@@Know-How-Now Hi! Brilliant video! However, I have the closed system you mentioned and would appreciate it if you could put up instructions on how to adjust. Also, could you make a recommendation for where to get a cheap pressure guage that I don't expect to use more than once? Thanks again!!

I have a video that shows how to replace a PRV. The end shows how I adjusted it. kzfaq.info/get/bejne/gbBhgLWWubGbd3U.html

You are welcome, Chris. Maybe the valve was stuck. I've seen small stones in water lines after repairs to water mains. The valve in the video has a screen before the "bell". Not all valves have a screen. Maybe you just had some dirt lodged in there. There are rebuild kits for the valves.

@davidgrayson9185 Isn't 120 psi considered rather high? Are there any suggested ranges of pressures beyond which homes with copper pipes (or, differently, PEX pipes) may start to experience damages to fixtures and pipes? Also asking @Know-How-Now

@@petatube120 is too high. Thus I had it replaced 2 years ago. As for psi ranges… I am the wrong person to answer

Thanks for the compliment. PRV's can make a noise, so can a loose washer on a valve. Best wishes for finding a solution to the noise.

@@Know-How-Now Thanks for responding. I do have one question maybe you could answer. I live in a mobile home park so I know we have to determine whether this is from my residence or the community lines ( they are often digging- up lines for repairs all over the patk. Water main breaks etc.) Of course I know when I am running water in my own place. I had a hot water line replaced this past winter. They had to come back to fix it a few months later. I know what the hissing from the heating vents sounds like and it is not that. I had not initially considered water pressure because I knew nothing about it. As you can imagine I was researching for answers. I had a new water heater put in a few months ago and after realizing it could be water pressure I realized that this awful noise only started a few months ago. Sorry for going on but was trying to give some background. Here' s the question: if in fact the noise is from my own trailer, would it be possible for it to completely stop for a day or two then start- up again? Because it has. Usually waking me out of a dead sleep and preventing me from going back to sleep. It will continue for days and then stop for a day or two then start again. Thank you so much for your time.

If the noise started soon after the new water heater install, I would call the installer. They may have a suggestion for you or may come and look at it to determine if it is a problem with the install. If that route doesn't work, I would talk to me neighbors to find out if they too are having problems to determine if it is just your home or many homes. Then I would start to log times and dates, duration of the noise and try to correlate it with something else that is happening at the same time. Water heaters do expand water when they heat it.... that means moving water.

@@Know-How-Now I just called the company again. The more I think about it the more it makes sense that that is when it started. I just didnt know enough to make the connection back then. Thank you so much.

You are welcome, I hope you are pointed in the right direction to find the solution.

You are welcome, it's my pleasure to help. Have a great day.

I just played the video. What I am trying to tell you, is that if you change your PRV pressure, you must also change the air pressure of the expansion tank. Sorry, I didn't realize that I was ambiguous. You may want to consult the installation instructions if you have them. You can likely find them on line or if the tank manufacturer has tech support, you could call them. There seems to be a lot of different opinions about correct pressure. terrylove.com/forums/index.php?threads/expansion-tank-air-pre-charge-pressure.3578/

You are welcome. Best wishes for rebuilding the valve.

I don't have any videos on expansion tanks. There are some debates on the correct pressure. It is common to set the tank pressure to match the house pressure. You may want to look up the make & model number of your tank on the manufactures web site. Often you can download the installation instructions if you don't have them.

You are welcome.

You are welcome.

To clarify, you are using a gauge to check the pressure? Some times a hose bibb is before the PRV, if yours it that set up, you can check the pressure before the PRV. You shouldn't have to do anything to PRV. Maybe some debris from turning the valves got in the PRV?

That's a complicated question, the problem could be poor design.

If you can't adjust the pressure to 80psi or less - no water running, there is likely a problem with the regulator. I have a video that shows how to replace one. Here's the link: kzfaq.info/get/bejne/gbBhgLWWubGbd3U.html

@@Know-How-Now Took apart the valve, and there was a bad o-ring. Fortunately, Zurn sells a repair kit for the Wilkins 600 series valves, and it worked. Thanks!!

Thanks for the update. It's good to know you were able find a repair kit and fix the problem.

There are so many valve make/models, I can't give you an accurate guess.

If the locking nut is brass, and the adjusting screw is steel, then you may have stripped the softer metal brass nut's threads. If the adjustment screw doesn't turn by hand freely, I wouldn't be too concerned. I'm sure the manufacturers put the locking nut there for a reason. If the adjusting screw spins easily, you may want to mark it and see if over time it wanders. If it moves on it's own, then maybe you can get replacement parts from the manufacturer. They do sell rebuild kits.

Not Likely 👍

Aa ❤😂as a a 😊weqq😊

Hi Jeff, the lock nut's purpose it to prevent the adjustment bolt from moving. It's just coincidence that the water hammer happens when you tighten the lock nut. If you are having problems with water hammers you may try doing some searching for information about them and their causes.

If it won't adjust, it is likely is bad. It is possible that some debris is stuck inside. Some models have a screen and clean out. The regulator in the video has a clean out. It's the cylinder on the bottom next to the bottom of the "bell". There is a nut that can be removed. Inside is a screen. If the regulator is old 10-15 years, then odds are that it needs to be replaced. Also, it could be clogged with mineral deposits. I also have a video showing how to replace a PRV : kzfaq.info/get/bejne/gbBhgLWWubGbd3U.html

@@Know-How-Now Your video was very helpful. Thanks! I posted a question on the other video. Will appreciate if you can share your feedback there.

Thanks for the compliment. I hope the repair goes smoothly.

Did you turn the water heater temp down? When water is heated, it expands and the pressure increases.

It's doubtful. If you have compression style valves, the washers on them (if they are damaged/failing) can make noises. There is a playlist on my channel that is all about water shut off valves. Click on the channel name and then the playlist tab.

When adjusting the PRV, you don't need to turn the water supply of to the faucet.

There is no precautions to adjust. If the pressure is low, try cleaning the screen. If it won't adjust, then it's probably bad, there are rubber parts inside that can fail. I haven't tried the cartridge design. Is there anyone out there who has tried them? I have a video that shows how to replace a PRV kzfaq.info/get/bejne/gbBhgLWWubGbd3U.htmlsi=y9V6_bXBvZunAJ8R

@@Know-How-Now Thank you for your tips! In my case, the old pressure reducing valve (Watts N35B, almost 30 years old) had hardly any response when I tried to turn the pressure down. Got it professionally replaced, with a Double Union connection so that future replacement of the valve is easier. When researching the brands, Watts and Zurn-Wilkins seemed to be the big names. Cash-Acme was markedly cheaper but I could not find enough reviews (or history/longevity) about it.

You are welcome. Good to hear you have resolved the problem. Thanks for following up with the details. Have a great day.

Thanks!

rgwater.com/why-does-the-water-pressure-change-throughout-my-home/

I can't speak for every model of PRV's, the bolt shouldn't come out. Get the model number & make, it's likely on a tag or stamped on the valve. You can look up the specs for it.

You're welcome

Sounds like an internal seal is leaking, Joe. I have a video that shows how to replace the valve kzfaq.info/get/bejne/gbBhgLWWubGbd3U.html

@@Know-How-Now Yes sounds maybe it. Thanks

If the main shut off valve is a compression style (it takes many turns to open/close), open it fully an then close about 1/8th - 1/4 turn. The position of the valve won't change the pressure, but it's good practice to do as described above when opening the valve.

I'm not clear on your question. Are you saying you have two PRV's?

Know How Now I don’t have 1 yet. My meter is in ground under a cover. After that I have a shut off valve under another cover. Then the pipe splits somewhere under ground to outside spigots and the other to inside garage. Then water softener and into house. Everything is threaded in garage so easy to install there. Outside would have to cut pipe and solder inline. If I reduce pressure in garage will that increase pressure to spigots? If only 1 PRV, where should it go?

Often, the outside spigots or sprinklers do not have a PRV. You likely don't need one there. The PRV should be installed on the pipe that feeds the house. I'm curious, why don't you have a PRV now? I don't know your local plumbing codes, bust most require a PRV, if the street pressure is greater than 80psi (for the house) you need a PRV. If you reduce the pressure in the house branch, it won't increase the pressure to the outside spigots.

@@Know-How-Now Thanks for the help. I am not sure why I don't have one, unless it was not code at the time. 20 yrs ago...... I have seen these range in prices from $25 to over $100. Should I get one with a meter to see pressure anytime, or do I need to put in a T? Since my pipes, in garage, have been changed to 3/4 copper threaded, I would like a model that would just screw in. Can you give me a link for a decent one?

Watts & Zurn are reputable brands. You can go to the websites to find the specs for the models. If you have questions, I know that Watts has tech support. I can't be sure to tell you the correct model for your installation from "the arm chair".

There are too many variations of valves for me to know how far out you can turn yours or if it has a stop. I suspect that yours may need to be rebuilt or replaced. There is likely a tag or a label on the valve. It will state the range of pressure. Mine says 25-75lbs. The 110 lb reading is likely over the range of the valve, indicating that it is not working correctly. Also suspect is that you can't get it below 75lbs. In most cases, they are not that hard to replace. (I have a video that shows how to do it.) If you choose to replace yours, make sure you buy the correct PRV for your system. If you are confident that the one installed is the correct one, you can likely find the same model and just swap it out.

I can speak for every valve, but it shouldn't pop out. Make sure your shut off valve works. You can do damage control quickly if someone actually made that dumb of a design.

if it has a return line then it would be a hot water heater hehe

Are you saying that the plumbing company has left you with a broken PRV? What was the initial reason for calling the plumber? Did the plumbing system ever work correctly?

There is no need to close the main water supply valve while adjusting the PRV.

@@Know-How-Now Thank you.

You are kidding me.

I'll have to politely beg to differ with you. The PRV shown in the video is a Watts LFU5B-Z3, it has a bypass, so this system is not a closed system. Here Is the link to the spec sheet on the valve: www.watts.com/dfsmedia/0533dbba17714b1ab581ab07a4cbb521/20423-source

PS - I checked out your videos. Nice job. I really liked the one on warranty heads up.

Yes there is a bypass but a PRV is typically installed where the pressure is higher on the opposite side of the PRV. Water will not move through the PRV bypass until the outside city pressure is exceeded. PRV = closes system Also the bypass gets blocked/clogged frequently

I tested the new PRV I installed, when I tripped the water heater, the pressure reached the street pressure, the bypassed opened and allowed the water go back into the municipal system (Just like an open system). I watched it happen on the gauge. There is no expansion tank, it's an open system because of the bypass in the PRV. The old PRV had been installed at least 18 years. The bypass never clogged. I took it apart. The gasket on the valve failed, no evidence of any clogging.

Know How Now “when the pressure reached the city level the bypass opened” lol. The pressure inside the home rising up to the city pressure is a result of Thermal Expansion. Maybe you should give me a little credit, I’m a licensed plumber certified in fuel gas. I do this everyday, you are spreading misinformation.

If it won't adjust, it has likely failed. If it has a strainer/screen, you can remove the plug and try cleaning the screen. There are rebuild kits for some of the PRV's, but that means you have to turn the water off for a while. It's probably best to just replace it. You could buy a rebuilt kit for the one you took out and then keep it for the next time you to replace the PRV. I have a video showing how to replace a PRV: kzfaq.info/get/bejne/gbBhgLWWubGbd3U.html

Know How Now is it Universal that regardless what brand, turning clockwise will increase pressure and counter clockwise will reduce pressure? Thank you!

You can likely find the installation instructions on the manufacturers website for your model to verify the turn direction, though if it doesn't adjust then it's not working. You should see some sort of change with just few revolutions.

Know How Now thank you. From your video it seems like you implied that counterclockwise will reduce pressure and clockwise turns will increase pressure. I did not know it is brand specific.

I can't speak for every make/model, there is a chance that there is an odd ball out there. Also, I am assuming you are looking onto the top of the adjustment bolt. Again, if it doesn't adjust, you likely need to clean/rebuilt/replace it.

Thanks

I can't speak for every make/model of PRV. Allowing the bolt to turn out would be a bad design. If you are turning the bolt and it's not changing the pressure, then it's likely the PRV is bad.

@@Know-How-Now ..I was asking about the model orb you were showing. You reply is not making sense. Can the bolt come out or not if I turn it too far ?

The gasket has failed.

@@Know-How-Now is there a solution to that

Replace it. You might be able to find a rebuild kit, though they are often expensive.
