great product

### ⭐⭐⭐⭐⭐ Confirm compatibility by dimensions, not just model numbers
*by L***Z on January 11, 2026*

Ordered this for my Kohler San Raphael (2002). I was happy to finally find a replacement flapper specifically for my toilet model. I’ve been using universal flappers the last few years and they always eventually end up being too large and wobbly for my toilet, which leads to the constant running water issue. My exact model number was listed on the product listing and even on the packaging for this flapper, however it ended up being too small. I honestly thought I was losing my mind and kept trying different ways to make it work… but it’s simply too short. When installed it sits too snug and stays partially open. I tried repositioning it on the back multiple times and nothing fixed it. I can’t leave a bad review for this because the product seems very good quality and it was easy to install. It just didn’t fit. I did however return it and eventually found the correct part for my toilet, which was just a touch longer, and now everything works perfectly. Just a heads up to double check measurements, because even toilets from the same model line may require different flapper lengths depending on the year or configuration. Bottom line: confirm compatibility by dimensions, not just model numbers, to save yourself the frustration.
