How to Fix Kitchen Faucet with Low Hot Water Pressure 

This video saved my sanity. After tearing apart a wall to replace a supply line that had been clogged, I put everything back together only to find the hot side still had low pressure. I was ready to tear it all back out, but googled the problem first. I was able to clear the debris from the mixing valve in seconds. You, sir, are my hero.

My plumber quoted me $1000 to replace the entire galvanized pipe to my kitchen faucet- said it most likely was a build up in my pipes. How wrong was he! Your tip fixed the slow flow for free! Thank you!

Incredible. We had been living with low hot water pressure for about a year. Stumbled upon this video, took 5 minutes, and it’s completely fixed. Thanks for posting!

It worked!!! I had tried about 6 different (and time consuming) trouble shooting suggestions that did not work. This took about 2 minutes and I have water pressure again! Thanks so much for posting!

Spent 3 hours trying to figure out why my hot water wasn’t working. Found this video at the very end. THANK YOU!

Can't understand why a new faucet would have so much gunk in it. Terrible workmanship if you ask me. Just installed a new faucet and having the same problem. I'm going to give this a try. Thanks sir for posting a solution.

Yes! Did the trick for me. A finer point on the sequence, at least, this is what I found. Start with the valve open on the hot side, rotate to cold (keeping valve open), run for 5 secs (or more), switch back to hot (again, staying open). Leave it on the hot side and allow the water to release out of the hot line. 5-10 seconds. When it slows to barely a drip, repeat the sequence. As you repeat the sequence, you'll see less and less water backing out of the line. When I got no more backflow, I re-connected. I did the whole thing three times, with debris coming out each time. I could've kept going, but I'm inpatient, and it came back to 95% of the cold water side, which was good enough for me. Thanks!

This solution fixed my problem in under 10 minutes. That's especially impressive since the plumber said we'd need to replace the entire faucet! thanks man!

You deserve an Academy Award for “Best Useful Advice of the DECADE”! I have 5 bathroom Delta faucets, 2 kitchen Delta faucets and 1 laundry room Delta faucet. One of the faucets had very LOW HOT WATER FLOW RATE. I tried your extremely simple advice and now the hot water flow rate is exactly as good as the cold water flow rate. THANK YOU SO MUCH!

Thanks so much for this advice. Went on a trip in June and was gone for a month. Came back and hot water pressure was severely reduced. I procrastinated for several months and finally on New Years day started looking for some DIY videos and found this one. Easy fix, probably took longer to clear out the clutter under the sink than it did to fix the issue. Thanks again.

Thank you so much for posting this video!! I did just what you did and was amazed at the sediment , rusty metal flakes and crap that was making my hot side of the faucet barely produce a trickle. You saved me a plumber call and it was great to be able to fix it myself! You are sooo the man! My hot side now has very nice flow like it did when it was brand new. Woohoo!!

Husband was ready to spend big bucks to replace faucet until I saw this video. He said there was no way this would work and he had done everything else …but I insisted and what could it hurt……. My husband for the first time ever said he should have listened to me the first time THANK YOU! Hot water now with pressure in my sink!

After procrastunating for 2 weeks, i finally tried this today. Worked perfectly!! And simple too! Thanks for posting 😊

Thank you! When troubleshooting anything I always think it's the worst thing possible. This took 30 seconds and made the wife very happy.

Oh thank you thank you!! This video was my second find in RU-vid to try and help my sadness of my new faucet not working properly and we tried it and mystery solved and happiness restored!! THANK YOU 😊

You are a lifesaver man. This has been killing me for weeks. Runs like new now!

Thank you for this great tutorial. You saved me time, a plumber visit, and a little sanity.

I second what Karl Lichtenstein said. You saved us time, money & our sanity. Thank you for sharing this informative video!

I've been dealing with this for over a year, and finally did this, fixed the problem in 15 minutes. Thanks for posting.

You, are a Golden God! I replaced a 3/8” tee, a globe angle valve and no luck. I was ready to go buy a new faucet then saw your video. I thought, “no way”! You ROCK! 👍🏻

OMG… This worked. And my wife let me sit around on the couch for the rest of the Saturday after my triumph. Thank You Bro!!!

THANK YOU. I installed a new sink today and everything went smoothly, until it didn’t. This solved the problem. You saved me from having to call a plumber.

Thanks for this video! Such an easy fix after a frustrating time trying to figure this problem out. My handy father and I (not handy) tried everything but this. I wouldn’t have thought this would’ve been an issue as I just installed a newish faucet and lines within the last two years, but low and behold, you were right!! Again thanks

This video has saved us *two* sinks (and a lot of $$$ and headaches)! We fixed our bathroom sink a few months ago, then when my father-in-law had new kitchen counters installed and the hot line on the kitchen sink only put out a trickle, we knew exactly what to do. Thank you!!

Ha. After waiting for months I found your video and fixed it myself. Saved a lot of money. Thank you for you easy fix video.

Haven't repaired mine yet, but based on the comments, it's safe to say that my problem will be resolved as soon as I follow your money saving instructions. Thank you.

I replaced the leaking shut off valve thinking that would solve the low pressure issue as well. I saw your video and gave it a try. Much black coal debris was flushed using this method and pressure back to normal. Thank you!

THANK YOU SO MUCH!!! I was getting so frustrated. I just installed a new kitchen faucet today. I had to pull it all back apart and make sure there were no blockages. I checked the supply lines too. Then I was told there might be a blockage from my water heater to my sink. My water heater is in my attic. I was not happy to hear I might have to crawl up there and possibly go into a wall looking for a clogged pipe. ALL other faucets were working perfectly. Then I jumped on here desperate and found your video. It took less than 5 minutes and ALL this black rubber looking rocks/gunk came out. It's working perfectly now. You rock!!!

This happened to me right after I replaced our kitchen sink faucet cartridge so I thought I had done something wrong in that process. But I found your video and I am so happy because it fixed the problem and now I have hot water and a non leaking faucet. I’m so grateful! Thank you!

This worked for my wife and I after installing a Delta faucet. Worked fine for about a week then the exact issues happened to us. Thank you for this video and God bless!

Great video and saved me a ton of troubleshooting! Took me two attempts to get back to full. First time the pressure was only back to 30% or so, but I knew it was working. Did it for longer the 2nd time and back to 100%. Thanks!

Worked like magic! I thought I'd have to get a plumber to clear my lines. Surprisingly, no debris that I could see was captured, but the pressure was restored to normal. Your quick and simple video saved us money and I learned a new fix for the future. Thanks for taking the time to educate the masses!

That did the trick! After two years of low hot water pressure it is now fixed. Thank you!

After thinking my new faucets internals melted, and a trip to home depot for a replacement and having the same issue. I can say this video helped me fix the issue instead of getting another replacement!

What a life saver this video is... I have a two handle faucet set up so the back flush procedure was slightly different, but the results were just as successful...

Like other comments here I had almost NO hot water pressure and no matter what I did, I couldn't figure out WHY it was only a trickle. I stumbled upon this video while searching for a solution, tried it and saw all the stuff that was clogging the hot water line spill out into the bucket! Once I reconnected the line I had FULL PRESSURE HOT WATER! Many thanks for making my day!!!

Worked for me. Thank you! I would have been chasing down all other bad solutions. Never thought of a problem in the mixer and wouldn’t have known how to get at it.

Thank you for the video. Just had a new hot water heater installed. Water in the kitchen was running slow because of the old debris. This fixed the issue in 10 minutes. Bravo!

Thank you for this great tip on restoring water pressure on faucets. It was very simple and easy to do and now my faucet works great.

Thank you! I used the technique in your video, and fixed the hot water pressure in my kitchen faucet! Saved me an expensive plumber bill!

Thank you!! We moved into our 1940 home 1 year ago and our hot water in the kitchen sink has only ever been a trickle. We fixed it thanks to your advice!

This totally helped! I had already run water through the line so I knew it wasn't clogged. I unhooked the hot water line and did this flush. I found out that the o-ring had turned sideways. I reseated it and was good to go! Thanks for the video and the recommendation!

This was a life changer. I had talked to several ‘plumbers’ and the gas all kind of ideas. This has been a problem for over a year. Followed the steps and it “WORKED!!!” Now have the hot water pressure I expected. It took me longer to remove all the stuff under the sink then it did to fix the issue. 😁. Thank you so much.

My hot water flow was a little more than a trickle. This video saved me a lot of work and money, the technique worked the first time. my wife and I thank you Sir. This man should have a patrion account to be compensated by the diy’ers he’s saved time money and aggravation.

Bro! Dude! This method totally works. I took my kitchen faucet apart and this whole time the solution was so easy! Thank you for this knowledge sir!!! Have a blessed day!!!

Thank you! Thank you! Thank you! Worked perfectly to flush out a "rock" about the size of 1/2 pea. It appeared to have metal filings with calcium all around it. I backflushed it right into the little bucket. Now everything works fine. PfisterCompany said to buy another cartridge, which we did, that didn't work at all to solve the problem. Pfister should have a direct link to your video. BTW, I am a 74 year old female and did the work all by myself with the help of your video. Thank you again.

I doubted this was the cause of my almost complete lack of hot water flow on my kitchen faucet. However I did exactly what was demonstrated here and full water flow was restored. Thanks so much!!!

Thank you man!! As the comment below you saved my sanity!! I knew debris was the problem and couldn’t disassemble the faucet to get out.. cheers!!!

Thank you! You are spot on! This fixed my problem. After I installed my new dishwasher the hot water flow stopped. I went on You Tube for some help but found non until I came across your video. This was a simple fix. Listening to all the others sounded really complicated.

Thanks so much for such a direct and simple video. I just bought a brand new faucet from costco 3 weeks ago. My husband just went to do the dishes and boom, hot water pressure gone. He had a fit I bought a crappy costco faucet and stressing out how life sucks lol (it's a moen) I googled how to fix hot water pressure in kitchen and your video was the first to come up. It wasnt the faucet. He flushed it and a bunch of black stuff came out like yours. You fixed the problem and saved us from having a fight lol thank you!!

I literally just had the utility company come out because I thought the problem was my hot water tank. The tech explained to me that it was my piping and the whole house needed the galvanized pipes replaced. 3 minutes into this video I have full pressure in my kitchen sink and shower 🚿. Thank you!

This worked like a charm on my Pfister kitchen one handle faucet. After 8 years or so, the cold water pressure was fine but the hot water was down to almost a trickle. I was about to buy a new kitchen faucet. I tried this 3 times and after each time I would hook up the hot water line and turn on the valve. Each time I redid this I got a little more sediment and now the hot and cold are the same pressure. Thanks!!!

Wow! Thank you for helping me get to the bottom of my issue. I was beyond frustrated after hooking up my dishwasher and then not getting hot water to my faucet. Didn't make sense but it worked like a charm. I flushed a ton of particles out. Works great now!

Thank you!! This fixed my problem, after I had to replace the hot water heater. A few small specks of rusted metal for flushed out, and it then worked perfectly.

Thank you for this video. I ficed my faucet today. I almist bought new faucet when I decided to search on you tube. Thanks again.

Thank you. It worked great for a few seconds then both hot and cold had decreased water pressure. Turns out that some crud had gotten to the cartridge in our Moen faucet. My husband took out the cartridge and let water pour into a pitcher and more crud came out. He also disconnected the aerator and cleaned that as well. Thank you so much. Saved us a plumbers appointment.

This worked for me. Elegantly simple. Thanks!

Holy crap man you’re my savior! My hot water was a trickle for over a YEAR. I did this and BAM! Hot water working again! It’s just as strong as the cold water now! Thanks! Who knew a few little particles could effect the pressure so much!

Thank you! Thank you! Thank you! You helped to relieve some stress after a storm! Brand new faucet is up and running!

One of the simplest solutions to a problem that I feared was much larger and much more expensive to solve. Thank you for sharing.

Thank you!!! Problem solved after 5 months of trickling hot water in the kitchen. I was just about to call a plumber, luckily I found you on RU-vid U.

Thank you so much for sharing your video....I was going to call a plumber or a handyman...But they took to long to get back with me. Talk to my son and he suggested going to you tube , and we found your post...I don't mind paying for service(s), but when people take to long to get back with me, ugh! Thanks again!

Great video! I used this today at my job. I’m new to maintenance

Thank you! This took me less than 5 minutes and fixed my kitchen sink. I was worried it was a supply line from the water heater or something worse.

Thank you so much!! After months of trying to figure out what was causing low hot water pressure. Your you tube video fixed it in less than 10 minutes. Thank you again!!

Thanks for putting this video up. I tried it and it saved me a bunch of money.

After going through the routine as explained it worked like a charm,( 5 minutes.) thanks your the man

Life saver. Worked a treat on ikea tap that suddenly lost hot pressure.

Thank you!! I was afraid I was going to have to replace my faucet, $$. All this cost me was about 10 minutes of my time. It worked perfectly.

Thank god i found your video. I been recking my brain on trying to figure out what the problem was and lord and behold your technique worked.

Thanks. You just saved me a call to the plumber.

I've had bad pressure for a couple years and was tired if it, this fixed the issue in just a few minutes

Thank you very much. My granddaughter and I had just installed our new faucet but puzzled by trickle of hot water. Your fix was amazing. Lots of black plastic in line.

Thank you! Your method worked just like your video showed. The gunk that came out looked very similar to yours. What a relief!

I put up with a low pressure sink for two years. Fixed it in 10 minutes thanks to your video.

This is the only video you need to watch. I noticed our hot water pressure in the sink was low. I turned the valve to increase the pressure and the pressure got worse. Now, I have no hot water. I tried to get a hold of a few plumbers but because of the Christmas holiday they were days out. My wife was going to cancel Christmas breakfast if I couldn't fix the sink. I told her we can still wash with cold water and besides we have a dishwasher. She refused... Within minutes of watching this video I now have full blast hot water. Thank you

I was pulling my hair out (what's left) trying to figure out to fix this very issue. I was about ready to toss my faucet and get a new one when I came across this video. Thanks for making it, and in particular keeping it brief and to the point. Well done!

This was exactly what was wrong with my hot water supply. Very helpful

Incredible!!! You just saved my wallet sir! Thank you very much!!!

Worked like a charm. Thanks

This worked for my kitchen sink faucet! I actually set the handle to the mid point instead of alternating between hot and cold. This way cold water was just constantly flowing out of the hot water line until unclogged. I had to remove the spray head and clear that out as well.

thank you so much for this video! solved my problem for me right away, you're a legend!!!!

I will give this a try! Thanks so much for posting this.

Thank you so much for this video!!! My apartment's kitchen sink always had low hot water pressure and then tonight it had none. This video saved my life!

Just solved my annoying problem with low hot water pressure in a brand new faucet following this video. Thank you!

Okay. I never leave a comment, but I just had to. I hooked up my new dishwasher that finally came in yesterday. All the sudden, my faucet didn’t work right. I was wicked irritated that one problem fixed caused yet another. I googled, saw this, tried it, and it worked immediately. Took a min. Thank you for saving me from being in a bad mood, which would tick off my house, and a downward burnout spiral of pointless projection arguments that follow.

thanks guys! this was a way better video,, crucial to alternate between cold and hot,, that cleared out the line for me finally!!! ❤❤❤🎉🎉🎉

I thought I was going to have to tear out a wall to fix mix slow hot water in the bathroom. This video saved my bacon. Tip: just turn the water faucet on between hot and cold and the water runs right to the hot water side from the cold side. I had to do this about 4 times, connecting and disconnecting the hot water line each time to flush in both directions before my valve finally cleared.

Worked like a charm

Thank you!!!!!!!!!!!!!!! You saved my sanity!!!!!!

Thanks! did the trick. I also ran the dishwasher to help flush the line.

We followed your instructions and it worked!! 😊 Thank you!!

I definitely appreciate this video!!!! Was able to save my parents some money because they were about to call a plumber! Did exactly what you said in the video and it worked perfectly!!!!

Worked like a champ. Saved me aggravation and money. Thanks

I tried other methods until I seen your video. This helped my problem with the hot water. Thanks for sharing

Great video and perfect solution.. saved me so much time and likely unnecessary work! Thank you!

Thank you thank you thank you. This worked and as someone else said, it took longer to clean out the cabinet than it did to fix the pressure issue.

Thanks that worked like a charm. The gunk that came out was part of a rubber washer. Not sure were it came from but nothing is leaking so I think we are good. Thanks again.

Great video!!! Worked like a charm, and I’m sure saved myself a lot time and money!!! Thanks again!!!

Absolutely worked! Thankyou!
