Great video👍 I'm glad I found it. My water pressure seemed to be too high. When I cut on the kitchen faucet it beat down on the stainless steel sink basin like a bullet.. I also have that plumbing in my house that is prone to leaks.. I figured this would help it as well if I reduced it some.. I have a pressure regulator like the one listed on this video.. I ended up turning it counterclockwise about three times.. I didn't know about that lock nut as well.. That was a good guide in letting me know how much I had reduced the pressure.it is much better now. Thanks again for your very detailed and easy to understand video. The next time I have a plumber in I will get him to check the pressure as well.. I didn't want to spend $150 just to get it reduced to about the amount that it is now..

I've always been frustrated when I washing my car or even taking a shower with the weak water pressure. So I did what you said crank the bolt down a little and I'm so happy now it takes half the time to wash the car and to shower. Slightly concerned that the PSI might cause damage but I'm willing to take the risk, I don't have a gauge and all that mess. But to be honest with you it's not that strong of flow like at the kitchen sink, it's not splattering out or nothing so I think we're probably good.

[@stompthedragon4010]

@@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.

[@Know-How-Now]

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.

With a Watts "bell-shaped" pressure reducing valve that's probably been in place for 15-20 years, if we assume parts have hard water calcification, etc, is there any extra precaution to take when trying to adjust? And are the Zurn equivalents (Zurn claims it has a cartridge design that's easier to swap out for maintenance) just as good as the famous Watts PRV? Thanks @KnowHowNow for your great videos.

[@Know-How-Now]

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 kzbin.info/www/bejne/gXuUfoWbibBqfaMsi=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.

Will the bolt adjuster in a pressure regulator valve come out if you turn it too many times to reduce water pressure? I need to turn my pressure down but I am not sure if the old regulator is working or just has been turned up too high previously.

[@Know-How-Now]

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.

Hello, great video!! Have a quick question, why do you have to tighten the lock nut when you are done making adjustments? My pressure is at about 60 PSI and that is fine for me and my house. But, every time I tighten the lock nut at the end, then turn on my faucet, I get a slight water hammer, why is that?? Did I do something wrong? I followed your video. I have no expansion tanks in my house. Does this mean I have an open or closed system?? To solve my water hammer, I loosen the lock nut just a little bit, water hammer is gone. Why is that? Please let me know. Thanks, Jeff

[@Know-How-Now]

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.

[@Nnon11026hj]

Hi, have dumb question. I guess I have closed system since I have thermal expansion tank which I don't know what the pressure of itself is. And I just had PRV valve replaced by the plumber and connected the pressure gauge to check the water pressure. The pressure is set at 60psi however next day when you check the pressure the the black needle and the red needle are both at around 100psi.. and when you use the water, the pressure drops to 52 and goes back to 60.... not sure what is going on here....

[@Know-How-Now]

It sounds like when your water heater turns on the pressure is running up due to thermal expansion. When you open a tap it is releasing the pressure. I would guess that your expansion tank may be bad. They have a bladder inside that can fail and fill with water instead of air/water combo. I have a video on how to check the water pressure which you might find helpful, there is also another video that explains how this type of system works.

[@Know-How-Now]

Thanks for subscribing. No, I'm not a plumber, but enjoy understanding how things work. I'm not well versed on boilers. If the water pressure is running up and you have to open a tap for it to get back down to around 60, then I'd think it is caused by thermal expansion/heated water. If it is a closed system, then you need some sort of expansion tank to keep the pressure low when water is heated. I'd call the plumber who replaced the PRV and quiz him about the high pressure problem.

My basement utility faucet was replaced recently and began leaking from the spout a week or so later so I thought the new faucets parts couldn’t be causing the leak. I asked around and was given the idea that the water pressure could be too high, which made it start leaking. Do I need to shut the faucets water supply off before I can try to use your video to reduce the pressure, or turn it back on?

[@Know-How-Now]

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

On the main water valve (located closest to the water meter), should the ideal setting be turned in full open setting all the time? ...and then set the water pressure? Tnx

[@Know-How-Now]

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.

[@mr.c6674]

I changed my gas water heater and now do not have water pressure. My setup is the same as you show in the video (the bell shaped reducer thing). I turned off the city valve and the one after the city valve. The water heater is now installed but I'm getting a PSI of 10 or less. Was I supposed to adjust the pressure reducer/regulator? I've never touched one of those before so I'm not sure what to do. Based on what I've read on the internet so far I believe so, but I'm not confident in the process. Thanks for the video

[@Know-How-Now]

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?

[@polocash11]

Should I put in ground after turn off valve to whole house or just in the garage that feeds the the inside plumbing? And I think I want one with a pressure gauge included to check from time to time.

[@Know-How-Now]

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

[@polocash11]

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?

[@Know-How-Now]

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.

My gauge reads my in home pressure fluctuates 52-56 PSI. The manufacturer sticker on the thermal expansion tank states "pre-charge pressure" of 40 PSI with max pressure 150.Of note, the gas water heater and thermal expansion tank are original and close to 30 years old, but still no leaks or related issues. I'd like to turn the whole house up to about 64-68 PSI as, currently, when any tap is opened, the pressure drops to 20 PSI. Thanks!

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.

how far out can the valve come out? we got ours down to 75psi, but i'm afraid to turn the screw any more. (it was 110psi)

[@Know-How-Now]

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.

A few months ago I may have adjusted our pressure regulated valve without loosening the lock nut. Any chance I damaged it ??? Great video thanks!

[@Know-How-Now]

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.

Hey, great video. Quick question. When adjusting the pressure through the Pressure Regulator Valve, do you have to turn off the main water supply that feeds into the valve, or is it OK to leave the water supply main on, while adjusting the PRV? It's a bit of a pain to turn off the supply, adjust the valve, then turn it on again, just to see if the pressure adjusted to the desired level..

[@Know-How-Now]

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

[@desidhamaka9022]

@@Know-How-Now Thank you.

[@Kcwaterheaters]

The PRV makes it a closed system.

[@Know-How-Now]

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

[@Know-How-Now]

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

[@Kcwaterheaters]

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

[@Know-How-Now]

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.

[@Kcwaterheaters]

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.

[@christ2551]

Great video ! I tried turning clockwise and counterclockwise on my Wilkerson water reducing valve 70xl. However the water pressure reading is the same at 120 psi. Does that mean the regulator is broken and needs a new one ? Am I doing something wrong?

[@Know-How-Now]

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: kzbin.info/www/bejne/gXuUfoWbibBqfaM

[@christ2551]

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

[@Know-How-Now]

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.

[@christ2551]

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.

[@Know-How-Now]

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.

Counter clockwise to *reduce* pressure; clockwise to *increase* pressure.

I do my best to not waste your time... I doubt you want to watch water run for 30 seconds. Someone would be howling about that in the comments.

[@woodmaker1]

The water co. Told me to turn to thr right to decrease the pressure and left to increase..who wrong ???

So far, no one has commented that I am telling you to turn it the wrong way.... the videos has thousands of views.
