KOHLER GENUINE PART 1188998 2" Toilet Canister Flush Valve Kit

My toilet works properly again no leaks and noises any more.

Works great. Just the right size

So…. I technically ordered the wrong assy. But every part I needed was exactly correct. We have 3 Kohler Memoirs toilets, all 12 yrs old, and the flush valve on one was seeping.I purchased just the silicone seal, and filler riser at Home Depot and spent about $20.Really easy to service, so I ordered this kit which included 2 complete sets. BUT, it’s for a 2” throat toilet. Even so, I didn’t need to replace the flange that goes through the porcelain tank base. And everything else was a direct replacement. Very happy to have saving a bit of money, and replaced everything that makes up the flush valve..:

This works great and is very simple to install. It replaced the same one installed 12 years ago in a highly traffice area of my home. I highly recommend the product. The ony recommendation would be that they include a wrench for removing the nut on the existing unit (holds the unit to the tank) is hard loosen/remove.

Was the correct replacement item I needed, fit perfectly, the constant running water is no more

I have two Kohler Highline toilets, both bought around the same time, where one came with the older style 2" flapper flush valve, and the other a 3" canister one. The canister works so much better that I'd tried to find one for a 2" toilet several times but couldn't. In need of replacing the fill valve, I decided to search again for a 2" canister flush, and to my surprise found one. Having just installed the Kohler fill and flush valves, they work great. What I like about the canisters, is the simple design and no more replacing leaky flappers.

Perfect replacement and works perfectly

I wasn't sure if it was the right part, but this was a direct fit for my Kohler toilet. I had no idea what the original part number was, as it was not on the part I removed. (However, after I finished the installation, I found that the part number was listed on the BOTTOM side of the TANK LID.) To order, I just looked at the part I removed and matched it to the closest picture on Amazon. Fortunately it worked. Originally, I tried using the numbers stamped in the tank to order the flush valve, but some numbers were faded and illegible. Besides, they weren't the correct numbers anyway. After a quick tutorial on You Tube, I was able to replace the flush valve. It DOES require removal of the tank from the toilet. However, it only required the removal of two nuts (with washers) and disconnecting (unscrewing) the water to the tank. It's pretty straight forward and I'm sure the average person can do it. The only advice I can give is to have a very large pair of slip pliers, or use a plier type oil wrench (as I did) to get the very large plastic nut (about 3 inches in diameter) off the bottom of the tank to remove the flush valve. You'll understand what I'm saying once you remove the tank. Good luck and it works great once it's installed!
