.
2. Attach your water pressure gauge to a hose bib closest to your
PRV.
3. Follow the instructions as shown in this Watts video on how to adjust
a PRV:
The video
shows using a socket and ratchet to adjust the hex head adjusting screw but some
PRVs just have a slot for a flat blade screwdriver. Ignore the "upstream"
pressure gauge in the video. You won't have that. The downstream pressure gauge
is the one on your hose bib.
If the pressure reading changes as you
adjust the PRV, then it's working. In that case adjust it for 60 psi. If the
pressure reading doesn't change, the PRV is bad so replace it.
Note how much the guy in the video has to turn the adjusting screw to vary the output water pressure. That's all the turns you need to find out if your PRV is working or not. I don't know what will happen if you go to extremes in adjusting the screw so be careful in doing that.
After you get 60 psi on your pressure gauge by either adjusting or replacing your PRV, then the water pressure to your home will be correct. You can then continue to troubleshoot any problems if you still have any.
