The toilet tank seems to be working well. The only issue it makes too much noise when you flush the toilet.

Toilet Tank Replacement Part

Meli A.

The parts I received were more than I needed. The hose that feeds water from the tank to the toilet is too large to fit in the hole. The toilet does not fill up properly, I have to stick my hand in the tank and force the tube into the hole, so that the water in the tank will flow into the toilet. A real problem!

Not great, to expensive

Great product, great customer service, and very happy customer!

All-star company with awesome product!

Exactly what was needed and described- The hose is a bit large and stiff, you may need to use a different one.

Exactly what was needed and described

Product worked well. Good fit. Straight forward installation. Connecting tube for bowl rinse stiff but manageable.

Kohler flush kit DIY

I had to do some fitting on the line that supplies the water to bowl as the tube would not bend as far as necessary

Modification

Best quality.
Before i changed 3 times, not good.
Bought from Kohler, now it is perfect.

Perfect

we did not buy a conversion kit, because it did not fit our very old Rochelle toilet, but bought an old kit that must have set on the shelf for years, because the gaskets were very old and leaky, but it works fine now after fixing the gasket leak.

Old Rochelle toilet

Paige S.

The toilet is 45 years old and I thought we were lucky to find a replacement valve, etc. There is really no tank to speak of...the height of the unusually small reservoir is roughly level with the top of the seat. The net of it is there is no room to work in the tank. Was able to replace the float valve but the flush valve/overflow that the flapper attaches to is attached to the bottom of the tank with 3 screws that you can't get to, not to mention that too much force could break the tank. So, the old flush valve/overflow didn't get replaced and then the new flapper that came with the kit didn't fit the original flush valve/overflow so I had to buy a kit at ACE which had a flapper that fit the old flush valve/overflow. We'll see how long it works until it doesn't...then I'm replacing the toilet. 5 stars for having the replacement kit for a 45 year old toilet...1 star for design that is unfriendly to people working on it...average 3 stars.

1B1X Tank Conversion Kit

Purchased to replace leading fill valve in old one piece Kohler model.  Took two days to install.  Could never get it to stop running and wasting water.  Shut off supply line and ended up ordering Kohler replacement.  $1112 plus shipping vs $182 for the replacement fill valve which never worked right

Great promises
