      Q:There is a crack in the back of my toilet tank. The inside of the tank says K-4620-DA, 1.6 GPF. I'm not sure how old that model is, can I still get a replacement tank without buying the bowl too?

      A:  Lottie, my name is Jessica with Kohler Customer Service. I am happy to assist with your inquiry. I do apologize, K-4620 has been discontinued and there is not a direct replacement available; both the tank and bowl would need to be replaced. Thank you for choosing Kohler.

        Answer This Question

        A:  Hi Turkeyrunner, this is Sarah with Kohler Customer Service. I'm glad to address your question. If you have the K-4327 bowl, this will work with the K-4645 tank. The original question referenced the K-4404 tank. This tank, when used with some older bowls, may not be a direct replacement to the K-4645 tank. If you have confirmed that your original bowl is the K-4327, the K-4645 will be a compatible replacement. I hope this clears up any misunderstanding! Please call our team directly at 1-800-4KOHLER for additional assistance. Thank you for choosing Kohler.

          No more clogs...ever!
          I was having issues with my American Standard clogging just about every time I used the restroom. No possible way with this unit. If you want it.....don't put it in this because it is GONE!

          Great features
          This the 5th one we have bought during our house renovations. We noiticed that yyou have to ensure a snug connection between the bowl and base but you can't overtighten the bolts. It's trial and error as the bowl will leak if the connections are loose but take care to not overtighten the bolts!!

          Be sure when you are ordering a tank for your bowl that they are compatible. We ordered this with a bowl as they were from the same collection and the website listed this as a suggestion to go with the bowl. Got here after we had already installed bowl and put it on top and it didn't flush at all, found out later that it actually doesn't go with the bowl and ended up having to order one that was $600!! because we couldn't take the bowl out after we set it into the floor and so maybe it may work if it is on the correct bowl but for us it was a huge headache and hope Home Depot comes up with a way to flag your items if they don't work with eachother.

          Once you experience a powerful flush like this, there's no going back to ordinary toilets. It was very easy to install and so far I didn't have to make any adjustments to the pressure tank.
