Installation (continued)
22. Your local or state plumbing code may require you to test the system with a“10 ft. water column test”. If so, make certain the pump
chamber lid screws are tightened down properly and that the lid gasket is seated. Plug the 4 in. diameter toilet opening (in the top of the
tank) with an expandable plumber's plug (available at hardware stores). Also plug any other openings in the system except the highest
one(normally the top of the vent stack). Make sure that if the system is tied in to existing vents, drains, sewers, toilets, etc., that any
openings in these system components are also plugged securely. The system can now be tested per code requirements. Consult your
local code officials for more information about this test.
CAUTION: Risk of flooding. Risk of damage to floor and possible flooding. The tank and lid will expand with the water column pressure
while being tested. If you are installing the tank under the floor, complete the testing before the floor is installed.
23. Install the long studs and nuts (Repair Parts, Key No. 10) that are used to fasten the toilet to the tank or subfloor.
NOTE: To tighten the studs, thread both nuts onto one stud, then use the 1/2 in. wrench to tighten the upper nut. The nuts should jam on
the stud and turn it into the threaded hole in the tank. Remove the nuts and repeat for the second stud.
NOTE: A standard floor flange is not required. The position of the toilet must be determined to allow the stud to be inserted in the correct
holes. Install the wax ring. Be sure to align the studs for installation of the toilet bowl in the desired direction. (i.e., If the vent and discharge
pipe are to be installed behind the wall to one side of the upflush system, you can turn the toilet sideways on the tank top so that the flush
tank is flat against the wall – see Figure 5).

24. Install the wax toilet bowl seal(s) at the hole on top of the tank and install the toilet following the instructions from the wax seal
package.
NOTE: Do not use a wax seal having a flange that extends into the tank; it may cause clogging. If a 1/2 in. or 1/4 in. floor is installed over the
tank, the appropriate floor flange extender seal kit must be used. See NOTICE: Floor Seal. Hook up the water line to the toilet. Turn on the
water and fill the toilet tank. Test for leaks, flush the toilet, and allow the pump to cycle to ensure proper operation.
