How to Replace a Refill Valve (pg. 3)

Attach the angle adapter to one end of the refill tube and attach the other end of the refill tube to the nipple on the top of the valve located just below the cap. Clip the angle adapter to the top edge of the overflow pipe. Cut the refill tube to size if necessary. Never insert the tube inside the overflow pipe. With the tube down inside the overflow pipe, it's possible to start a non-stop siphoning of water out of the tank.

Reattach the flush valve chain or strap to the trip handle. The chain should be long enough to just have a little bit of slack. Too short and the flush valve won't close; too long and the trip lever will hit the lid of the tank and the flush valve won't stay open long enough to flush the toilet.

If you have a problem with a chain getting caught under the flapper when it closes, try slipping a short length of a plastic straw over the chain. The straw will stiffen the chain and keep it from getting stuck under the flapper.

Finally, you have to open the top of the refill valve and flush it out. Unscrew the cap by lifting arm and rotating top 1/8 a turn counterclockwise. Hold a cup over the top while you turn the water supply on and off a few times to clear the line of sand and silt. Turn the water off and replace the cap. Make sure it is fully turned into the locked position before turning the water back on. Photo: Flushing out refill valve

The last step is to adjust the water level which is controlled by thesetting for the float cup. The water level should be at least 1/2-inch below the top of the overflow pipe. You'll see a small stainless steel clip on a slender vertical rod attached to the side of the valve. Squeezing the clip and sliding it up the rod will raise the water level; sliding it down will lower it. IMPORTANT: the water level must be kept at least a 1/2-inch below the top of the overflow.

Note: I have attempted to make the instructions for installing a new refill valve as generic as possible. But there are different adjustments that must be made for each type of valve, and you need to read all of the instructions that come with whatever refill valve you purchase.
