Kohler K-1188999 2 in. Toilet Canister Flush Valve Kit

[This review was collected as part of a promotion.] Kohler makes finding the correct part easy. Just look for the model number in the tank and enter it into the Kohler site. The part shipped fast and was well packed. Removal of the tank was easy with only two bolts holding the tank in place. Once out you only need a large Crescent pliers to remove the old valve and install the new part. The valve comes with all new seals ensuring that nothing leaks once assembled. The new valve operates smoothly and is very quite during the flush and fill cycles. Over all I recommend replacing this part by the end user to save money and improve the operation of the unit.
