Korky 2011BP Hinge Flapper For Kohler Toilet Repairs - Replaces Kohler Parts 84995 and 1000490 - Made in USA, Red

Our water bills have been super high lately. The water company informed us that we may have a leak, though we couldn't figure out where. When I heard my basement toilet constantly running, I took a peek and realized that the flapper was basically disintegrating and was letting water flow into the bowl. I got a "universal" flapper from Home Depot, which was supposed to fit my Kohler Santa Rosa, but it sadly did not. This is labeled as a replacement part for the Santa Rosa's flapper and it fits perfectly. Super easy to install and works great. No more running toilet. Also, props to the seller for getting this shipped so quickly.

Excellent product. Fitted correctly on my toilet without issues.

There are millions of different flapper valves. Brick and mortar store had one that looked close, but not quite the correct fit. Used the brand name from the incorrect product packaging to track down the correct model and found it on this site. Delivered promptly, works well and no more running water in the middle of the night !

Works great!

This is not the first time I have used this item and what I have learned is that you have to give it a about a week to stiffen up and really work the way it is supposed to. During the first week, the flap may not settle over the pipe correctly and water escapes so the toilet keeps running. Next time, if I remember, maybe I will soak it in water for a week before I install it and then it will work great right from the start. After that first week, it is reliable and works consistently. Also, I had trouble when it is brand new getting the thin back piece to fit into the correct groove, but after a week and trying again, it clicked in securely and that is probably what made the most difference in its proper operation.

The part fits perfectly and is easy to install. Helps lower the increasing water bill.

First of all, if you're going to order this, make absolutely sure that the part to be replaced is a "shark fin flapper". This is slightly oversized (the opening is maybe 2-3/8" wide and not a standard 2") and the Kohler overflow tube (where the flapper mounts on L-shaped pegs) will be rectangular-shaped. If it doesn't fit, don't blame Lavelle or Amazon just because they say it "may fit" certain model names. Kohler is well known for building the same model names/numbers with different internal parts. If you look at the original flapper, it will be pretty obvious is this is the proper replacement. There are no other flappers like it with a triangular fin at the top like this one. Compare the photo to that of the part to be replaced, and you will know.Additionally, this is functionally identical to the one that Kohler sells as their own replacement part - currently model# GP1078440. At least at one time (if not now) Lavelle (Korky) made the ones that Kohler sells, although Fluidmaster could also be producing and/or selling a functionally identical part. Kohler doesn't make most of their the internal parts - they source them from companies like Lavelle and Fluidmaster, although some are designed specifically for Kohler and don't fit any other companies' toilets. I remember a time when Lavelle sold this particular flapper directly as "Kohler Genuine Parts" with the Kohler logo and everything. When I bought this one, I managed to find an old one in the garage (still unused and probably fine but the blister pack looks messed up) and the UPC code is identical even though the current version doesn't carry any official "Kohler Genuine Parts" verbiage.

I have been using this product 10+ years and change it almost every 1-2 years. Even though I have to change it every 1-2 years, I have no problem to spend $6. If you use this first time, you may need time to learn how to put it on right place since it's impossible to see the back of main plastic tube. You can touch the back of it to guess the shape. Or you can go to hardware store to see a new one.Nevertheless, it's not this part problem but the toilet design issue. There are several different height you can use and make sure you put this part on proper level height. Otherwise, the flapper will not cover the water drain hole completely. Then leak, of course.If you don't like this kind of flapper, look for other kind of toilet next time. I would do that too since I don't like this style of toilet but I inherited from the previous owner. Anyway, overall quality of this part is great!
