How to Test Water Pressure at Home (and Adjust It Fast!) 

Thank you so much. I was able to check the pressure and lower it myself. I especially liked the recap at the end.

Just wanted to mention that your backyard is beautiful! Thanks for the video. It was very helpful.

Great video, very informative for someone who didn't know anything about this!

Excellent video, very helpful!!!

Wow-- so well explained, Dino! Your's is without question the BEST plumbing-related video I've seen all week!

Thank you sir. Very helpful.

Thank you so much for this video!!

Thanks! That was helpful! I need to add, that when you want to lower the pressure, you will have to turn on the water somewhere in the house after adjusting the screw. Otherwise you won’t see a change on the gauge. After releasing the pressure it will settle to your new set pressure 😊

Thank you - this was a big help! Very detailed but not long and tedious detailed.

Great Video + info. Thank you. Had my mom's refrigerator water line valve start leaking, got it replaced, then found the refrigerators water valve was leaking way worse too. I was wondering what would cause both to go at the same time..... All I could think of was too high of a water pressure..... So I needed to look into checking it myself. 1950's house, (some) new lines, 18 year old fridge, has been too many half a** "plumbers/workers" worked at my mom's house, along with other problems too, and ....me.... Sadly with very little knowledge of those things. So,.. I figured I'd give some things a shot. Can't/Shouldn't do any worse than the people that were hired. Lol. Thank you. I appreciate it.

Nice presentation and thanks for sharing.

Very simple and informative. Thanks for sharing.

Thanks for the great video. Is the pressure the same for pex water lines? 👍

This is very helpful, thank you!

Thanks, this was great information!!👍🏼

Thank you so much. Our garden hoses kept bursting. I have tried everything. So now I have lowered the water pressure & hope that solves the problem.

Hello, thank you for your video! Very well explained! Currently my house has a water pressure of 100+psi and the plumber is recommending replacing the PRV. Instead of replacing, can I adjust the pressure on it so that it's around 75? The PRV might be around 15 years old though. Thank you!

Thank u very much Sir..u test out side, but my kitchen sink has horrible pressure but basement sink super pressure..by testing outside is there a reason for where u put on the tester?

Great video very well explain, I thank you!! my water pressure is fine and so is my "Blood Pressure" I`d twice busted pipes.

Great video

Thank you thank you!! Our water pressure got turned up to high by the people doing our water softener sysyem and i was able to fix it myself! It was actually 10 over recommend on our tag

Can water pressure be checked from hot water tank drain valve. I was told to check pressure just like you showed in this video

Thank you. Our pressure adjustment unit is new style, then the screw driver dent knob is pretty much worn out. I was able to use a wrench and adjust this time. I may change the unit when possible...

good quality video and audio. what camera is this?

very informative. bardi HVAC came out to do a "complimentary" plumbing inspection. dude tried to charge me like 700 bucks to adjust the water pressure. man these people are INSANE

I see that you reply back- good, so my question is that I live in an apt./condo ( I own it) and we had to all change our water tanks. I have the expansion tank and a brass "t' valve for the expansion tank. To put on the tank I have to know the water pressure to correctly hook up the expansion tank so how do I go about this being that I do not live in a house like you show but live in an apt building and so l can not tell all the tenants not to use their water just so that I can test my water pressure. We do have the relief valve going from my water tank to the outside of the apt. just so you know.

Thank you. I have had to learn how to be independently proactive in caring for my home. Your instructions were very clear. I am right at 60 psi. Very empowering. How often should I do this?

Thank you for the very nicely done video. I have one question. Some of the other resources I have read recommend shutting off the water main. Should I do this?

Thank you.

Shouldn't you loosen the lock nut on the bolt before adjusting the pressure and then tighten it again when you're done?

Hi Dino, how do I find the water pressure in my closed hydronic heating system? Thanks.

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.

Excelente!

How come you didn't loosen the bolt below the bolt that lowers and raises the water pressure? Do you need to shut off the water main before you adjust the pressure? Thanks!

Thx, helpful

How do you check the pressure in the bath tub where that won’t fit on it. The outside faucets have good pressure. Inside the kitchen, washroom and bathroom not so much. How do you increase the pressure inside the house?

He forgot to mention if your water pressure doesnt increase after turning the head of the bolt clockwise, you need to replace that regulator since it's bad. Usually after 20 years. it needs replaced. The new water regulators come in 5/8 inch and 1/2 inch for home use. They run about 100 + bucks. ( as of this posting 3-13-2024. )

Our pressure had always been very low. It only became an issue when there wasn’t enough pressure to flush my boat engine. So I tested it and it was at 20 psi. I adjusted it to 60 and now the engine is discharging with the hose just fine. Anyway, should I adjust it back down? Or do I need to worry about it spiking and becoming too high? I just don’t want any leaks with too much pressure. It’s at 60 now

My adjustment runs right into my water softener, does that change anything for me when adjusting my pressure?

Thank you very much, helpful, will help me check my water pressure and if, necessary making recommended changes.

I bought the same gauge and my pressure was 105. My house is only 4 years old though. I guess I need a pressure regulator?

Hi there. Question. My water pressure is awful. Inside my home I did the test at the faucet, timing how long it took to fill 1 Liter. It took 30 seconds to fill 1 liter. The instructional advice was that it should take 6 seconds to fill 1 Liter. I do not have that bell with the adjusting bolt inside my home to adjust the water pressure. I only have the water shut off valve at the main coming into my home, in my basement. Should I have one of those bells put on? The other thing is the city has the outside meter in my yard, set between 30 and 35 PSI. I understand it should be set on 60 PSI. Is there a way to increase the water pressure between that outside meter and my house since the city has it set so low at the meter? The water pressure often drops to 10 PSI, and lower, barely coming out and this occurs often, nearly daily. And it's caused me to even ruin washing white clothes in my washer with a little bit of bleach, and ive gotten very sick with stomach cramps, diarrhea and such as well, from drinking the water at such low PSI. What can I do? Thanks.

Great video but stuck on one thing.... which outside spigot do you attach it to? Like with most houses, I have two. One is closer to the intake, the other is on the other side of the house. The one closest to the intake reads about 55 on the black hand. The other one reads 85. Which do I go with?

What pressure would you recommend for a 27 yr old house woth pcv plumbing.

I attached the gage with nonwater running and received a 150psi reading. Adjusted the screw and nothing changed. I then turned on the faucet and reading dropped to around 35. Stayed around 35 but the faucet still sputters. Aside he sputtering the prv had a leak. Waiting a little bit before i go back to that part. I need to faucet 2 stop shaking 😫

What was the psi after the short turn?

Tried to lower the pressure but screw came completely off, can this be fixed??

Thanks for the video. What if the black needle shoots up initially to around 80 and then settles down to around 60 and stays there? Is where it stops the correct measurement? Thanks!

We have a toilet that when you flush it the water line for the fridge icemaker squeals while the toilet refills. The sink beside the toilet cold water nearly comes to a stop when toilet is flushed. The squealing noise isn't at the toilet though. It is behind the fridge. Brand new water regulator. I can't test water pressure this way because the outside faucet is before the refrigerator. I'm stumped.

Why does the pressure on my gauge jump way up when I first turn the water on, but almost immediately settle back down to about 50. I didn't see that when you first turned your water on.

Tfs this info, it appears my pressure needs reducing, my monitor says 100 and it looks like water has entered it! Can this be happening as a result from the underground water issues my property has been happening?

Well, maybe I should put in a PRV, I'm a little worried that water will be coming out of the sockets soon, the enamel tub is almost down to bare metal.........

Plumbing Theory Question: Would it be possible to isolate a section of baseboard to prevent the pipes from freezing by cutting in shut off ball valves where it breaks off the system at the supply, 1 where it joins the return, and spigot in the middle to drain the line after it's shut off? I ask because my house has an addition my parents put on when I was a kid and whoever ran the baseboard literally ran the supply outside the foundation of the house before going up into the floor of the addition.

My outside line branches off before my pressure reducing valve, how can i check my pressure?

Why does it have to be tested on an "outside" faucet?

With the shower on . Should the water pressure maintain the same pressure as if NO water is running ??

How fast should you turn ON the spigot or does it not matter?

Hi Tom, what happens if I have two different showers in the house, and one gets great pressure and the other one is terrible. I have removed the actual shower heads from both so there is absolutely no obstructions, and still it's the same thing. One has great pressure and the other one stinks. I've tried 4 or 5 different shower heads that are supposed to increase the pressure, but NONE of them have worked.

I checked my pressure on a outside spigot and it read 60. I then double checked it and it was reading 100. Am I doing something wrong?

I want to reduce the water pressure, if I keep on turning counterclockwise, will the screw pop out causing a leak?

Is there a maximum before problems arise? What types of problems? Mine just went UP. NO regulator to adjust.

What if the red mark reaches 140 immediately upon opening the faucet but the black mark stays at 70? Can someone help with this.

thx Dino this was informative and it helped me ........like 17 2 15 22 ........btw my brother's name is Dino .........glad I viewed this clip........Mark

This guy needs to redu this video. There is a big difference between outside pressure and in-house pressure.

I don't understand as the outside tap is before the PRV; so reducing the PRV did not change the outside tap pressure, which is off the mains?! so confused

Ha. I always thought you were stuck with the pressure you had!

And if your house lacks a prv, you need to call a plumber asap.

2:42 Did you really turn the knob the wrong way....

How do you know if you need a pressure reducer valve, the meter reading is between 50 and 130 psi

Best to perform additional research before trust of this singular approach

This is classic example of why it is important to contract/employ a professional/licensed/insured PLUMBER ... that is educated within the discipline of hydraulics engineering! Ha!
