8. Slide the pump up into position and glue the pipe into the male adapter (on the pump).
•No glue on the pump or in the motor;
• Make sure the pump is facing the right direction (match the marks from Step 7);
• Put the support in place under the motor.
9. Wrap the 1-1/4 in. galvanized nipple 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. Over-tightening can crack the plastic.
10. Hold the nipple with a pipe wrench and thread one half of the 1-1/4 in. union onto it, hand tight plus 1-1/2 turns
with a pipe wrench or slip-joint pliers.
11. At this time, wrap the threads on both the 1-1/4in. male adapters 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 in. union, hand tight plus 1/2 turn with a
wrench or a pair of slip-joint pliers. DO NOT over tighten!
12. Install the discharge piping as shown in Figures 1 and 2. The order is:
a. 1-1/4 in. PVC Pipe cut to fit
b. 90° Soc. to Soc. elbow
c. 1-/14 in. PVC Pipe cut to fit
d. Male adapter
e. Flow Control/Ball Valve, Check Valve
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 in. Outlet Pipe
13.Connect the discharge piping to the building drain.
OPERATION
Plug in the Pump
AFTER the pump is completely installed, plug the switch into a GFCI protected, properly grounded outlet. Plug the
pump into the back of the switch’s plug.
Adjusting the Flow
The drain pump can pump up to 21 gallons per minute (GPM). Normal sink drains allow only 5 to 6 GPM to flow.
Adjust the discharge shut-off/flow balancing valve as follows so that the pump does not cycle on and off when the
faucets are on full.
 Run water into the sink. The pump will start when it detects water.
 Check for leaks. If leaks are found, unplug the pump power cord and fix the leaks before proceeding.
 Put a stopper in the drain and allow the sink to fill up a few inches.
 Open the discharge shut-off valve, open the faucets, and remove the stopper to drain the sink.
 The pump will start. Adjust the discharge shut-off/flow balancing valve until the pump runs continuously while
the faucets are running and the sink is draining. If the water level rises with the pump on, slightly open the
discharge valve to balance the flow. If it drops, slightly close the discharge valve.
