Alright, if your Kohler toilet's been running constantly or flushing weak, the canister seal is probably shot.

Each seal has an inside diameter of 2-5/8 inches and an outside diameter of 3-3/8 inches – that's the exact size for these canister-style flush valves.


Installing is simple – just pop off the canister, swap the old seal, and snap it back together.
