Replace Kohler Toilet Gasket/Seal and Stop That Leak! (Five Minute Fix)

Gasket ($6.99): amzn.to/2xxNmlk
Canister assembly: amzn.to/2xwM5eA
Got a Kohler toilet that won't stop running, that flushes intermittently, or that leaks (slowly or quickly)? Chances are good that five minutes and a $7 replacement gasket will take of the problem for you. It's easy and doesn't require tools.
This fix is for toilets like the Kohler Wellworth series.
Lots of you suggested removing the rock. It was there when we bought the house and didn't seem to cause any problems, but I've removed it just to be safe. Thanks for sharing your reasoning, folks!

Just completed gasket repair of my Koehler toilet with your directions. I am a female 82 years old and if I can do this anyone can. Thank you! The last time I had a plumber do this it cost me $95.00. My cost was $9.00 for three gaskets.

[@adkpiper]

Nice work! I'm so glad you were able to fix it yourself!

[@jaclynwakita5507]

Me too!! Thanks so much!!!!

[@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

[@adkpiper]

Good tip! Thanks for sharing!

[@juvieguy]

I followed your video, perhaps the most complete and clear instruction video for this, and replaced my badly worn gasket in about five minutes. I was ready to call a plumber before your video. Thanks for saving me a lot of money on a very easy repair!

[@adkpiper]

I'm so glad you were able to fix it!

[@kev6216]

Grab from the bottom when twisting the quarter turn if it's too tight from the top. Great Vid!

[@1516jen]

First time I've fixed something on my own without having to hire a professional. Thanks so much!!!!

[@adkpiper]

Well done!

[@lindamcfeely7994]

after nearly 6 mos of having the part and my husband not taking the hint, you saved me from calling a Plumber. Easy Peasy to repair. Thanks for the video

[@adkpiper]

You're welcome! Glad it helped, and thanks for subscribing.

[@m7floyd]

I bet you also paid a lot of money on water bill.

[@lindaarmand2142]

Your video was really helpful! We had a toilet that started running late this afternoon. After watching your video, we flipped the canister over and pulled off the gasket that was original to the toilet which was right at a year old. It was a red one, and it had little pimple like bumps on its top and bottom. Don’t know if this is the design or a defect. Anyway, my husband took it to Lowes and bought the $8 replacement and put it on. It worked like a charm. So far the toilet is not running and there is no leakage. You came to the rescue on a Sunday evening. Thank you sir!

[@GoldenFosterMom]

Thank you for posting this! $8 and a 10 minute fix. You saved me $100 minimum plumber call!

[@shabnamsultana1920]

I didn’t think I would find a video on changing the seal, but this is great! 👍🏻

[@spencerbishop6858]

Very helpful, thank you! We had two leaks like this in our house simultaneously (Kohler toilets installed at the same time) and I thought it would take me hours to remove tanks and replace everything when I knew it was just the gasket, but I didn't know who even produced the parts I was looking at (I didn't install the toilets). 5 min video and 15 minutes to replace both gaskets is probably the easiest fix of anything I've ever dealt with!

[@blainegoocher2958]

Great job. About the easiest fix I have ever seen and I can't believe I had it down at the bottom of the Honey Do List.....Thank you Sir. Blaine Goocher Sr.

[@Sojourner_PNW]

I've been putting this off for months. Your video helped and showed me how to replace the gasket. Thanks so much.

[@adkpiper]

You're so welcome! Glad it helped!

[@donnaroom1504]

Thank you Hollis, you are my hero! Worked as you said it would. Appreciate your adding the fact that it's important to wipe around the seal seat in the tank (debris from the old rotted seal was caked on it) --- no one else on youtube, even from Kohler!, suggested to do that and it is so important.

[@SKYGUY1]

We bought our house 10 years ago and installed the new Kohler elongated toilet w/ the canister flapper. It lasted about 9 years and 10 months. Bought the seal yesterday and thought I'd check youtube for surprises. That's much easier than replacing the old flapper style. Thanks.

[@stevedietrich8936]

Excellent video with step by step instructions, as well as the part number you need. Easy fix and good job. Once I had the gasket out of the package it took about 3 minutes to remove the old gasket, place the new one, and reassemble everything.

As a skeptic, this video was easy to follow and actually worked. Thank you!

[@robertwilliams6218]

I just changed the gasket myself and I know I had to have saved a ton of money. I wasn't familiar with this type of toilet since everywhere I have lived had older toilets but this is so simple and easy.

[@kellyfitzpatrick4355]

Thanks! I figured out this was leaking and thought I had to replace the whole valve -- and was wondering where to get a 4" open end wrench to remove it. KZbin to the rescue (again) all I needed was a seal.

[@gaypreator8547]

Thanks for posting this video. My toilet mechanism - exactly this. Makes me feel like Superman when I do these. I’m going in in the morning.

[@bcvahsfam]

This was very helpful to me. I was able to fix our toilet that had been running for quite some time. You described the problem and solution very simply and clearly. My toilet is fixed and I had the satisfaction of doing it myself. I'm not sure I would have tried without seeing this video. The instructions on the seal package were not good. Thank you so very much!!

[@adkpiper]

You're so welcome! I'm glad you were able to fix it yourself!

[@loulouncmtn]

Bam...it took me less than 1/2 hour to change out both! Thanks for helping me save some money, plus I get the satisfaction of having done it myself!! As a woman, that’s a huge plus.

[@todddahl1123]

Yay! No more constantly running toilet!!! And it only cost me about 8 bucks and 10 minutes of my time. Thank you!

[@adkpiper]

You're so welcome!

[@mikeknowles8017]

Thanks so much!. One of the toilets in our house had this exact problem and I was not familiar with this type of toilet mechanism. Thanks to this video I took care of it in minutes.

[@NYSESTRA]

Thank you so much! Great instructions wicked easy to follow. You saved us a call to the plumber and taught us something.

[@cvirtue]

Thank you for link to the part on Amazon; I searched beforehand but could only find the Kohler double pack, and don't need two!

[@stephendemeo1767]

My Kohler slow leaked out of the box but at the time I thought it was my new bidet. Tried quite a few things, spent a lot of time with videos, and over a year later fixed it with a simple gasket. Now why did Kohler sell a toilet with an inferior gasket? Who knows but I am sure it builds up a lot of customer resentment. Thank you adkpiper for allowing me to fix this long standing problem.

[@patt8565]

Thanks for this video I was going crazy trying to figure out why my water kept running. I only had the toilet for a year in a half. That’s what the problem was the seal bubble up on one side and that’s why it was leaking. Your video was very helpful.

[@rickschindler5384]

I am a fumble-fingered klutz, so it took me closer to 15 minutes to replace the seal with the help of this exemplary video. Well done, and thank you.

[@adkpiper]

You're welcome, Rick, and thanks so much for your kind words!

[@MD77SA]

I guess I needed to turn it harder. I also tightened the handle lever after replacing the seal but it was too tight, resulting in the entire canister coming off with the first flush. I put it all back together and tightened the flush lever again and it is working. Thanks for your video. Very helpful. This was my first one.

[@MD77SA]

I meant loosened the flush lever*

[@lovernedwards5888]

Thank you so much… I have watch over five videos and your video help me to start and finish the job. Thank you so much.

Great video, akkpiper! I replaced the rubber seal for my Kohler toilet that kept having "phantom flush" issues and now it's quiet like a good toilet should be. :)

[@MarcoMangiare]

This saved me a $200 visit! Thank you so much. It took two weeks to get the part because Home Depot, Lowes, and Amazon were all sold out 🫤

[@nimmagupta65]

An excellent explanation how to replace the seal in Kohler toilet. Had the same problem today & after watching this video I was able to fix it in 10 Minutes. Thanks so much sharing this vide. We need more people like you who can explain step by step & an easy way.

[@adkpiper]

Thank you so much for the detailed feedback, Nirmal! I really appreciate it! Thanks for subscribing to my channel.

I found your video very helpful. I had the water turned off for two weeks waiting for the gasket. I replaced it and turned the water back on but the tank won’t fill? Nothings happening

Great job explaining how to do the replacement. You saved me from hiring a plumber!

[@adkpiper]

I'm glad it helped! Thanks for subscribing, if you did!

[@kenfuciusfpv2800]

Thanks! I wasn't sure how to get that thing lose. Same here, I bought my home and the toilet tank was leaking into the toilet for just a few seconds every once in a while. It looks like the previous owner had all kinds of calking or silicone or something in there trying to fix it. I took a hard plastic brush had brushed all that out and followed this tutorial. The toilet is as good as new.

[@nicholasnoble7762]

Thanks for sharing, was wondering myself whether liquid silicone might be a better fix than replacing the gasket. Sounds like replacing the gasket is the way to go!

[@stevemannion8341]

No disrespect to ADKpiper, This incredibly informative video took longer to watch than actual the seal replacement. Think it took me a minute and a half. I was scared I was going to crack the center piece while trying to unscrew it. That was my biggest fear. Awesome job sir!

[@adkpiper]

I'm glad it worked for you!

[@stevemannion8341]

Here's a tip you can share. I noticed prior to having repair the gasket the Trip lever (flusher thing) was sticking. It became more difficult to get the flush to activate Guess that was the heads up.

[@mayssm]

Running into this myself. Never seen a system like that before. It looks more complicated than it actually is. The red rubber seal on mine is becoming very loose and floppy, so it's coming off the cylinder very easily. Just ordered the part from your link!

[@beansha]

Thank you so much! I just replaced mine and followed your video for the instructions which were great.

[@edgrossman9492]

[@dougvanderberg471]

Thanks so much -- I would never have fixed this without your video -- Twisting off the top was sketchy -- It seemed like it was going to break. Fairly easy and just a few minutes over 5 -- Our gasket looked like a war zone compared to your's.

[@WeatherFan2009]

Thank You. I thought it was going to be a massive repair. It shouldn’t be bad now.

[@brianbanks3044]

I recommend grabbing from the bottom of the plastic piece to twist it out of the base..mine was pretty tight and I am sure it would have snapped if I continued to twist it from the top like you did....I did both of my toilets at the base and it took all of 5 minutes...thanks

[@adkpiper]

Good suggestion!

[@kev6216]

Brian-good call! mine felt like it was going to snap too but if you grab and twist from the bottom, it came right out. Thanks!

[@nicholasnoble7762]

@adkpiper That warning of his about where to grip the canister shaft when twisting it should be mentioned in your video description, sounds like lots of people are saying you should grip the bottom to avoid breaking it if you dig through the reviews and comments for this gasket and canister.

[@sassygrasshopper1215]

Thank you very much I have been having this issue for month with no solution now it's working great again

[@markanthony4207]

Thank you. Worked like you said. I was nervous about breaking the valve but your comments helped.

[@andrewbuckley8452]

Thanks, It worked fine, I bought one on eBay, The original was red and the yellow replacement was slightly smaller with a more snug fit. So far doing great.

[@Piruluz]

You saved me a lot of money. Thank you. I did exactly what you did and it worked.

[@udavidism]

The rock you have in your toilet to save water is mostly below the empty water line, that only saved water the first time you put it in there. If you want to save water put a quart or even larger sized water bottle full of water that extends all the way to the top of the full water line, that will save you water. Great video!

[@lindahicks9932]

Thanks - I feel like such a handy girl following your instructions.

[@bellavita3097]

I am replacing mine today I got the same ring at Lowe’s for $7.88 here in Michigan but my seal was pink my Kohler toilet is only seven years old and it’s completely deteriorated, (I use no chemicals ever) yours looked in much better shape and you had a much easier time clicking the canister off the other videos I watch they had a hard time they had to click it twice to the left to get that canister off without breaking the plastic pieces. Also the chain length can make the toilet run as well if the seal is OK.

[@MrBornfisher]

Thanks, that 1/4 turn had me stumped. They should refer to this video on the package!

[@onlyspicekitty]

thank you for this Info , i will need to do this myself, and was unsure on how to replace the Seal !

[@whalekock]

Helpful hint: flip the exising gasket before you go to the store and buy a replacement. It will buy you time.

[@jjscalifornia5086]

As a cheapskate, that was my solution after watching this video. The seal may last as long on the second side as it did on the first side and delay the need to spend $6 for another 8 years.

[@tonyspark]

Any update on flipping the gasket? 😅

Do you also flip your underwear and wear it for another day?

[@royrodroguez1167]

Thank you for the step-by-step buddy. But just to share when my random fill started. Was a little after I started to add the clorox toilet tank tabs. I think that those things weakened the rubber gasket on this type of tank style.

[@adkpiper]

That makes sense! Thanks for sharing the tip.

[@nicholasnoble7762]

Same here, added Clorox tabs and the issue started about a month later after years of problem-free functionality. There's a warning in the tank against using those, but I guess that's also why the new gasket is advertised as chemical resistant. More than worth replacing the gasket to be able to keep using the tabs!

[@dimk5207]

This is the better repair for this situation, and the cheapest. Product available at Lowes. Reasonable price and if you have hard water this could be a constant problem. A monthly cleaning would also assist.

[@jonathanlerner7283]

nice vid. very helpful. however, your toilet already had water savings built in. it's probably a 1.8 gal per flush toilet. any less water in that tank reduces the flow in a sewer system that was designed for a much larger flush capacity. you cause problems down the line because the slope in the pipes doesn't move solids as well. my advice? remove the rock. let that 1.8 gpf push the solids where they need to go to get processed. one of those unintended consequences of water saving regulations

[@pdbandit1]

I had my toilets replaced with this brand 3 - 4 years ago, 1 has never had a problem and the other started having this problem after a year or so. On the one with the problems the flush handle would be noticeably harder to push down when it was leaking, a new gasket seems to have fixed it.
