Pump Installation
Mount the pump
NOTICE Be careful to avoid cross-threading; use only
PTFE pipe thread sealant tape or PTFE-based pipe
thread compound when connecting threaded fittings to
PVC adapters.
1. Place the sink in its final location.
2. Remove any existing drain fittings back to the tail
piece (Figure 1). Make sure the existing tail piece
does not leak.
NOTICE: If the sink-drain tail piece is not 1-1/2”
NPT, you will have to adapt it (bushings, reducers,
etc.). In this case, wrap all joints with PTFE tape
before making connections.
3. Glue the 1-1/2” PVC pipe into the female adapter
(purchase separately).
Risk of fire or explosion . Be sure to follow
the cement manufacturer’s instructions when using
PVC cement. Do not use near fire or open flame.
4. Wrap the threads of the tail piece with 1 to
1-1/2 turns of PTFE tape. Thread the 1-1/2” NPT
female adapter onto the sink-drain tail piece. Thread
it hand tight plus 1/2 turn with a pipe wrench or slip
joint pliers. DO NOT overtighten.
5. Wrap the threads of the 1-1/2” male adapter
with 1 to 1-1/2 turns of PTFE tape and install
it in the pump inlet. Tighten it hand tight plus
1/2 turn with a pipe wrench or slip joint pliers.
DO NOT overtighten!
6. Measure the 1-1/2” PVC pipe 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. Swing the pump until it accurately
faces the discharge piping, and then mark the pump
and the inlet pipe/adapter assembly so that you
can accurately install the pump in Step 8. Arrange
a temporary support under the pump to relieve the
strain on the sink drain piping 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
into the male adapter (on the pump).
• Don’t allow any glue to get on the pump or in
the motor;
• Make sure the pump is facing the correct
direction (match the marks from Step 7);
• Put the support in place under the motor.
9. Wrap the 1-1/4” galvanized nipple with 1-1/2 to
2 turns of PTFE tape on each end and thread it into
the pump discharge port.
NOTICE: 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” 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 1-1/4”
male adapters with 1-1/2 to 2 turns of PTFE tape.
Thread one of the adapters into the other half of the
1-1/4” union, hand tight plus 1/2 turn with a wrench
or a pair of slip-joint pliers. DO NOT overtighten!
12. Install the discharge piping as shown in Figures 1
and 2. The order is:
1-1/4” PVC Pipe cut to fit,
90° Socket to Socket elbow,
1-/14” PVC Pipe cut to fit,
Male adapter,
Flow Control/Ball Valve,
Check Valve,
(NOTICE: 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.)
1-1/4” Outlet Pipe.
13. Connect the discharge piping to the building drain.
