    Q:can installing new seal improve hard to flush handle l
    by|Oct 2, 2020
    4 Answers
    Answer This Question

    A:  Yes. If the rubber of your seal starts to degrade, it can sometimes get sticky. That can make it hard to lift the canister with the tank lever. A fresh new seal won't have that stickiness to it, so you should get an easier lift from your tank lever. If you have further questions, please call our Technical Support team at 800-528-3553 or email us at sales@lavelle.com. We are available Monday through Friday, 7:30 AM to 5:00 PM CST.

      A:  Yes, the old seal becomes rather sticky, and almost like chewed gum, which causes the handle to feel stiffer to flush. On my toilet it took just a few minuets to clean up the old seal and install the new seal.

        A:  yes. The old valves become sticky and the new valves made it much smoother

        Q:Information in the Specification section is not accurate. It listed both inside and outside diameter of the seal as 3". Is the inside diameter 3"? If so, what is the size of the OD? Thank you.

            A:  We're sorry for the confusion. The inside diameter for the Kohler seal is 2.7 inches. The outside diameter is 3.4 inches. For the American Standard seal the inside diameter is 2.6 inches and the outside diameter is 3.3 inches.

              A:  The gasket does not fit. It is a tiny bit smaller and buckles when installed in my Kohler toilet. The buckles case a leak. I had to return the part and buy a genuine Kohler gasket, which worked like a charm. I suggest Home Depot find a different supplier.

                A:  The package denotes that one valve is for Kohler and another for American Standard but I used both of them in my Kohler toilet and they both fit. There is a good chance that they both would fit in American Standard as well, but not 100% sure.

                A:  Two seals come in this kit. One is for Kohler Class 5 and Class 6 flush valves, the other is for American Standard Champion 3 flush valves. Your Champion 4 needs a different seal. Please consider calling our Technical Support team with your American Standard toilet model number at 800-528-3553 or email us at sales@lavelle.com and we can quickly identify the correct part for you. We are available Monday through Friday, 7:30 AM to 5:00 PM CST.

                    A:  I used it for my Kohler toilet. Package states that the second seal will fit American Standard. I suggest measuring your American Standard flush unit to make sure it is 3 inches in diameter before opening the package.

                    Perfect replacement for Kohler GP1059291 seal.
                    I used it to replace the Kohler GP1059291 seal on the canister drain valve. Works perfectly. 1) The Kohler warning label about not using chemicals in the tank is serious... Adding bleach to the tank water to clean and disinfect it will disintegrate the original seal over time making it gummy and cause the canister to stick to the seat, requiring extra force on the flush handle to separate the two. 2) The Korky replacement "looks" like the same material as the original and may exhibit the same reaction to cleaning chemicals. In contrast, the replacement from Kohler is yellow in color and boasts about being resistant to chemicals. It seems Kohler decided the warning label was ineffective and redesigned the seal using a different kind of rubber (silicone?). The Kohler brand was not available in the store so I got Korky. 3) The Kohler canister flush valve mechanism is made of ABS plastic. Do NOT use acetone to clean off the old seal material - it dissolves ABS.

                    Replacement is easy. Just give the interior post a 90 degree twist and you have access to the old seal. pull it off, and put the new one on, making sure to seat it all the way in the bottom groove. Insert the post into the hole in the bottom holder (a little hard to see the right orientation - I had to use a flashlight), and give it another twist to lock it in. Nice that there are two in the package. Keep the spare in a drawer for 4-5 years until time to replace again (I have two that use this seal).

                    Great replacement part for Kohler Toilet! There are two types of seals in the package, one for Kohler, one for American Standard. Works like original...would be nice if it came with two seals for Kohler instead, but that's a marketing issue. A++++

                    Rubber parts in toilets, like fill and flush valve seals, that are exposed to chlorinated water need to be replaced periodically, as they deteriorate and begin to leak - indicated by continual or periodic running of water into/out of the tank/bowl. In our toilets (Kohler), the flush valve seals like the item above, and the fill valve seals as well (not the item above), tend to last about 1 year or so. I keep a few replacement flush valve seals like these handy for when this happens. Some times debris from the water line gets under the flush valve seal and can be removed correcting the issue, but eventually, the seal will have to be replaced for deterioration. I also keep some fill valve seals handy as well. My only complaint about this item is it contains two types of flush valve seals, one of which is going to be wasted unless you have both of the two types/brands of toilets the seals are for - haven't figured out a use for the wasted ones yet.

                    Went to buy the official Kohler brand seal, but the Home Depot employees couldn't find them. Bought this instead, and it works just fine at a lower price. No idea how long it will hold up, but the Kohler seal lasted 4.5 years.

                    I purchased this product about 2 weeks ago because my toilet kepted running , the tank would drain slowly and than refill again so after checking for the problem I found that the seal at the ceilinder was the cause so I purchased the Korky brand Vavle Seal Kit to give it a try and I was glad I did because it fits perfect, the installation was simple, product well made and he price is right. This seal took care for my problem. I would recommend this product.
