Replace the Kohler Canister Flush Valve Seal - Kohler Toilet Running

I show the step for replacing the flush valve seal on a Kohler toilet. If you have a Kohler canister style flush valve and the toilet is running, in most cases it it just the seal on the flush valve.

And THAT'S how you do a video. No unnecessary gabbing, no crappy music, no B.S. Great info. Subscribed.

Finally a video that gets right to the point and under 2 minutes!!! WTG.

[joepearson]

Thank you. You saved me from forcing and breaking something. It took me all of 35 seconds after I saw this video.

Doing some research I found several places that told me to call a professional to do this because the tank needs to be taken off.. You just showed me how to do it in less than 2 minutes with the tank on!! Thank you a million times!!

Thank you for this video ! My partner wanted to wait until one of our dads had time to come fix our toilet troubles, but I knew this was something we could do ourselves. Just needed a straight forward demonstration from a helpful stranger.

Terrific video, direct and straight forward without a lot of gabbing. Saves me time and money purchasing more than what is needed. Thank you, great video. I learn a lot from these videos.

You just saved me about $15 and a lot more work to replace the complete valve, thank you!

Another tip... mine apparently was very old and crusty, and when I tried turning it counterclockwise it didn't budge, and felt like it would break if I tried any harder. Living in the country and being over an hour from the home store, I wasn't willing to risk that. I just disconnected the flush handle chain and removed and installed the new seal with the flush valve in place. The seal easily stretched enough to be worked around the flush valve cylindircal body.

I went from thinking "I have to go to Home Depot after work today" to "I just fixed my toilet" in 5 minutes. 2 of those minutes were spent watching your video. Thank you.

Thank you so much for this amazing tutorial. It took me 5 minutes to do. The seal was still in good shape, so it only needed to be re-situated. The best part is that I didn't have to spend any money on parts, or worse, on a plumber to do something so simple!

[k.j.hastings]

Thank you. My toilet looks to be the same model (comes apart at base vs top) so this video saved me $50 by doing it myself vs. having a plumber come out. I had tried using other videos but those show just the top coming off so was reluctant to try a lot of pressure and possibly break the stem.

One hint - lift the canister up and take hold of the stem at the base and twist instead of grabbing the top or reaching into the canister. I did that and mine popped right out.

4 years later…. This video is still saving lives 😂 thank you sir!

[jamesratliff]

This video was exactly what I needed. Thought I was gonna have to unscrew the bottom of the tank. Thank you!

[waterdoglures]

Thank you sir! This was exactly what I needed. Wasn’t sure how to remove the center post without breaking it. Great job. 🙂

Wonderful, straightforward, informative video on how to change a Kohler Canister flush valve seal! Took me about 5 min. to do so! Once I figured out how to remove the canister, changing the seal took less than 20 seconds. I probably spent most of the time trying to disconnect the chain hook and reconnect it! Thank you for saving me time and money!

[cindyquayle]

Thank you so much for this clear and concise video. I have been putting up with two Kohler toilets that constantly fill from what I am sure is just the seal. You just saved me the cost of calling a plumber, or the thought of trying to replace the entire assembly when it isn't needed. Awesome!

[WilliamSymionow]

I like how you made it short and sweet. Other videos take 20+ mins to say the same thing! Thanks

Additional input: You can try cleaning that seal (and the ring it sits on when it is closed) with a dish washing brush. Water deposits collect on both and scrubbing them off sometimes works. You can also remove that rubber seal, flip it over and re-install it so you have a brand new side facing downward. They are reversible! That worked for me after cleaning it eventually became ineffective. If none of that works just pay the $7 for a new gasket and follow the gentleman's instructions. I use Clorox toilet tablets in the tank and I'm told they can eat away at the flushing mechanism, but to me it's worth it to have a little bleach in the water with every flush. It prevents bowl stains and makes the whole bathroom smell clean. If that means I have to replace the gasket a little more often so be it. As you can see by the video it is super easy and takes all of two minutes :)

Great instructional video, short and to the point. I would suggest to attach the chain first before you insert the canister - it gives you have more room to work.
