    To prepare the valve you will need to put the rubber washer onto the fill valve. Adjust the height of the fill valve as necessary.

    Tip: You want the fill valve to be slightly taller than the overflow tube but not so tall that it will prevent the tank lid from closing.

    Set the fill valve into the toilet tank. Make sure the nipple is facing the overflow tube. Tighten the nut under the toilet tank by hand until firm. Then use pliers to tighten just a little more.

    Reconnect the water supply line to the fill valve. Once again you can hand tighten first and then use pliers to tighten a little more.

    Install the fill tube clip onto the overflow tube. Cut the rubber hose to length and connect it to the fill tube clip. Turn the water back on and check for leaks under the toilet tank.

    Adjust the water level appropriately for your toilet. The tank should fill to a marked water line.
