Installation
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.
NOTICE: 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.
NOTICE: 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 recir-
culation 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.
NOTICE: 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.
