NOTE: The vertical height from the check valve to the pipe outlet should be at least 6' to void check valve leakage.
The check valve and ball valve must be below the sink line.
5.
Wrap the threads of the 1-1/2" male adapter (Part No.3) with 1 to 1-1/2 turns of PTFE pipe thread sealant tape and
install it in the pump inlet. Hand tighten it plus another 1/2 of a turn with a pipe wrench or slip joint pliers. DO NOT
OVERTIGHTEN.
6.
Measure the 1-1/2" PVC pipe (Part No.2) against the drain and the pump and trim the pipe to fit.
7.
Do a trial assembly (dry - no glue) of the pump onto the drain pipe. Adjust the pump until it faces the discharge
piping. Mark the pump and the inlet pipe/adapter assembly so you know where to place the pump later on. Create a
temporary support under the pump while the glue is setting. Leave it in place while you measure and cut the
discharge piping (Step 12).
8.
Slide the pump up into position and glue the pipe (Part No.2) into the male adapter (Part No.3 on the pump).
* Do not get any glue on the pump or in the motor.
* Confirm the pump is facing the correct direction.
* Place support under the motor.
9.
Wrap the 1-1/4" galvanized nipple (Part No.4) with 1-1/2 to 2 turns of PTFE pipe thread sealant tape on each end
and thread it into the pump discharge port.
NOTE: Tighten this only enough to prevent leaking. Overtightening can crack the plastic.
10. Hold the nipple (Part No.4) with a pipe wrench and thread one half of the 1-1/4" union (Part No.5) onto it, hand
tighten plus 1-1/2 turns with a pipe wrench or slip-joint pliers.
11. Wrap the threads on both the 1-1/4" male adapters (Part No.6) with 1-1/2 to 2 turns of PTFE pipe thread sealant
tape. Thread one of the adapters into the other half of the 1-1/4" union (Part No.5). Hand tighten plus 1/2 turn with a
wrench of a pair of slip-joint pliers. DO NOT OVERTIGHTEN.
12. Install the discharge piping as shown in Figures 1 and 2. The order is:
a. 1-1/4" PVC Pipe cut to fit (Part No.7)
b. 90° Soc. to Soc. Elbow (Part No.8)
c. 1-/14" PVC Pipe cut to fit (Part No.7)
d. Male adapter (Part No.6)
e. Flow Control/Ball Valve (C), Check Valve (B)
NOTE: Install the check valve in the vertical discharge pipe with the threads down. Be sure the flow arrow points
AWAY from the pump. That is, when the check valve is correctly installed, the arrow showing direction of flow
should point UP.
f. 1-1/4" Discharge Pipe (Part No.9)
13. Connect the discharge piping to the building drain.
