Toilet Flush – Increase Flushing Power – Kohler Canister

For toilets with 3 ¼” flush valves, you can noticeably increase the power of the flush by holding down the handle longer.

I talked to Kohler and the valves are set at the factory to limit the volume of water used. The only things you can change are the height of the water in the tank and the slack from the handle to the connection to the flush valve. Once you have adjusted these to the best levels, the only thing you can do to increase the flush power, is to hold down the handle longer.
