I never look at model numbers when I replace my flapper I just buy the same one and it works. I bought it some time ago
Yes, this is a direct generic replacement.
Our toilet is a builder grade for older series and the Kirby was our best bet. The store rep that I spoke to on the phone was very helpful determining the compatibility.
I just reviewed this flapper and had the same issue, 2x so far with this product. They both failed after a few months of use, in a Kohler toilet where no chemicals or additives are added to the tank. IMO the rubber used in this flapper weakens after being submerged for a few months, to the point the ring itself becomes too flacid and therefore can't cover the drain hole after a flush as it's partially pulled into the drain hole. That causes the water to run continuously until you fiddle with the flapper to make it fall straight on top, without getting pulled in. A stiffer flapper edge, internal reinforcement, or a slightly larger flapper would help but since this failure has occurred 2x so far I will have to look for another mfg.'s product replacement or get one from Kohler directly.
It says it’s universal. I have Kohler toilets and it fit perfectly
Look at the flush valve drain opening in the bottom of your toilet tank. If it is the size of a tennis ball or orange, you require a 2" flapper. If it is the size of a softball or grapefruit, then you need a 3" flapper.
Korky 2" universal flapper should work fine as shown on picture above. They are widely used by the customers as a replacement. I have not experienced any problems with it. B653302F is a Briggs original flapper.
Chuck, the best way to get a match is to take your old flapper to Home Depot and compare it to the ones they have on display.
Thanks for your interest in Korky. You discovered there are some differences in flush valve systems and that toilets sizes can vary. An easy reference is to look at the size of the flush valve drain opening in the bottom of the tank. If it’s about the size of an orange or baseball, you need a 2 inch flapper/flush valve. If it looks more like the size of a grapefruit or softball, you need a jumbo 3 inch flapper/flush valve. The vast majority of toilets on the market are 2 inch (orange/baseball size). The 3 inch toilets (grapefruit/softball size) are a newer phenomenon in recent years. If you have any additional questions or want help with your install, we are here and happy to help.
