What is a Toilet Flapper?
Before diving into the specifics of the Kohler 1.6 Gallon Toilet Flapper, it is essential to understand what a toilet flapper is and its function.

– Compatibility: As mentioned earlier, make sure you check if the flapper is compatible with your specific toilet brand and model.
– Size: Check the size of your current flapper and compare it with the dimensions of the new one to ensure a perfect fit.
