Easy Fix For A Kohler Running Toilet That 'Runs'

We show how to quickly repair or replace the gasket used in a modern Kohler toilet tank system, which does not have a traditional 'flapper'. You can fix your running toilet yourself with no experience in 2 minutes.

I am an 80 yr old Nana all set to call a plumber also. The video was so well explained. I went to Home Depot purchased a gasket for under $8. There is actually a packet labeled for Koehler. I couldn’t twist it from the top and was afraid I’d snap the tower. I lifted the cylinder and twisted it off near the bottom. Put the new gasket on. I was so pleased with myself.

[@VioletPixii]

I'm so proud of you 🙂 this video helped me too

[@judithhileman-lj4lj]

Good for you! I’m 69 and have to go buy a gasket tomorrow! Sure nice to learn to save some money!

[@kaeellenpearson5158]

Thank You! An 81 year old lady fixed her toilet with an unattached seal! Saved me over $80! Love you!

[@carolewilson288]

I am a 72 yr old granny who was all set to spend $150 to have a Plumber come and stop my toilet from running. This video took all the mystery out of fixing the problem and it was the first time I ever tried to fix something by watching an online video. My friend and I spent about 10 minutes pulling the cylinder out and cleaning off the gasket. Girl power at work...THANKS for making this so easy to understand.

[@URTechDotCa]

Hi Carole. Thanks for the kind words. I am glad it helped.

[@coredumperror]

I'm a 36-year-old single guy who also used this video to fix my own toilet. I love how the internet is an equalizing force for all!

[@loulouncmtn]

That’s exactly why I am here! Thank you

[@davidandpamwilliams3885]

Same here...I was determined not to pay someone $150. Toilet fixed...thank you so much!!

[@brynn.grumstrup]

In addition to the helpfulness of the instructions, I enjoyed how adorably Canadian he is at 5:02 "We hope you enjoyed this - well, enjoyed is probably a bit strong..." 😂😍

[@gkzn123]

When I first saw this toilet at my daughters house I was overwhelmed to work on it. After watching your video and fixing her slow leak I’m still her amazing dad. Thanks again.

[@BTCKYLE]

😂

[@glenrespicio4063]

I just cleaned my Kohler gasket as you said , now it’s not dripping into the bowl. It had deposits on the gasket and black deposits in tank . Cleaned it and it’s running like new . Btw , it’s 10 years old . Thanks for the video. Aloha , from Honolulu ,Hawaii.

[@suz567]

Thanks, I’m a 77 year old woman living alone. Did it! Thanks to you and to KZbin!

[@URTechDotCa]

I am glad it helped. Thanks for the comment Suz!

[@seobryancornett]

Glad I have a Kohler. I watched this video, ordered the part from Amazon, and fixed it in about 5 minutes!!!! Thanks to these videos, you can do most everything by yourself, and I'm 78.

[@groovygwen]

I have been searching for how to fix my toilet for months. I accidently stumbled across this and boy, I am so glad. I already paid a plumber friend last year to fix it to no avail. Now I can do it myself and know it's fixed. By the way, I am a 71-year-old woman living on a fixed income. These things are important to me. I also loved that you dispelled the notion that all the gunky stuff was nothing to be bothered with. You made me believe I could fix it. One of best videos I've watched. Thank you, thank you, thank you.

[@1954evelyn]

Thank you for this video, I bet I watched over 20+ videos and yours is the one that helped me fix my toilet!!! I have this same toilet and I did not know all that info is inside the lid. I was able to order my flush handle from Amazon as well with the part number from the lid. THANK YOU from this 67 yo woman!!

[@URTechDotCa]

Glad it helped!

[@1954evelyn]

@@URTechDotCa Thank you got my handle yesterday from Amazon NOW I don't have to remind people to raise the handle when flushing. After I forgot to tell a visitor to push the handle down last week the toilet ran for 24 hours before I found it running. Not sure what our water bill will be from that I am sure not as much as a new handle and rubber gasket. Thanks again for making this video you saved me.

[@dannydahlke1845]

This was one of the most useful videos I've ever watched in my life. Thanks for creating and uploading!

[@thepianofuzz]

I totally agree!

[@EagleQ]

Indeed, a lifesaver as well👍

[@URTechDotCa]

Thanks!

[@bradtisch7803]

I must be a light sleeper because my leaking toilet tank was keeping me up all night. Who knew the solution was so simple? Thanks a million for the video. I’ll have the ring replace first thing in the morning!

[@brynn.grumstrup]

Same! It was totally wrecking my peaceful slumber.

[@user-sk5oy8wu9u]

I watched your video and fixed the toilet while my husband was at work. Thanks!

[@spirit043]

I was all set to go out and get a gasket but tried your suggestion of rubbing the gasket to get off any water calcification and it worked! Thank you so much. Best tip ever!

[@ginamainprize4874]

Thank you! 34 year old first time homeowner replaced it within minutes, I can cancel my handyman appointment now!

[@pamelahowe4746]

I had a friend replace the gasket and thought the problem was solved. Unfortunately it still was running. The next day I watched your video and realized that he did not attach the gasket correctly. I followed your directions and fixed it in 2 minutes. Thanks

[@jillpotter1]

Thanks so much for sharing this! It's our first night staying in our relative's apartment in NYC, and the toilet wouldn't stop running! I was sure I'd be up all night. After watching your video, I realized that the pink gasket had folded, and that was the reason for the leak. How nice to hear silence, and I'm looking forward to an undisturbed rest!

[@michaelgarzapopeyessnocone4469]

This is the best video & explanation as well as the repair on my running toilet! I don’t comment, but I can’t resist expressing such an easy repair. My situation , was actually the red rubber seal, apparently it came out of the gruve. I had already purchase a fill valve and flapper cuz I had the day off and didn’t want to be running back n forth to lowes. After seeing this awesome video , I didn’t even have to use what I purchased!!! I made the decision that it wasn’t totally decade or fragile. I just set it back in the groove and whola!!! Hahahaha. 👍

[@camillehaffner7162]

Thanks for this! I looked inside and was unfamiliar with this kind of toilet innards until I watched this video. I checked the gasket and it wasn't even in place! No wonder it was running! Thanks again!

[@PhotographyByLenny]

Thank you so much. I know how to replace a traditional flapper, but I didn't know what to do with this thing. You saved me a plummer bill. Keep up the good work.

[@irinadruskin1233]

Thanks a lot to you and Internet, I could fix it. My problem wasn't even in gasket itself, it simply fell out and I didn't know how to put it back on to its place and where the correct place for it. Now, even if the gasket isn't good, I know what to order and how to replace it. THANK YOU!

[@nene1066]

A plumber quoted me $350 without even seeing the issue all I described was the hissing noise. I tackled it myself with your video on hand. I feel very empowered as a result. Thank you sooo much Hid bless you for your service to your community.

[@URTechDotCa]

You can do it! Good to hear this helped. Thanks for the kind words

[@AnnEvelyn7]

This was EXTREMELY useful. I watched another video and was convinced that I needed to replace the entire flush system. But, after watching your video, I opened that canister and discovered that the o-ring had deteriorated. So, I just ordered one from Home Depot. Will pick it up later and replace it. The complete system was only $20 so I will keep it on hand, but I really only needed that $8 rubber ring. Thank you!

[@jeanleonard3440]

Thank you for your clear instructions. I ordered the part from Home Depot and fixed it in no time. I've never done anything like this before. The toilet does not run anymore!

[@katk1035]

Thank you! Your demonstration on how to take the unit apart helped me to fix mine. It is not the gasket, but clogged inlets; but I cleaned it up and it now works. Bravo!

[@URTechDotCa]

I'm glad you got it to work :)

[@johnhinnen3128]

I had this issue and waited for two weeks for a plumber to show up. Finally did this morning and told me I needed a new toilet to the tune of 1600 dollars. I told him to take a hike. I watched your video and fixed it in two minutes. Thank you, thank you, thank you

[@URTechDotCa]

Great job! Too many scammers and sooooo easy to fix yourself.

[@tyewebb4543]

Wow. I was about to pay $75 to for a service request to my home warranty company and saw this video and fixed it in less than a minute. Thank you

[@TB-on9nb]

Simple fix. My wife wanted a new toilet. Noise was driving her crazy. Ty saved me some money.

[@sally5846]

I couldn't figure out how to fix my toilet. Thank you!!! You've lowered my blood pressure.

[@URTechDotCa]

Hi Sally; It is simple problem no-one should spend any real money on. Stay Safe!

[@aafife499]

Thanks for posting! I went in to do the cleaning of the gasket you recommended and found it had just popped off. Put it back on and all fixed!

[@kieranoconnor6724]

thanks for saving me a trip to the store! I have two of these toilets, but have never dealt with that gasket. Didn't quite realize how it worked. Now I do!

[@morganbarnes7286]

Excellent video! I don’t know crap about crappers and I was able to fix my toilet for the cost of an O ring. Brilliant!! Thanks!!!!!

[@misteress8008]

Wow! great video. Exactly the problem we're having, had no idea it was that easy. Used to seeing old school guts in the tank, so this video was well done, looks super easy. Almost went out to replace the entire toilet.

[@thatothergirl3135]

This video was the best on a running Kohler toilet.... times a million.

[@SirHeadly84]

This video is great. I have NEVER worked on this toilet by myself other than adjusting the chain. It was just as easy as you showed here. I was also able to set the water level properly while I was in there because the instructions are pretty good as well! I did this all at 1230 in the morning with zero tools just like you. Extremely simple and I would recommend ANYONE try this BEFORE repalcing anything, calling a plumber, or buying a different toilet. Thank you for making this video!

[@bobjeffrey8863]

THANK YOU.. Your videos are SOooo EASY to understand

[@ajw5743]

I searched this video after installing a brand new kholer that was running. The video did not solve my problem, but as a result of inspecting the mechanical parts I found the solution for my situation. The chain which connects the arm to the float was installed too tight out of the factory. I had to unclip the chain and install it on the next loosest link. Now the toilet works and is no longer running continuously

[@babyjesus454]

You fucking rock dude

[@miker48]

Scraping the o-ring with my finger worked perfectly--thanks!!

[@CKelly12969]

Thank you so much…you saved me a bunch of money. My 3 month water bill is usually under 300….last bill was 900….next bill should be back to 300. Thanks again,

[@johncolvin2234]

Thank you!!!!! Knowing how that top piece comes off saved me all sorts of time.

[@user-ni4rr5tn6x]

Great instructions! After our plumber put the new gasket on, the toilet still ran. So I followed all your instructions myself, and it still ran! But then I noticed my water was not filling up to the water line... I turned the screw clockwise about 30 times to get the water level up and that did it! It made sense then, as it's a sort of vacuum - AquaPiston.

[@Land-Shark]

Thanks for this video! :) My Kohler started running recently. I'm glad I won't need to replace the whole flush valve assembly. The gasket on mine had developed a small gas bubble about the size of a cooked grain of rice, and had no mineral deposits, so I popped the bubble and will see how it goes until I can get a new gasket. This video made it super easy. Thanks :)

[@TSKseattle]

I had a hardware store counter guy warn me to NOT twist the disc at the top, but to reach down under and twist the base. He says he has several people a month come in with the disc broken off. I did this seal replacement to day and took his advice, worked fine. In this video your hear the *creak* as he twists it, that's the bound up base that can cause it to break. The seal was a 2-pak for $10

[@victoriasnodog161]

Thank you!!!!! Just rubbed off the calcium and all is good. Today you're my hero.

[@omgwhytho1543]

Thank you so much for this! Cleaned the calcium off and it is finally working again.

[@treetoptreetop2730]

Just what I needed. Thank you for sharing. This video was very helpful

[@Americanliberalelite]

I was going to call a plumber, but decided to give it a shot myself. Thanks to your video I got this job done in less time than it took to refill the tank.

[@Forgivenformymistakes]

Thank you. No other video was similar to my toilet and so your fix helped get my toilet from running sporadically for a few seconds to refill.

[@fancypearls1896]

Thanks, I just got that running toilet of mine fixed. Great video.

[@kassimmohammed2567]

I fix my toilet in less than a minute after i watched this video. Thank you.

[@mikeolgren7359]

Dude. You just saved me $200 and a long wait for a plumber (they are booked out weeks around here). Just like you say it took me 2 minutes to do this fix. Twisting to remove the cylinder took some force, but otherwise smooth sailing. Only needed to clean the flat rubber ring, so literally no money spent. I am forever grateful.

[@URTechDotCa]

Glad I could help

[@paulmurr1351]

Worked exactly as described (except for driving to the hardware store). It literally took about two minutes to get the old ring off and another two to put the new one on. :)

[@weenerdoggs]

I did enjoy this video! Your good quality info and sense of humor are most appealing!

[@talongodin2253]

Thanks so much for making this! You have a way for simplifying tasks into layman's terms.

[@URTechDotCa]

Glad it helped!

[@tiff5747]

Thank you, I was able to watch this and fix the toilet myself.

[@robertsoreda7227]

Thank you so much for your videos!!!!! Was about to take apart and replace that unit!! but after watching your videos.. I just did what you said, and cleaned everything,, and now no more leaks!!! Thanks again!!!

[@URTechDotCa]

Glad I could help

[@francesm4113]

Thank you so much. I just fixed my toilet with your excellent video.

[@Leafland99]

Thanks for this, you just cleared up the rest of my day based on this video. Five minutes tops for the repair, and that included the fill when I finished.

[@URTechDotCa]

Glad it helped!

[@xixcheliexix]

You are the best!!!! Thank you for this, it was so simple to follow and easy to do!!!

[@HardmanKnott]

Thanks much for this video. My seal somehow became dislodged, and so I simply flipped it over and reinserted into the groove. The rubber was still plyable and so decided to reuse it and save a trip to the hardware store. I had no idea how to remove the parts until I saw this video.

[@URTechDotCa]

Glad it helped!

[@stephenwilliams6892]

Thank you! I work at a hotel doing maintenance and this helped me solve an issue I couldn’t figure out

[@brr5459]

Thanks for suggesting to try wiping it off. That's all I had to do! No trip to the store and no repair needed. Thanks!

[@jimj5617]

Great clear to the point video!!!!!! I think yours is the best!

[@Holdfast1812]

Thanks so much for this. As an official "old guy" I had no idea where to stop the running from on these toilets.

[@robertbylo9614]

Thanks for the simple solution. Very helpful

I'm glad it helped :) Thanks

Worked like a charm and saved us lots of money, thank you!

[@tomlawlor7144]

Great video , many thanks. Simple to understand, I fixed the running toilet is less than five minutes. !!

[@adamsamad]

You're the hero we need. Thanks. Just cleaned my washer and the plastic piece with toothbrush and light soap. And it worked.

[@URTechDotCa]

Glad it helped. Thanks for the comment and sorry for the looooong time lag on the response; I have been in Hell in recent months with... lots of personal stuff. Thanks again.

[@chriscutress1702]

This was handy to learn what wasn't my problem. I traced my problem to the "flush or trap handle" after exploring the problem suggested by this video. Kohler has a mechanism that fits into a square hole on the outside of the toilet. The actual chrome handle has to be able to move through this mechanism in order to full and release the chain. After time the plastic mechanism can expand and tighten down on the small metallic pipe that actually goes from the handle to the metal (or plastic) rod that attaches to the flush chain. My fix was to gently drill out the plastic locking section of the "flush handle mechanism" so that the metal rod was no longer hanging up when used. This allowed the mechanism to work properly and no longer hang up when flushing the toilet. No more annoying running toilet. I haven't seen this mentioned on any other Kohler repair video so thought I'd post it here in case anyone want to update their presentations.

[@smartphonerepairwi775]

Glad I stumbled on your video. This is exactly what my toilet is doing. I'll definitely buy these. Thanks! "EDIT" I bought a 2pk of yellow replaceable seals from Amazon and it worked as new. Thanks again!

[@curtvogue5720]

THANK YOU! We have the exact same problem... all the videos I've seen have said I have to take apart the back of the toilet, this is so easy in your video. 👍👍👍👍👍

[@URTechDotCa]

Glad it helped

Super helpful to help diagnose and resolve. Thanks for help :)

[@suntemple3121]

Thank you for this information, and demonstration all the Best.

[@bwright7063]

Five stars***** Thanks so much for being so very helpful and getting strait to the point! It really was not that hard at all! Scraping the calcium off till I can get to the store and have the gasket on hand when it really fails is genius money saver too! Some of the videos just run on and on and take an hour for five min of advice and I have to skip though all the babble to get to the part I really need. I know it's free advice but it just made me a little bit happier so had so say thanks again.

[@4bu41i]

Amazing! I was about to make a real mess of things before seeing this. Thanks!

[@miker48]

This video has saved me from having to call a plumber twice. Thanks so much!

[@NekBodesh]

Wow thanks so much for the video. My water bill this quarter was in the triple digits when it usually is about $50. Checked my basement toilet and noticed that it was constantly running. The O ring developed 2 blisters, preventing the flush valve from sealing. Thought maybe it was dirty but now I just need a new O ring.

[@jordanpolite2808]

Omg this actaully worked! Thank you so much man, keep the great videos coming!

[@URTechDotCa]

Glad I could help

[@winterwendigo2431]

Thank you so much! Turns out the ring on mine had just popped right off, super easy fix! :D

[@URTechDotCa]

Wow. I have never seen that before so thanks for the comment. Either way it is an easy fix like you said.

[@jilliansaturn8946]

Thank you so much for this. Fixed an issue I created installing a bidet. When I tightened the nut at the base of the tank, I accidentally turned the floater thing, causing it to jam up against the side. I wouldn't have been able to figure out the nonstop running if not for this video. After inspecting it, I realized I just needed to turn it back into place and the problem was solved! I feel like a dope having done that, but super pumped I didn't have to call a plumber!!!

[@URTechDotCa]

Glad it helped. It is an easy fix, but many people are too scared to try it. Good for you Jullian!

[@johnhassan9003]

Just saved me the price of the whole toilet kit.... thanks!!!

[@NW2020]

Thank you soooo much for this video! You rock! 😊

[@youtres1tube1]

Thank you for sharing this. I was hoping I wouldn't have to replace all the inside. It was just calcium crumbs making it now seal good and running everyone once in a while for a short while after done flushing. Thanks for the very helpful video!

[@URTechDotCa]

Glad it helped!
