How to Install QuietFILL Platinum Toilet Fill Valve by Korky - 528MP https://www.korky.com/parts/fill-valve-replacements/quietfill-platinum-fill-valve Hello and welcome to Korky Toilet Repair, today we will be teaching you how to install your new Korky QuietFILL Platinum Fill Valve. The first step is to shut off the water supply to your toilet. Then flush and hold the lever down to drain the water from your tank. Sponge out the remaining water from your toilet tank. Place a bucket under you toilet tank to catch any excess water. Disconnect the water supply line and remove the mounting nut. Remove the old fill valve. Now, turn the top of your new fill valve counterclockwise 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. Remove the fill valve. Lock the fill valve in place by twisting the upper half clockwise. Make sure the ribs line up with the pegs. Attach the refill tube to your new fill valve. Make sure the refill tube has a direct path to the flush valve. Insert the metal clip into the refill tube and then attach the clip to the flush valve. Turn the refill adjuster clockwise to the fully open position. Reattach the water supply line and turn the water supply on. Wait 2 minutes for the water in the bowl to settle. Mark the water level in the bowl with a pencil or dry erase marker, then flush. If the bowl water level reaches the mark before the tank is finished filling, 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.
