Installation
5
Method A
The recommended method suggests installing both of the
pumps on the floor of the sump pit. See Figure 2. The min-
imum 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” 90°
elbows and 2 1-1/4” close pipe nipples.
1. Make the second cut in the discharge pipe at the
pencil mark as shown in Figure 1 on Page 4, and in
Figure 2, 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 11) from the battery back-up pump (Key No. 5)
discharge and set it aside. See Figure 3. 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 3.
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 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
recirculation into the Primary Pump when the
Backup Sump Pump comes on.
11. Slip a reducer bushing onto the end of the pipe com-
ing 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.
