How to Install - Korky QuietFILL Platinum Fill Valve & Large 3” Flapper Kit https://www.korky.com/parts/fill-valve-replacements/quietfill-platinum-fill-valve-3-flapper-kit Hello and Welcome to Korky Toilet Repair. Today we are going to install your new Korky QuietFILL Platinum Fill Valve & Large 3” Flapper Kit. The first step is to shut off the water supply to your toilet. Next flush your toilet. Mark the water level in the tank with a pencil. Drain the excess water. Sponge out the remaining water in your toilet tank. Place a bucket underneath your toilet tank to catch any excess water. Disconnect your water supply line and remove the mounting nut. Remove the old fill valve. 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. Now, turn the top of your new fill valve counter clockwise and pull up to fully extend. Place the valve in the tank and press down on the fill valve until the corner of the silver cover lines up with the top of the flush valve. Lock the fill valve in place by twisting the upper half clockwise. Make sure the rib on the top of the valve lines up with the pegs on the bottom half. Attach the refill tube to your new fill valve. Make sure the refill tube has a direct path to the flush valve. When your fill valve is set, screw on the mounting nut until hand tight. Push the refill tube towards the front of the tank to ensure the port is locked in place. Insert the metal clip into the refill tube and attach the clip to the flush valve. Turn the refill adjustor clockwise to the fully open position. Reattach the water supply line. Turn the water supply on and wait for the tank to fill completely. Turn the water supply off and flush. If the water drops within a half inch of the pencil mark your flapper installation is finished. 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 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. Turn the water supply on and let the tank fill completely. Flush. Wait 2 minutes for the water in the bowl to settle, the excess water will drain out. Mark the water level in the bowl with a pencil or dry erase marker. Flush. If the bowl water level reaches the mark before the tank is finished filing, turn the dial counter-clockwise to reduce flow. If the bowl water level is below the mark once the tank is done filling, turn the dial clockwise to increase flow. Repeat this step until the water level reaches the pencil mark at the same time the tank finishes filling.
