I too have one at the utility sink that is after the PRV, which is
good since the rear hose bib is soon to be at street pressure.

I'm gonna try one of those SnakeBite Tee's to tap into the pipe at the
front of the house and run PEX to the rear hose bib.

Or replace a defective one (BTDT)

Hopefully, it's preset. Mine was.

True (or less, I paid $12)

> Screw it on to any hose bib to use it.

To *use* it, that's true, but *which* bib you use might depend on what
you want to check.

The hose bib at the front of my house is before the PRV and therefore
at street pressure.

The hose bib at the rear of my house is after the PRV and thererfore
at "house" pressure.

I knew my PRV was bad when they both read about 85 psi.

And yes, the chattering went away after I replaced the PRV.

reply: I have one of the gauges. Will check the pressure next trip to
Vegas.

Steve

An expansion tank (about $40) might work. It protects your water
tank, creates a buffer in the piping, saves appliance valves too.

That would be the wrong tool for this particular job.
