3" Premium Universal Flapper Install by Korky - korky.com/parts/flapper-seal-replacements/3-premium-universal-flapper
Hello and Welcome to Korky toilet repair. Today we are going to install your new Korky 3 Inch Universal Flapper. The first step is to shut off the water supply to your toilet. Next flush your toilet.
Several popular toilet models are printed on the back of the packaging. If your toilet model number appears on the card, adjust the white band to align the arrow with the number on the cone that is listed on the packaging. The toilet brand can usually be found between the toilet seat and the tank. Toilet model numbers are often stamped on the inside back wall of the tank.
If your toilet model is listed and you have adjusted the band to the correct setting, you will not need to adjust the flapper further.
If your toilet model is not listed, mark the water level in the tank with a pencil and drain the excess water. Remove the old flapper and install the Korky 3 Inch Universal Flapper by attaching the flapper ears to the tabs on the flush valve. If you have a two piece Kohler toilet with a 3” flapper, rotate the legs to fit the flush valve.
For some Mansfield toilets made after 2008, one flush valve peg may be larger than the other. Remove the red arm that is attached to that peg and install the black arm, by sliding it over the rubber post and pulling it tight. Then attach the flapper chain to the flush lever with minimal slack. Turn the water supply on and let the tank refill completely. Now turn the water supply off and flush
If the water level drops within a half inch of the pencil mark, your installation in complete. If the water level drops below the pencil mark, adjust the arrow on the white band to the next lowest number. If the water level is above the pencil mark, adjust the white band to the next highest number. Turn your water supply on and let the tank fill completely. Now turn your water supply off and flush. If the water level still drops below the pencil mark, adjust the arrow on the white band to the next lowest number. If the water level is still above the pencil mark, adjust the white band to the next highest number. Turn the water supply on and let the tank refill completely. Turn your water supply off and flush. Repeat this process until the water level drops within a half inch of the pencil mark. Your installation is now complete.
Congratulations, you have just installed your Korky 3 Inch Universal Flapper.
Thank you for choosing Korky.
