Frequently Asked Questions

Q. "I have the original flush valve part #738069-0070A, but your diagram shows it has been replaced with part #738109-0070A. These two flush valves do not look anything alike. How is the replacement #738109-0070A properly installed?"
A. The replacement part #738109-0070A is a compression style flush valve held in place when pressure is applied to the compression washer forcing it against the inside of the tank cavity. To install this #738109-0070A, use the flat disc (installation driver) included with the flush valve and place it inside the flush valve so the slots on the disc line up with the vertical ridges on the plastic insert inside the flush valve. Use a large screwdriver or a 3/8" socket extension and turn the disc counterclockwise to loosen the compression washer to the smallest diameter in order to place the flush valve into the hole in the bottom of the tank. Rotate the flush valve as needed to keep the fill valve rod or tank lever out of the way of the overflow tube. Now turn the flat disc clockwise to begin tightening the flush valve. As the flush valve is tightened the washer will begin to compress evenly on the inside of the tank hole. The flush valve may want to rotate from your set position so you will have to hold the overflow tube with one hand as you are tigtening. Tighten until the flush valve is firmly in place. Remove the disc (installation driver) and install the flapper. Test for leaks.
