    We just installed a new Kohler Cimarron and it has a slow leak where the tank connects to the base. We took it apart 3 times and reconnected to make sure it's seated correctly. We called Kohler and they sent us a replacement kit for the tank connection. It still leaks! Please tell me what we could be missing before we rip it out and install a not-Kohler toilet!

    Normally it's just a matter of making sure everything is clean.
    No putty, no caulking.
    I sometimes check smoothness and use some emory cloth on the china if I feel rough spots.

    If you have a flexible supply to the tank, make sure you have no tape on the threads. Those will come with seals at both ends.
    New toilet, new flex connector.

    Thanks. We gave up and installed a Toto. Got our money back from Kohler. It appeared that the porcelain hole was defective and even if we could get it to stop leaking, it would always be a concern and something to keep checking. We're very happy with the Toto!
