Does your toilet flush twice? This happens when your flapper floats too long and flushes too much water. If you do not have an adjustable flapper, you need to get one. Adjustable flappers let you control how long the flapper floats and ultimately how much water goes into the bowl. To fix this all you have to do is adjust your flapper’s settings, so the flapper closes faster and flushes less water. We recommend getting a Korky 2X Long Life flapper – they’re made of a 2x stronger material that resist chemicals.
