Water Pressure Regulator Replacement and Adjustment 

This was awesome, just saved myself a $750 quote from a plumber. Took me literally 5minutes start to finish. Excellent tutorial!

This is a really good video! Excellent up close clear view of all subject matter and you covered all aspects of how to make the replacement ( backing up the valve while unscrewing the unions, facing the valve inlet with direction of flow, bleeding air out of lines and the main one.....turn the water off first). Great job. You have the approval of a 45 year licensed master plumber ( retired).

I’ve been looking for the answer to my issue all day long on RU-vid. Hurray! Thank you for the clear & concise video. Mine is outside in a garden bed under a green box in my 100 year old house. All the parts on the regulator have rusted and corroded completely. I love learning how to fix things in this beautiful historic San Diego house. It’s worth the headache. Lol

BEST video out of all that came up. Thx for posting, clear, concise directions. Great detail & video.

I'm almost done with a pex home run system in my house and I was stumped when I found this. I did not know what this was when I found the main coming into my house. I thought it could've been a valve and thought that was stupid of them to do that when they built the house. The same day, youtube recommended me videos on water pressure regulators. Thanks RU-vid. You learn something new everyday.

This is an excellent video. Along with plumbing, you have a skill for making great detailed content. Thanks so much!

If only all videos were this complete! Great job!

Thank you for this video. I got it installed start to finish in 30 mins. 💪🏾

Thank you! This was the best "how to" video I've watched of thousands over the years, great job and thanks again!

It's easy to miss when a regulator has gone bad. It's not something we often think about. I usually notice multiple toilets have a very low water flow contentiously, even when the tank has refilled. And almost always I'll first replace a filler valve because I only noticed it on one toilet. And it doesn't work, so I started leaking abundantly. You might also notice increased noise in plumbing in general, bursts of high water pressure when you first open a faucet. A $10 investment in a water pressure gauge is well worth it. High water pressure can ruin other plumbing or connected appliances, which can get quite costly. Replacing a water pressure regulator is generally fairly easy DIY project if you have the tools and clear access. This is a great video for showing the simple steps involved. And it's insane what plumbers will charge for such a simple procedure. They must love it when they have a naive homeowner with a leak from the high line pressure and can charge several hundred dollars for a 20 minute job with a

Thanks for this video! I was having a hard time getting the nuts off of the old regulator, so checked out your video. Holding the body of the regulator with a large wrench was the answer. Everything else was easy after that. Thanks again.

Thanks for sharing your knowledge.. Its good morals to share. Lot of people dont like to share what they know.

Thank you. Had to end up doing this myself after my plumber kept doing a no show to my home. Thank you so much!!

Thanks for your excellent guidance, and I replaced my valve successfully.

One of the follow the steps and don't rush what you are doing thank you for the how to

Thanks for the advice.I called Watts company and they suggested me an alternative which was a compatible match .I had installed and works well.thanks for the insight of your videos which helped me learning new things.tks

Thank you very, very much. I followed your directions, but I put Plummer tape as an extra precaution and habit. Your video gave me the confidence to do it, and I made it happen. No more banging pipes and my PSI is normal.

❣️ Great video! Clear instructions with easy to follow directions. Thank you for sharing 🙏🇺🇸

Thank you. This helped me install a new regulator quickly and answered all my questions (teflon tape, reusing old joints).

Thank you- you just saved me $700 that my plumber quoted me to replace this.

Great video and i like how straight to the point that you are.

Thankyou, you and i have the same problem, I didn't know about it for years now. My heart sinking thinking about a 300-400$ plumber bill. But i think i am going to try replacing it on my own.

Thank Phil for uploading this video. I just fixed mine by following step by step your video, saving me a lot of money. 👍

Just got mine replaced, no problems. Thanks for the video Sir

So when a plumber says this replacement will take 3 hours, I’m assuming I’m being taken advantage of? You sure made this look timely and easy. Thanks for your video.

Thank you for this. I really like the suggestion of getting the same dimension/identical pressure regulator as a replacement so I don't need to solder or clamp any fittings. I think I can do this now (just hope the existing 30+ year-old nuts are not too far gone or rusted)!

Thanks for the video. I checked with a local plumber to replace my regulator valve and was quoted between $275 to $395 depending on location, pipes, etc. GOOD GRIEF !! Think I'll try it myself. My plumbing projects in the past usually take much longer than expected and quite a few trips to Home Depot or plumbing supply. Fingers crossed.

Excellent tutorial. I'm going to attempt this today. My water pressure (in the whole house) has been dropping over the last few days. Can this also be a symptom of a bad regulator? Your video gave me hope that I can do it myself. 👊 Thank you.

nice vid and simple DY install. the only vid i found on youtube with my actual set up with the main valve in the house and not on the street so thanks on my way to home depot to get rip off for the regulator .

Thank you. Saved me a couple hundred bucks.

Great video.. simple and to the point.. Thank you

Great explanation!

Thanks so much saved me a ton of money. Unfortunately my new one only came with one O ring (what gives there) so I had to reuse the other ones.

Thank you very much sir.. I’m gonna try to find a new valve and replace mine.

Thank you for sharing your skill and knowledge. This is a great video. I have the same bad pressure regulator, but could not get the equivalent part from Watts. They just offer a smaller device that requires pipe work for installation. May I know which equivalent part can be used as a replacement without the need of pipe work as shown in this video?

Thank you so much for this patient, clear, detailed video! Is it possible that a 19yr old PRV can just be cleaned rather than replaced if water pressure has gone down significantly inside? Also, a plumber wants to charge me $650 to replace! Thanks again!

Thank you so much for this awesome video

Nice video, just remember the shut off valve should always be before the regulator.

Do you put any kind of lubrication on the O-rings?

This is very good info where do they sell the water pressure gauge at

Great video! Saved me $500

awesome!!!! thank you for sharing! i just followed your procedure and walah!!!!.

Great instructions! Very detailed info! can any brass prv be use on a pvc pipe? I have never use a prv brass valve on pvc pipe I was just wandering! Thank you 🙏

Clear concise video A big help TY

My PRV has a *very slight* leak. I mean it leaks like, maybe 1 or 2 drops every few minutes. The source of the leak is the pressure adjustment screw at the top of the valve. Do I just need to tighten it, or is there a gasket inside the body for the adjustment screw and nut?

Curious why you went directly to replacement without adjusting the old regulator first. Thank you

hi..I have the same model valve from watts however they have discontinued this product .what alternate model can i use its 3/4 inch.tks

Great video sir! I got a strange mystery if you don’t mind. I rebuilt my water heater, elements, thermostats, and thermal expansion tank. Everything installed like a dream, and correctly down to the letter. Except now, it’s like there’s a pressure build up. When I turn on the faucet, bathtub, shower, there is like this quick blast of pressure for a split second, then normal. Why is that happening? I matched the 80 PSI of my water pressure to the thermal expansion tank.

Nice tutorial! Can you tell me whether this regulator is silent or clicking while working? Tank you

Good trick on pressure gauge to h2o faucet.

I have replaced with similar to old one but there is no water in mains

Great video!

Omg this was a life saver

Very good video. Thank you.

Nice 👍

What led you to know to replace it besides the pressure been to high? Does high pressure on the gauge make water out your lines come out with high pressure or low pressure? My house seems to work only with one line. Plbut if I’m washing dishes and washing my hands in the bathroom the pressure seems to go away. My lines copper lines are not that old.

Well done! Thanks 🙏

Question if I may… can you use a prv on a 40 scheduled pvc? Appreciate any input! I’m in Las Vegas and from the street supply line there is pvc scheduled 40 no prv valve. Thank you?

About how long will it take to drain all the water from my houses system? Quite a while I imagine? All water both hot and cold has to be emptied? I have heard emptying the hot water heater tank fully can potentially cause problems, am I misinformed? Should the water heater be turned off while I do the install?

Nice tutorial

What do you think is wrong if I adjusted my water pressure valve and when I loosen or tighten it the water pressure according to the test gage doesn't do anything?

Great tutorial! Just wondering what prv replacement valve model did you purchase?

most excellent, thank you!

Thank you for this video. I just found out today that my water pressure is very high and need to change my regulator... is it advisable to drain a lot of the water from the whole system before opening it or can I just close the valve between my softener and heater and drain that pipe to accomplish this task? thanks in advance.

We have a home warranty that is covering the valve, but the plumbing company is charging us an additional fee for a water line modification that they say is needed to put new valve on. Does that make sense?

Thanks for the video👍👍🍺🍺

Good video...thank you.

I'm doing a new install. How much pipe should I cut exactly? Is there a margin for error when cutting. I fear I'll cut too much and bring on a huge chunk of additional work to undo the damage.

Is there a rule thumb for how much adjustment should change pressure? (For example 1 turn would change 10 psi)

Thank you so much!

I have a question. How do you know your regulator broken or doesn't work? I did adjust my regulator but its seems doesn't effect. Please let me know. Thank you.

Can I convert an existing sweat valve to compression valve or push in valve? Thanks

What type of connection is that crimped onto the pex? Is that a flare connection that is required with this type of regulator?

Mine has been baffingly built into the wall with only the set nut on top of the regulator sticking out. SMH!! I'll start with getting a pressure gauge before I start messing with my pressure (that's too low for my preference). Is there such a thing as going too high or will the regulator itself keep me from damaging anything with "too much pressure"? Thanks!

Thanks for the great video! I have a new PRV installed but when no water is being used in the house, at times, water drips from the top where the adjusting screw/jam nut is. Does this mean it’s a bad PRV? Looking at the cross section of the PRV, it seems no water should reach the top part given the diaphragm should act as a separation barrier. Thanks!

Does the regulator act as a shut off valve as well? My water heater is leaking. I want to drain it but not shut off the house if possible

My house has the regulator before the valve how would I remove in that case?

My house is 6 years old, and I am being told I need to may $350 for a new regulator. Is this common? Seems pretty simple to install.

What's the name of that PEX adapter that's clamped on? I'm want to do the same exact set up

Mine seeps when I first turn the water on then stops after some time not sure why

I tried it all the way clock wise and all the way counterclock wise. all same reading at 140 psi!.

Wait where do you find it first of all? It does not show

Great video, however the pressure regulator should be installed between the water and the outside of the house...NOT permitting the 120 psi pressure to be INSIDE the property whereby the connection to the pressure valve could rupture - causing a fatal leak (flood) inside the home. Additionally, the water pressure above 40 psi will damage all O-rings & gaskets in the faucets, fixtures, shower heads and washing machine. It should be adjusted to at 40 psi maximum to avoid surprise leaks when the homeowner is either IN or OUT of the house. You can also purchase the pressure regulating valve with a lower setting (not to have have to adjust it quite so much). For example: 20-40 psi or 20-60 psi. They're also less expensive.

Man I owe you a beer. Followed your instructions and installed it with no problem. Saved me money and no more wife nagging (at least not about that :) lol

I was curious what would happen if a pressure regulator was installed backwards?

ok do the same video with female ends on the water reducer, with copper pipes

@philcrockett do you kick breaker on hot water tank while installation

Hi Phil. Great video. Wanted to ask what you charge for replacing PRVs? I’m trying to price jobs accordingly to be fair with my customers and myself. Thanks buddy

What I cannot find on RU-vid is any instruction for cleaning or maintaining a PRV. I only find instruction for replacing them.

Is it ok if my valve only came with one o ring ? And the last one I took off has a different design

should I turn the water heater pilot off. the water will be very hot if I don't right?

Does the water regulator need to be installed in a certain orientation?

Should my valve moves little after tightening it ?

what is the expected lifespan of these? thanks!

Where can I find it in what part of the house

nice

120 PSI won’t hurt anything so why not just leave it

No ones house look like that underneath.

Or it could be an expansion tank gone bad

70 psi
