Genuine Part Gp1059291 Canister Seal

We had a bathroom renovation two years ago and the new toilet had a canister flush valve. I heard the sign of a flapper valve leak, spontaneously refilling, and discovered the canister in its place. I watched a clip on YouTube that explained simple maintenance of the canister. I ordered this part and when it arrived it took just a few minutes to replace the o-ring. When I turned the water on, the spontaneous leak was gone.

Very easy to install, no leaks!

This was a perfect replacement. Don’t gamble and buy one of the off-brand replacements. Save your time and money and buy OEM.

Overhauled my toilet due to hissing during refill. Since I was replacing my fill valve figured the canister could use a new seal too. Replacing the seal took about 5 minutes after watching the Kohlers video. Hardest part for me was disconnecting the chain which wasnt cooperating lol. I cleaned the old seal residue from the canister and where it seats to and installed the new seal, now its good as new.

My water bill was going up. I thought time to replace flapper but my Kohler toilets didnt have that. Plus one toilet took a lot of pressure to push down handle to flush. Kohler said that symptom was due to an old flush valve seal. I replaced two toilets that had the old red flush valve seal. They were stretched out. One of the toilet was easy to twist cylinder tube and install it. The other seemed like it would crack so I did as one viewer suggested and just slipped it on and pushed it down the black cylinder tube. Of course the purpose is to save on water usage by sealing off the water when not in use. I am waiting to see if my water bill goes back down. If not, time to put on my water detective hat again.

We have relatively new Kohler toilets, and none of them work very well. The biggest problem of all, however, has been these O-rings wearing out. Each toilet has one, and so we keep a few of these replacements on hand. Watch a YouTube video or two to see how to remove the old, worn-out O-ring and install this new one. Be patient, and be careful to not force any of the parts when taking them apart, because they all are made of cheap plastic. Remember the old days when Kohler built everything with iron and steel parts?

ALL GOOD

Easier to install than the whole can assembly. If all of your plastics are still in good shape, but the flusher sticks or the water is always running, the this is the easiest fix.

The toilet valve was going on for about 30 seconds every half hour all day and night. I’d get up an hear the toilet running, then it would stop. Read about replacing this seal, a 10 minute job, and now the toilet works like it should. I noticed that the old seal had developed a small bubble which allowed a tiny amount of water to leak, eventually triggering the valve to fill the tank. This seal fixed the problem...no plumber needed!

First, I bought a cheap 3rd-party seal that was supposed to be compatible, but it leaked because the diameter was actually wrong. Then I bought this official Kohler seal, and it works great.
