How to adjust & measure home water pressure

[@declanconnelly6699]

Thanks for the video. I had a plumber come to check my water heater. He actually turned up the water pressure to 95PSI and then told me I need to spend $1000 to replace the pressure regulator, in addition to $5000 to replace the water heater. He said he tried but was not able to adjust the pressure lower. After he left, I noticed the shower pressure was extremely high. I figured out how to adjust it and it's fine now. Gotta be careful with these Plumber scams!

[@joemendoza2292]

$5,000 to replace a water heater? Report that scumbag to your local city hall immediately and get his contractors license revoked.

[@Rangyroth4089]

Yeah 5000$ for a water heater was your 1st sign That shouldn't be much over 1000$. I had mine changed for 1000$ total.

Thanks SO MUCH! After I bought my home I was determined to have my dream refrigerator...REAL stainless steel Frigidaire Gallery Professional Series BIG side by side. Abt a year or so later my ice maker quit working. It was still under warranty from Sears. I was a under 30, a single homeowner & I'm female. I'm also the daughter of a former steamfitter who taught me how to do everything he taught my brothers. I did everything I was supposed to do. It was just a bad unit & needed to be replaced. The guy came from Sears & 1st tried to tell me I broke it & it wouldn't be covered. I KNEW I DIDN'T & it SHOULD & WOULD be covered. After he knew I wasn't budging he then went down to my basement & after several mins came back up & turned on my kitchen faucet. He rudely shouted @ me said "SEE?! :LOW WATER PRESSURE! YOUR PRESSURE VALVE IS BROKEN, WARRANTY IS VOIDED & YOU'RE PAYING FOR THIS!" He demanded over $500 for my new ice maker & the service call b4 he'd even order the replacement. I was so perplexed, ticked & a little scared but tried to keep my cool. Standing in my suit & heels I blurted out "Hey buddy, don't let the blonde hair fool you." That caught his attention. I had amazing water pressure before he went downstairs & told him so. Also told him my father, IQ of 165, former youngest foreman steamfitter, now President of a nationally successful automation company he started himself not only put in my hot water heater but my faucet & sprayer too & it was powerful before he came to look @ my ice maker...bcz it was...my dad would always joke how much stronger it was than his own. I asked him if he'd like me to call my father so he could tell my dad what he told me. He declined & the warranty covered it. I was so rattled & didn't know what the Sears guy did but knew he did something & also bcz I thought Sears would never be ok w/their employee doing that. I was young & naive but I know now THAT was part of his job. He JUST adjusted/lowered my pressure. I bought a new PRV & was going to learn to fix it but life happened & then my dad was in a fatal accident & water pressure was but wasn't high on my priority list. I still have the awful pressure & it's messing w/my Whirlpool fridge's ice maker & it brought it all back along w/the sadness of missing my dad...but YOU just taught me how to fix it. I'm sorry I am being so longwinded but I needed you to know YOU made a huge positive impact on my life w/your video today. You are AWESOME! I sincerely thank you from the bottom of my heart! I know my dad does too!🙏😇

[@pauldemore1043]

Easy to follow. Your video helped clarify exactly where I could test the water pressure and where and how to regulate it. Exactly what I was looking to learn. Thank you for taking the time to make it. Much appreciated.

[@LittleMogwai]

Adam, you may want to mention to the people that Have a Thermal Expansion Tank on their system that when you adjust the water pressure in your water system that you also have to adjust the air pressure in the expansion tank. The two pressures must match for the expansion tank to work properly. This is a good informative video. Thank you for posting.

[@AdamDIY]

Great point Roger. Thanks for the comment!

[@SC_RC1478]

What happens if you adjust the prv but not the expansion tank? My prv was an issue (psi went up to 100) and it was just replaced under warranty, but ive noticed the psi increases throughout the day or early morning hours. At one point, it got back up to the max prv level of 75, but it was set to about 65...so its fluctuating anywhere from 5-10 psi When plumbers came to troubleshoot the psi and when they replaced the prv (and adjusting the psi after the prv replacement), they never adjusted the expansion tank

[@LittleMogwai]

⁠​​⁠the air in the expansion tank is extremely easy to adjust yourself with a simple bicycle pump that has an air gauge attached to it. But be careful. Because I do not know the max air pressure of the expansion tank. You will have to do your homework on that part. My water pressure and expansion tank are both set at 45psi.

[@LittleMogwai]

Just a footnote. If you try to attach the bicycle pump to the expansion tank and water comes out, that means the air bladder inside the expansion tank has gone bad and you will have to replace the expansion tank.

I'm a Kiwi living of the grid. My water comes from a storage tank that is feed via the roof from rainwater.

My hot water cylinder has a tap but it does not have an out let like yours. God knows where the hose joining the tap goes to perhaps outside, that being the case then ya it would be like your used to drain sh?? from the cylinder, but then to confirm this would be a test in its self when I know there is no way one could crawl under the house to check. I like your video and will test things my way as ya my hot water is almost none existent when it comes to showers. Takes much time just to wet the body let alone to wash :).

[@whocares0316]

Excellent tutorial.! My pressure regulator is a Zurn Wilkins and it has no screw driver type slot to adjust the water pressure.Only a xex bolt on the end. I guess i just hold the inner bolt nearest the valve with a wrench and just use another wrench to turn the bolt clockwise to increase the water pressure?

[@Posttronic]

Thanks Adam, I suggest that you mention the physics of liquid pressure in a closed system (no escape), is distributed equally through the system to the farthest point and in all directions. When a faucet is opened, the system is no longer closed, and the pressure will drop and I would expect the regulator to compensate to keep the pressure close to the adjusted setting. Mine drops from 60 psi closed, to 40 with a faucet open. I was hoping to find a hint as to how much of a drop can be expected. I would guesstimate that nearly a 50% drop indicates a malfunction of the product. Think I may have to call Watt Customer Service for the info; not having much luck on the web. My source psi from the county is 150psi which kicks of the relief valve on most water heaters, interesting.

[@davidgoodson8203]

This was perfect man. I know nothing about this stuff and 2 years ago in my condo I did the exact opposite thing and broke my PRV and $600 later the plumber fixed everything. I used your video tonight and adjusted it in my new house and it worked perfectly. Thanks so much for doing this.

excellent. I have one question how do we define one turn i saw it looks two turns each time. i have recently changed the regulator the pressure was almost 90. the plumber who changed set the new one at 65 psi but pressure is very low in the second floor shower head

[@AdamDIY]

Zainab Muzzafar If it is only your shower that is low pressure and no other tap in the house is low pressure then you have a problem with a clog in the shower head or the shower valves. The head is easy to unscrew. Take it off and look inside the shower head inlet. You may see a filter or some debris blocking the flow. If you are sure it's not your shower head then you will want to look at the valves.

[@zainabmuzzafar9359]

Yes, the low pressure is only with the shower. Water is flowing quite fast from the spout. The sink faucets in the washroom and kitchen are also fine. Many thanks for the advise, Adam. Will try to work on it according to the guidelines you gave.

[@AdamDIY]

If you take off the shower head and turn on the water you will see if the water flow is still bad. Then you will know for sure if the problem is the head or further back.

[@zainabmuzzafar9359]

In case the problem is further back, I'll then have to call a plumber. Will that be a complicated issue?

[@AdamDIY]

Zainab Muzzafar Not too bad. Depending on the brand of your shower faucet you may be able to get the replacement part for free. You may just need to replace the cartridge.

[@zainabmuzzafar9359]

Okay, thanks again so much for helping, Adam.

[@F18Skyhawk]

Thank you so much!! Had a pipe burst and the regulator was turned way up when they were trying to shut the water off which resulted in the water pressure in the house being way too high. The adjustment at the pressure regulator is counterintuitive, you would think turning it clockwise would decrease the pressure. I found one of the gauges at Home Depot and I used it to adjust the pressure down to 50 PSI.

[@alecwatson9367]

Hi, I have a pressure reducing valve as part of a Navien combi tankless water heater. There is also a pressure relief valve. The tankless needs to be less than 30 psi, otherwise the pressure sensor is constantly leasing pressure. I want to know if I can reduce the pressure to stop the constant release.

[@shepherds_grandma]

Thank you! My pipes stopped vibrating with just one counter clockwise turn. I will have to get a gauge to confirm the pressure.

+AdamDIY Great video. I have a 15 year old house with a 6 to7 year old Watt LFN35BZ3 showing a 30psi. The area we live in has high alkaline in the water.This is the 2nd regulator as the first was replaced by the home builder while under warranty. My Questions: (1)You have any thoughts on water quality and its affect on these devices? (2)You think it might just be a matter of getting a pressure gauge and adjusting my pressure up, to say 50psi? (3) The pipes don't "hammer" s and bang,when turning on, particularly from outside locations, but the pipes do a type of singing/high pitch humming sound, regardless of flow rate(up or down at the wall) from the street to the regulator. Would that still come under "hammer" problems?

[@adeaths1]

would one shut off the water from the main line when adjusting the water preasure on the reducer valve

[@ninasloan8825]

Yes, this was helpful thank you. We learned that the pressure coming in to our house was over 115 psi, after a newly installed extension tank to our water heater was no longer working. The same plumber installed a pressure reducing valve like you have shown. Seems to me one could or should have been installed with a gauge on it, though it would have to fit behind wall paneling without protruding beyond the pipes. It seems odd that one wouldn't know how much pressure is added by just turning the end screw blindly. Any thoughts about this? Your easy solution of using a separate pressure valve would solve my asking him to change it out for one with a gauge. Thanks again for your good information.

[@AFsaps]

Adam you are from heaven sir. We've been dealing with low whole house pressure since we moved into our home. It took longer to watch your video than it did to fix this problem.

[@richardwinkler7822]

My plumbing looks almost identical to your video except I have a double check valve leading to the house fire sprinkler system. Also, I have a permanent pressure gauge near where the sprinkler drain line is located. This gauge reads 150 psi (not controllable by PRV since it's not in that part of the line) . I bought a gauge like yours and checked pressure at a hose connection and at water heater drain connection - both read about 105 psi. I did all this because we had a recent violent pipe rattling when both washing machine and shower were in use. I discovered that the water heater expansion tank diaphragm has broken. (A pressure check at bottom of tank emitted water instead of air.) Our water pressure does not seem extreme, but it sounds like we need to get it down to a maximum of 85 psi.

[@lesliesshopofcuriositieswo2092]

Thank You! I learnt more then I knew.

[@Gsxrtrix]

I’ll tell you this. I increased my pressure over 70 psi and you gotta be careful. All the toilets and sinks and various connections seem to break faster and/or eventually leak. Pressures regulation is safer at default levels 45-50- I think out of reducer. The cheap toilet components and cheaper seals now days don’t seem to like higher pressures. Basically you’ll risk popping lines and instigate a flood. As me how I know. And when insurance companies come in, they check to see if you played with it as an excuse not to pay a claim. Just a heads up.

[@truth6600]

Your exactly right 60 psi is fine,the higher the pressure more water you use,water hammer can start and I've seen water heaters work backwards, not one of these guys factor in thermal expansion.

[@GeorgeSawtooth]

If you have a thermal expansion tank on the water heater be careful with bumping up your water pressure as you might cause the pressure relief valve on water heater to leak. My expansion tank was installed horizontally and there is no room to allow me to add air to expansion tank due to a wall in the way.

[@fortunatedad7695]

You should be getting the same water pressure in your hot water tank as your hose bib. That drain valve probably is caked full of calcium restricting the flow. Put the gauge on your washing machine outlet. 👍

[@utoopuser]

This is a good video. I would like to add some comments. 1. The water heater is connected to the cold water at all times so the pressure is the same with no flow condition. 2. The pressure reducing valve also acts as a check valve *). The PRV shuts off when set pressure is reached and it does that with a rubber washer just like a faucet. Faucets will leak eventually and so will PRV's, causing the house pressure to creep up slowly. I have fixed them frequently but it's a pain. A new one at HD is about $100.- . From. China. for about $15.- , better build and easier to fix. (And it includes a gauge!) 3. After using hot water, cold water will fill the water heater up and the colder water heats up causing it to expand. This will increase the pressure in the pipes. *) In my case ~150PSI. (The pressure release valve on the water heater is usually not working.) (same brand at HD !). A pressure gauge with a red witness pointer will confirm this. 4. I resorted to installing an electric pressure switch which operates a cheap sprinkler valve to release excess pressure through a 1mm hole. (After a shower, about half a pint.) Keeps my water heater from bursting.

[@amvetprohomeinspections6627]

Agree. I'd also like to add that the potable water distribution piping in the video appears to be copper going to polybutylene. Polybutylene (PB) piping has a history of weakness/decay/ruptures over time. So much so, that some insurers won't cover a home that has it. My point: Adam - Careful. I'd error on the side of keeping the water pressure low in PB and avoid regular manual adjustments/fluctuations in PSI. Excellent video you made.

You really need a gauge with two needles one tells you what the pressure surges to at night. That is the most important thing, If you have a regulator it creates a closed system. so you need to relieve the pressure with an expansion tank above your hot water tank. This comes from more experiance than this guy is old. I used to be a A plumber that solved problems. This is one of the most common ones.

Great video, Adam! I appreciate how you use a tripod and get some good, clear closeups. Audio is good, too, though it started off a little low - but I have seen so much worse! I have some questions that perhaps you or other readers might be able to help me with, if possible. I am trying to find my pressure regulator, but what I see doesn't look like any other pictures of regulators. My home is just over 60 years old in a suburb of Salt Lake City. The main line comes into the house in the basement. There is the old dial-type of shut-off valve about 6" up the pipe after it enters the house. That shut-off valve is part of a slightly fatter joint (for lack of better word) that is about 2" and on that fatter part is a screw-knob. My guess is that that joint is the regulator and the screw adjusts it. Does anyone know if that is the regulator? Another foot or two up, is the lever to shut the water off to my house. I think that may have been added later since it is more modern. My next question is my fear of increasing pressure in an old house like that. The upstairs main floor is pretty bad, and the basement isn't much better. We had the basement finished (putting in a bathroom), and since then, there is knocking when the washer water goes on and off. I'm concerned that even if the water pressure is low, that raising it a fraction will hurt the pipes especially with the on/off knocking of the washing machine. btw, I have called the city and they will send someone out to check the pressure at my meter. After that, I might also buy the gauge to see what it is inside my house and if it varies much from their gauge. But any ideas about my regulator and the knocking would be greatly appreciated.

You don’t have a pressure regulator/pressure reducing valve. They don’t usually install one unless needed if pressure is greater than 80 psi. Normal pressure should be between 40 and 80 psi. When pressures are greater than 80 psi. The sound you’re hearing since the clothes washer was installed is called water hammer. This requires installing water hammer arrester on both the hot and cold supply for the washer

@@MsGreenInspector That is great to know about the "water hammer" - thanks! I did have the city come out and the pressure was normal. Since writing my original comment, I have had the main water line replaced (it was the original 60-yo galvanized line and looked like Swiss cheese with all the holes in it!) and had a plumber replace some of the inside pipes (from the main to the hot water). I've also added a water softener to the hot water line. While there, he cleaned out or replaced some of the faucet and toilet lines, and the flow is so much better! Old pipes and hard water - ugh! Little by little we'll get there.

Thanks so much. We would get a drop in pressure if the dish washer was running. Did 1 full turn and we have perfect pressure regardless now

[@jr6879]

What if you want to increase pressure in a closed system with an expansion tank? Is it the same, just turning the screw on prv? Or does the expansion tank need adjusted too?

[@LyndaHeines]

Informative. However, I don't have a water pressure valve. Humm.. Any suggestions on what I can do to increase our water pressure. If I do laundry OR water the garden, there is very little water pressure in the house.

[@annescofield8461]

Lynda Heines same here!

[@Alimaom]

if the city send water at 60psi would that valve give your home 75psi?

I’m also in a new house(year old) when my sprinklers comes on in the middle of the night my pipes rattles for about two secs until the it is pressurized, but when I turn on a faucet then turn on the sprinklers it won’t do it. What gives? Thanks and great video.

[@wamu8851]

Just...excellent video. You saved my day!!!

[@GospelMusicians]

Hmmm I live in FL and don’t have anything like this.

All houses have a main supply line to the house. I looked everywhere in my gf's house a few months ago and couldn't. I finally found it last night when I realized a weird bench like box in the basement in the corner that's covered with boxes and stuff. It's not screed in or anything. I moved it and voila. Usually it's by the front of the house. It can be in the garage, basement, closet under stairs (don't know if that's a legal place, but worth a shot to check), and sometimes outside. If you're looking outside, be sure it's a waterline and NOT GAS. There should be a label or color coded. I believe yellow and/or orange is gas. I'm not sure. I think the attic is another place it can. If you love in a condo it might be harder to find. Just because things like water lines have codes to be followed doesn't mean that the current or previous owners hired someone that goes by the code or they did it themselves and don't know the codes or didn't care.

Will Reducing water pressure helps me get rid of my pipe noise inside the wall? sound like a banging on the wall.

[@soozspenser]

I hope it's not ghosts. Lol. But ghosts are actually real. If it's a plumbing problem you can fix it or get a plumber. If it's a ghost problem get your house smudged. You may Google what ghost smudging is all about.

[@Skiwatch11]

Thank you so much! I finally have water pressure!

My regulator appears to be in a water meter box in the carport. When I opened to check, it was covered in dirt all the way to the top of the meter box space. I've dug to find it under the dirt. Someone in my condo (50yrs old) had a flood inside because the regulator was "corroded" and it blew out the water heater inside. Now everyone including me is wondering if we should all replace our valves. What do you think? Thx.
