Default Leaking PRV

I need some help please. My PRV is leaking about one drop of water every 30 seconds. Yeah, I know it needs to be replaced, but so does the gate valve below it, and the entire configuration. Since I'm going down for surgery again next week, is there a stop gap measure I can do to stop the drip? Can the adjustment bolt be tightened to stop the drip, since it appears to be originating there?

Can you back off the stem....wrap it in teflon tape and re set it?

I suppose I could try. I normally just replace them, but in a crunch for time.

Use the thicker thread sealing tape as opposed to the thin white stuff. Mine is pink.

For a temporary repair a O ring backed up with a washer would work better then T-tape.

The PRV was shot, so I replaced it. I had also purchased the parts to replace the main gate valve with a ball valve but the street shut off ball valve was frozen. Had I torqued on it anymore, I would have busted it. I called the city and asked them to fix it, since it is on their side of the meter.

A question for the experts. I never checked the pressure with the old PRV, but after installing the new one, the pressure was noticeably lower. Since I couldn't find the pressure gauge, I screwed in the PRV adjustment screw a few turns, until the pressure seemed similar to the old PRV. I then found the pressure gauge (figures, right?) and see the pressure is set to about 71 PSI. Isn't this at about the high end of normal? Should I back it down a bit?

71 PSI is toward the high end of acceptable. Code here requires a PRV anytime the pressure exceeds 80. You will experience faster wear on faucets, fixtures, and piping.

Me? I like a 65-70 PSI shower, and am capable of fixing whatever breaks.
