Today I will be your personal guide in showing you how to install the Korky QuietFILL toilet Fill Valve and Premium Flapper. The first step is to shut off your water supply to your toilet by turning the valve clockwise. Flush your toilet to get rid of excess water in the toilet. Next, sponge out the remaining water in the toilet tank. Place a bucket or pail under the toilet tank to catch the excess water from the supply line and toilet tank. Disconnect the water supply line and unscrew the mounting nut. Pull up on the old valve and lift out of the toilet tank. Remove the old flapper from your flush valve. For plastic flush valves, take your new Korky Flapper and cut off the collar. Attach the flapper ears to the tabs on the flush valve. Then attach the flapper chain to the flush lever with minimal slack. Pull out the valve, place into your toilet tank. To adjust the height, push down until the fill valve water line and tank water line match. Remove toilet fill valve, lock the fill valve in place by simply twisting the upper half clockwise. As a double check, make sure the grooves match up the pegs. Place the Korky Quietfill toilet Fill Valve into your toilet tank and hand tighten the mounting nut. Insert the metal clip on one end of the refill tube and attach onto the overflow tube. Then install the opposite end to the fill valve. If kinking occurs, simply cut the refill tube with a scissors to shorten the overall length. Reconnect the water supply line. Then turn on the water supply line by turning the valve counter clockwise until fully open. If you need further assistance with the installation, visit our website or contact us at 1-800-LAVELLE.
