Bests & Worsts Reviews from Amazon

Toilet seat can't come down with this attached. See pictures attached. Water flow rate is much too high. This is going to be one giant mess even if I get the seat to work. Same fitting problem on a second Kohler toilet. I think the issue is with the downward curve towards the center on Kohler seats, hits the flat part just above the nozzle. You may have better luck if your seal is flat at the bottom.
