[Shop-talk] pressure reducing valve

[scott.hall at comcast.net]

yup, that's what I'm talking about. in my estimation its purpose is to regulate the pressure coming out of the tank. I called it a pressure regulation valve because that's what it said on the box of the new one I bought and what the guy at the plumbing supply store called it. 

I suspect its only benefit is to protect the fixtures from a super-high-pressure well tank, which I don't have, and the drawback of not having one will be slightly noticeable water pressure differences. since the new one doesn't fit in the old one's gap in the pipe, I've decided it will be easier to just plumb it with more 3/4" pipe and take the prv back to the store. I'll report if anything blows up at the house from 70 p.s.i. tank pressure.

It sounds like the item Scott is describing is not really a valve, but a 
pressure regulator, in-line with the water supply. These are not 
uncommon in houses with municipal water when the street pressure is 
too high. Still don't understand why you'd want/need one with a well, though.
