Customer Questions & Answers

how do i know if the seal is leaking or if the fill valve is the problem?

Hi. Hoping to make a repair to a toilet that will not fill without an expensive plumber visit. The toilet tank is not filling with water. The water just runs and runs and never fills. It is a canister style toilet flapper with a fluidmaster 400 antisiphon flush valve. The toilet is a 2007 Kohler class 1033131 Is it likely that it is the seal that is leaking on the canister or a problem with the fill valve. I feel qualified to replace a seal. I've don't that successfully on flapper style toilets. Thank you for any advice!

If the water runs constantly, or nearly constantly, without overflowing the cylinder top, then the lower cylinder seal is leaking and needs to be replaced.

how do i remove & install this washer?

Asked by: Anonymous
The inner piece with the circle on top (inner piston) can be gently turned 1/4-1/2 way and it will come out. This frees the cylinder so you can remove the old and replace with the new gasket. Expand the picture that I attached and you will see at the bottom of this piston there is a 4 point cross. That is what you will turn slightly to release it . There is also a you-tube video about changing a canister style toilet gasket. Hope this helps

Why won't the canister seat so the tank can fill?

I bought a seal for the bottom of the canister about a year ago and it has worked fine since. Now suddenly, the water keeps running and the tank wont fill. It seems the water weight in the canister is not allowing the canister to seat fully. I can see more than just an air gap by looking from the top. What is the cause and solution??
Asked by: Ray
You may have accumulated some particles or 'gunk' on the sealing surface that the gasket sets down on, or between the gasket and the cylinder. Try removing the gasket and inspecting the area it seats into on the cylinder for accumulated foreign material, or bits of the decomposed old gasket. Also, wipe down the lower flange surface (attached to the bottom of the tank) to make sure any stuff that settled there is not interfering with the seal when the cylinder falls back down after a flush. The inside of the cylinder should not have any water in it after the tank fills. The pressure of the water on the outside of the cylinder (counter-intuitive, I know) is what holds it down on the seal. If the cylinder is full of water after the tank fills, then the drain holes in the bottom of the cylinder are clogged and it will not seal well.

Seal for all Single Flush Class 5 and Class 6 Canister Toilets is rated 4.6 out of 5 by 235.

The old red seal had gotten soft and tacky. It would often get pulled off and then the toilet would run for hours. The effort required to actuate the flush handle was getting increasingly higher. After installing this new seal, the toilet now flushes with less effort and the seal stays in place. This appears to be a an improved material rather than just a simple color change. Time will tell. The previous seal had been in service for about 4 years.

It was reasonably easy to install if you read the directions, but the best part about this seal is that it stopped the toilet from making the hissing sound it would when it periodically would refill the tank. This has stopped my wife from complaining about the hissing sound. That has increased the peace and quiet in the house. So, overall, this seal will make your house 37% quieter. I highly recommend.

The seal is easy to install once you have removed the canister from the toilet tank. Be sure to turn the water off (either at the supply or by securing the float in the "off" positlion.) Flush the tank to remove the water. To remove the canister, rotate the shaft in the center of the canister counter-clockwise; the rotation may take more force than you expect. Before installing the seal, clean the canister where the seal goes, and clean the seat in the bottom of the tank.

The packaging really caught my eye, and the price was too good to pass up. It was a "cinch" to remove the old gasket, and replace it with this one, stopping the constant leaking in the toilet tank. Thank you Kohler for a great product and thank you Home Depot, for this wonderful shopping experience!!!!

Toilet was flushing too hard...handle almost impossible to flush...replaced this seal on the bottom of the canister and reassembled it and it was like having a brand new toilet...flushed nice and easy...when this seal starts to go it gets gummy and creates to much suction making it hard to flush..so for a $6.00 seal to fix is wonderful...only took 15 minutes to fix as well

Also the original seal was sticking and the toilet was was becoming difficult to flush, requiring more pressure on the handle. This yellow seal replaced the original red seal and was very simple to change out. The leak has stopped and the handle no longer sticks due to the sticking seal.

I had a toilet with a slow drain and though i needed to replace the whole canister. Fortunately, this seal is a direct replacement for the original seal. Word of advice, when you replace your original seal, make sure you clean off any pieces of the old seal on the canister and the flange attached to the bottom of the tank. My original seal was breaking down and the new seal wouldn't have a good seal between the canister and the flange without cleaning the original pieces off.
