Review on 🚽 Kohler Genuine Part GP84995 Flapper (Hinge) - Multicolor, 2-Inch by Stephen Cernatescu

This comment applies specifically to the Rialto and San Raphael toilets. These toilets have a somewhat unique flush valve that sits fairly close to the back of the cistern. Cast-in rod dampers are difficult to install. When you push the rod, you may hear a crackling sound. This is the sound of a slow leak that causes your toilet to fill up several times a day (or more often). You have just broken one or more of the 3 plastic tabs holding the flush valve in place. This one-piece design exists because DIYers kept breaking flush valves. Since they did not know the cause, they considered the flap to be the cause, although it was actually a flushing valve. Pros don't mess with flaps on these toilets. For another $10 they replace the entire purge valve. Avoid one-piece molded parts in valves. Either use this or replace the entire purge valve. The flap works faster because the washer on the flush valve is difficult to install and often needs to be squeezed during the day.
