INSTALLATION
INSTALLATION (TYPICAL): COMMON DISCHARGE
Unplug the primary sump pump before beginning this
procedure.
burn, or kill.
1. Locate the high water level in your sump pit (the water
level at which the existing (primary) sump pump starts -
see Figure 1). Turn off power to pump and mark this point
on the discharge pipe with a pencil or marker.
2. Drain the sump pit as far as possible without running the
pump dry. Do this by:
Piggyback switch: Unplug the pump and switch from

the outlet, then unplug the pump from the piggyback
switch. Reset the circuit breaker or reinstall the fuse
and plug the pump directly into the outlet. The pump
will start. Drain the pit and unplug the pump. OR
No piggyback switch: Reset the circuit breaker or

reinstall the fuse and use a non-conducting broom
handle or stick to raise the float switch; the pump
should start. Drain the pit and then release the switch.
EASY INSTALL – METHOD A
The recommended Easy Install method suggests installing
both of the pumps on the floor of the sump pit. See Figure 2.
The minimum required sump basin diameter at the bottom of
the pit and the recommended depth of the sump basin is 18".
Some additional materials you will need are (2) 1-1/4" NPT 90°
elbows and (2) 1-1/4" NPT close pipe nipples.
1. Make the second cut in the discharge pipe at the pencil
mark as shown in Figure 1. Clean the pipe ends with a cloth
towel and set the cut-off piece of discharge pipe aside.
2. Thread a 1-1/4" NPT 90° elbow (purchased locally) onto the
discharge of the back-up pump.
3. Wrap the threads of all 3 of the close pipe nipples with 2
turns of PTFE pipe thread sealant tape and thread one of
them into the elbow. Set the other 2 aside.
4. Thread the check valve assembly onto the close pipe
nipple.
NOTE: Make sure the check valve is installed in the correct
direction. See the inset drawing in Figure 3.
5. Thread a close pipe nipple into the other end of the check
valve.
6. Thread the second 1-1/4" NPT 90° elbow onto the pipe
nipple.
7. Thread the last pipe nipple into the elbow.
8. Thread the tee onto the pipe nipple and set this assembly
aside.
9. Install a short length of pipe into the top of the check valve
in the primary pump discharge. See Figure 4.

Risk of electrical shock. Can shock,
NOTE: There must be a check valve installed in the
Primary Sump Pump discharge pipe between the tee and
the Primary Sump Pump. This will prevent recirculation
into the Primary Pump when the Backup Sump Pump
comes on.

10. Slip a reducer bushing (if required) onto the end of the pipe
coming from the primary pump discharge. Do not glue this
connection yet.
NOTE: If your discharge pipe diameter is 1-1/4", you will
need to glue the reducer bushings into the tee first and
then slip the cut off piece of discharge pipe into the
bushing.
11. Slip the tee and the back-up pump subassembly onto the
reducer bushing.
12. Glue the cut off piece of pipe into the top of the reducer
bushing in the top of the tee.
13. Mount the float switch assembly loosely to the discharge
pipe with the cable ties. See Figure 4. Do not tighten the
cable ties. Adjustments may be needed later.
