Installation
1. Make the second cut in the discharge pipe at the
pencil mark as shown in Figure 1 on page 4, and in
Figure 4, on Page 5. Clean the pipe ends with a
cloth towel and set the cut-off piece of discharge
pipe aside.
2. Remove the check valve assembly (Key No. 4 on
Page 15) from the battery back-up pump (Key No. 5)
discharge and set it aside. See Figure 5. The check
valve assembly will be used later, during assembly.
3. Thread a 90° elbow (purchased locally) onto the dis-
charge of the back-up pump.
4. Wrap the threads of all 3 of the close pipe nipples
(Key No. 3) with 2 turns of Teflon™ tape and thread
one of them into the elbow. Set the other 2 aside.
5. Thread the check valve assembly, removed back in
step 2, onto the close pipe nipple.
NOTICE: Make sure the check valve is installed in the
correct direction. See the inset drawing in Figure 5.
6. Thread a close pipe nipple into the other end of the
check valve.
7 Thread the second 90° elbow onto the pipe nipple.
8. Thread the last pipe nipple into the elbow.
9. Thread the tee onto the pipe nipple and set this
assembly aside.
10. Install a short length of pipe into the top of the check
valve in the primary pump discharge. See Figure 6.
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
recirculation into the Primary Pump when the
Backup Sump Pump comes on.

11. Slip a reducer bushing (Key No. 2A) 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.
12. Slip the tee and the back-up pump subassembly onto
the reducer bushing.
13. Glue the cut off piece of pipe into the top of the
reducer bushing in the top of the tee.
14. Mount the float switch assembly (Key No. 7) loosely
to the discharge pipe with the cable ties (Key Nos.
7A & 7B). See Figure 6. Approximately 2.5" (63.5
mm) of cord length should be left between the float
and the clamp. Do not tighten the cable ties.
Adjustments may be needed later.
15. Skip to the section "Cut the Discharge Pipe", Page 7.
Method B
Method B suggests installing the back-up pump above
the primary sump pump. See Figure 7. The minimum
required sump basin diameter for this type of installation
is 13.5" at the bottom of the pit, and the minimum rec-
ommended depth of the basin is 22".
1. Make a second cut in the discharge pipe at the pencil
mark made in step 1, on Page 4, and set the cut-off
piece of discharge pipe aside. See Figures 1 and 7.
