How much should i expect to pay a plumber to replace a pressure reduction valve?  I had a plumber come out  to do some other work and while he was there he checked the pressure and it is right at 90 psi.  He said it should be between 50 and 75psi.  The price he quoted me was almost $500.00  to change out a $67.00 valve.   Plumbing is one thing i wont fuck with, so no , i wont do it myself.

They make rebuild kits that only take a few minutes to replace.  Take a picture of it and carry it over to your plumbing parts house.  


Don't pay a plumber.

The biggest problem is usually the lousy installations on many.
You need  two valves to isolate the things and a a union joint in the isolated pipe section with the PRV.
Or you can dump all the water in the house piping into the room the PRV is in.

I replaced mine last year and spent about $90 for the valve, extra piping, and those nifty little connectors.  If I had actually known what I was doing, I probably could've done it for a lot less, but that said, $90 isn't bad at all.  I first worked my butt off trying to get everything cut out and installed, then realized I put it in upside down, lol.  But about 6hrs and a few trips to Home Depot later, I got it done.  

It's probably so expensive because the plumber is going to cut the piping and he may solder it back, which would probably be somewhere around 2-3hrs for a professional, including going to get the parts.  You can probably hire a cheapo Joe-Bob plumber to do it for less and they could still do a decent job.  

Looking back on it, it's really an easy job.  You might want to reconsider doing it yourself.  With a little more pre-planning than what I did, you can replace it and learn a little more about plumbing all at the same time.  

Take a pic of it and where it is in relation to your house, whether inside a wall (like mine) or outside.  If it's outside, $500 seems like taking advantage.

Its located under my water heater in my garage, he said it would have to be cut out because of how close it is to the underside of the platform the water heater sits on.He said it would take him about an hour to do the work. I completly understand the guy has to make money but he is charging $400.00 per hour for labor!  WTF?

If it's too high ask another plumber to quote you.



I installed a PRV on my main water line a couple years ago as the pressure we were getting at our place routinely was around 85psi.  I installed 2 soldered unions on either side of the valve, so essentially one side of the union is soldered, the other side is threaded.  So now if I have to replace the valve, I unscrew each union and slide it right out, then slide the new one in.  You should check about getting a similar setup for yours because you'll have to deal with it again after a certain number of years.

And that's a quick list of costs!

Although $500 seems high to me too, but I have not seen it.

Here's a quick video.  I would relocate a new one out from underneath the water heater.
