BBU INSTALLATION INSTRUCTIONS
Risk of electrical shock. At the circuit breaker
or fuse box, turn off the electrical power to the sump
pump before beginning this installation.
Setup
1. Locate the high water level in your sump pit (that is,
the water level at which the existing (primary) sump
pump starts - see Figure 1). 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:
A) P : Unplug the pump and switch
IGGYBACK 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
B) N
O PIGGYBACK SWITCH
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.
C) A : When the pit has drained, turn
LL INSTALLATIONS
off (open) the circuit breaker or remove the fuse
again to avoid electrical shock while working on
the installation.
3. Support the discharge pipe so that it can't collapse
when you take it apart or cut it.
4. If your discharge pipe has a hose coupling, discon-
nect the coupling. If not, cut the vertical discharge
pipe at any convenient spot above the floor level.
5. Lift the pump and attached pipe out of the sump pit.

Installation
1. Study Figure 2 for suggested layouts.
The Easy-Install layout works better for deeper
sumps and allows a smaller diameter sump (diameter
13-1/2" or larger, depth more than 22").
The Alternate layout works better for wider, shal-
lower sump pits (diameter 18" or larger, depth 18-
22"). The Alternate layout will require that you
purchase (2) 1-1/4" x 90° elbows and (2) 1-1/4" x
close pipe nipples.
Other layouts may require more pipe fittings.
2. Find the high water level mark you made on the
discharge pipe in "Setup, Step 1". Cut the pipe at this
point and set the cut-off piece aside for use later.
Clean up and debur the cut ends.
3. Wrap the threads of the Battery Back Up pump (BBU
pump) and the 1-1/4" x close nipple with 1-1/2 – 2
turns of teflon tape (see Figure 2). Leave the first
thread free of tape and wrap clockwise (
4. Thread the tee, the close nipple, the 1-1/4" x 1-1/4"
check valve, and the BBU pump together. To get
them tight, hold the pump and insert a large screw-
driver down through the tee and tighten the whole
assembly with the screwdriver. D
When the assembly is tight, the pump and tee should
align vertically (no twist – see Figure 2).
5. Glue the cut-off piece of pipe (which you set aside
in Step 2) into the top of the tee.
NOTE: If your discharge pipe is 1-1/4" inch, glue one
of the reducer bushings supplied with the system into
the tee, then glue the pipe into the bushing.
6. Look at your primary pump to determine if you have
a check valve in or near the pump discharge. If not,
install the auxiliary check valve in the bottom arm of
the tee and install the slip coupling on the check
valve (see Figure 2). For 1-1/4" discharge pipe, glue
the remaining reducer bushing into the slip coupling.
NOTE: If the primary pump assembly already
includes a functioning check valve, do not use the
auxiliary check valve included in the BBU system.
You need one check valve between the primary
pump and the tee (to prevent backflow from either
pump into the sump pit), but two check valves will
restrict the pipe too much.
7. Trial Fit ( ): Place the primary pump
NO GLUE YET
assembly back in the sump pit and add (dry) the
tee/check valve/BBU pump assembly to it. If neces-
sary, also include the 1-1/2 x 1-1/4 reducer bushing
and the slip coupling and auxiliary check valve (see
"NOTE", above).
8. Measure the assembly against the hanging upper
discharge pipe (where you cut it in Step 1 under
"Setup"). Mark the discharge pipe coming up from
the tee 1/4" below the point of overlap (that is, you
should have an air gap of 1/4" after you cut the
pipe). Don't cut anything yet.
