Review on Kohler K 4467 0 Wellworth 1 28 White by Matthias Foxx

Nice product but be careful with the instructions. That doesn't tell you much but gives you the idea that all the gaskets on the fastener head are flush with the inside of the tank, but that's wrong and you'll break the tank/bowl trying. Only tighten the three screws firmly, do not try to stretch the rubber seals completely. A solid fastener compresses/expands the liner and closes the hole in the shell even when the fastener head is not all the way down. This was my first time using Kohler's new sealing method and it surprised me because it is not the same sealing method found in most toilet tanks. Once you know it, it's easy to install.
