KOHLER 3" Toilet Flush Valve Kit, Black, Compatible with Kohler Wellworth toilets, 3" Canister with a 3" Outlet, GENUINE PART 1069722

Works perfectly. Make sure it is the right one (check the model number on the inside of your toilet tank)

So, my toilet tank was leaking into the bowl - so fast in fact that you could watch the water level go down after it filled. I first tried replacing the flush valve cannister seal but it didn't stop the leak. Next step was to replace the whole flush valve. This kit contains everything you need - the flush valve with a cannister seal already on , the red gasket that seals the bottom of the tank already on, and the big tank to bowl gasket. You don't need anything else. The included directions are good - they cover removing the tank and flush valve and installing the new one. There are some good YouTube videos out there as well. The hardest part was removing the large nut that connects the flush valve to the tank. When I first tried it with an oil filter wrench around the nut and slip joint pliers around the shaft, I couldn't budge it. So I sprayed some WD-40 between the nut and the shaft and let it soak in awhile. That did the trick and I was able to remove the nut. The rest was easy - just take it slow. While I had the toilet disassembled I replaced the fill valve as well. The toilet now works perfectly - no leaks. This kit is a great buy and fits great - much better than calling a plumber. I'm happy.

This item is of good quality and value. The seal is good, easy to replace. Seems durable so far.

I didn't know if the tank to bowl gasket or the flush valve gasket was leaking, plus my flush chain kept breaking anyway, so I just bought this and replaced both. Now no leak, and nice flush! The valve is super slightly different from the original - the part you attach the hose to to shoot the water in is a little different. It worked though. I was not able to get the giant nut off, so I used a Dremmel and cut it off. This was extremely frustrating. In an ideal situation, they would maybe include a giant wrench tool plus a way to hold the cylinder in place while you turn it (I have an oil filter wrench and CLR'ed it and WD40'ed it, but was unable to keep the cylinder from spinning). So between these things (plus, come to think of it, the fact that the original chain kept coming loose inexplicably) I took a star off - but really it's good, it's working.

If you measure the base of your existing flush tank opening and Compare with this, that’s all was needed to put this in. Excellent quality and no parts missing.

Plug and play, exact fit.

This worked perfect! Saved me a lot of money too!!

Replaced all the inner pieces of my existing toilet rather than buying a new one. Worked out great. The origional piece was siezed on and had to be cut off but the new piece was easy to install and works great.

Parfait. Facile d’installation

Bonne qualité mais dispendieux

With this product I was able to fully rejuvenated my Kohler toilet. Installation instructions accompanying the product must be followed to the letter to avoid water leaks but when followed installation is a breeze. You will need a large spud wrench or a set of large channel lock pliers for the removal of the old and installation of the new part. I was originally told by a big box store that repair parts were not available for the Kohler piston flush toilets in Canada, so I facing the installation of a new toilet. It was quite a relief to find Amazon could supply the needed repair parts.
