READ AND FOLLOW
SAFETY INSTRUCTIONS!
This is the safety alert symbol. When you see this
symbol on your pump or in this manual, look for
one of the following signal words and be alert to the
potential for personal injury!
DANGER warns about hazards that will
cause serious personal injury, death or major property
damage if ignored.
WARNING warns about hazards that can
cause serious personal injury, death or major property
damage if ignored.
CAUTION warns about hazards that will or
can cause minor personal injury or property damage if
ignored.
The word NOTICE indicates special instructions which
are important but not related to hazards.
1. To avoid risk of serious bodily injury due to electrical
shock or burns and property damage due to flooding,
read the safety instructions carefully before installing
pump.
Battery acid is corrosive. Do not spill on
skin, clothing, or battery charger. Wear eye and head
protection when working with battery. Connect and disconnect DC output terminals only after removing the
charger from the AC outlet. Never allow the DC terminals to touch each other.
Hazardous Voltage. Can cause severe or
fatal electrical shock. Do not plug in or unplug battery
charger while standing on a wet floor or in water. Be
sure one hand is free when plugging in or unplugging
charger. If basement floor is wet, disconnect power to
basement before walking on floor.
Risk of flooding. Do not run pump dry. To
do so will damage seals and can cause leaking and property damage.
2. Follow local and/or national plumbing and electrical
codes when installing the system. A ground fault circuit interrupter (GFCI) is recommended for use on
any electrical appliance submerged in water.
3. Use this system only for backup sump pump duty in
a residential application. It is not designed as a primary sump pump.
4. Do not lift pump by electrical cord.
Risk of electrical shock. Do not lift the
pump by the electrical cord; lift pump only by the discharge pipe, lifting ring or handle on the pump. Lifting
by the cord can damage the cord.
5. Pump clear water only with this pump.
6. Pump is permanently lubricated at the factory. Do
not try to lubricate it!
7. Keep battery charger and battery box off of the floor
and in a dry, cool, well ventilated area.
NOTICE: If a Carbon Monoxide (CO) sensor is
installed, it must be at least 15 feet away from battery charger in order to avoid nuisance CO alarms.
Please refer to your CO detector’s installation guidelines for more information.
8. To avoid danger of fire or explosion, keep sparks and
flame (pilot light) away from battery.
9. Maximum vertical pumping distance is 16 feet
(4.9M) for Model DB10018T-01 and 18 feet (5.5M)
for Model DB20018T.
10. Make sure sump is clear of debris. Debris can damage the pump which can result in flooding.
GENERAL INFORMATION
The battery back-up sump system is not a substitute for
your primary sump pump. It is designed to temporarily
back up your primary sump pump during a power outage or other problem which prevents normal operation
of the primary pump. Do not use this system to pump
flammable liquids or chemicals. Pump clear water only
with this pump.
Keep battery charger dry and protected from damage.
In an emergency (such as an extended power outage)
which depletes the system deep cycle battery, your automobile battery may be temporarily substituted. Be sure to
replace the system deep cycle battery as soon as possible. Use of an automobile battery instead of a 27M or
24M deep cycle battery in this system will significantly
reduce system total performance. Automobile batteries
are not designed for this type of application and will be
quickly ruined by the repeated charge/discharge cycling.
Do not use GEL-type batteries or maintenance-free
(sealed) batteries with this charger. GEL-type batteries
require a lower voltage than the charger is designed for;
they may overcharge. Maintenance-free (sealed) batteries
require a higher voltage and may never reach full charge.
NOTICE: This unit is not designed for applications involving salt water or brine! Use with salt water or brine will
void warranty.

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 discharge 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.

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 recommended depth of the basin is 22”.

2. Wrap the threads of the close nipple (Key No. 3 on
Page 12) counterclockwise with 2 turns of Teflon
TM
tape and set aside.
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.
3. The backup pump (Key No. 6) and check valve
assembly (Key Nos. 4 and 5) come preassembled.
Thread the close pipe nipple into the check valve.
4. To thread the tee (Key No. 2B - also included reducer bushings) into the close nipple:
Hold the check valve assembly with the channel
locks, insert the screwdriver into the tee for leverage,
and tighten the tee with the screwdriver. Finish with
the tee in a straight up and down (vertical) position.
5. Clean the pipe ends with the cloth towel.
6. Glue the cut-off piece of discharge pipe into the top
of the tee.
NOTICE: If your pipe is 1-1/4”, you will need to glue
the reducer bushings into the tee and glue the pipe
into the bushing. Place the assembly onto the primary discharge pipe. Do not glue the tee onto the primary pump discharge pipe.
7. Mount the back-up pump float switch assembly (Key
No. 7) loosely to the discharge pipe with the cable ties
(Key Nos. 7A & 7B). See Figure 6, on Page 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.
Cut the Discharge Pipe:
1. Put the double pump assembly into the sump pit.
NOTICE: The discharge pipe now overlaps the dis-
charge pipe that leads outside.
2. Mark the discharge pipe where it should be cut. Be
sure to leave a 1/4” air gap between the ends of the
pipes. This gap will absorb the noise from vibration
and allow for flexibility.
3. Make the third cut. See Figure 8.
TRIAL ASSEMBLY OF DOUBLE PUMP
ASSEMBLY IN THE SUMP PIT:
1. Connect the discharge pipe to the exterior discharge
pipe with the rubber coupling and clamp kit (Key
No. 1). Do not tighten the clamps until all the final
adjustments are complete.
2. Make the final adjustments. Make sure the pumps
and the switches do not interfere with each other.
Make sure there is plenty of room for the float
switches to either swing or to move up and down
from their “off” to their “on” positions.
Mark and Glue Assembly:
1. Mark the pipe and the fittings at all the connections
with a pencil. These marks will be used as a reassembly guide while gluing to be sure everything is still in
the right place and nothing has moved.
2. Loosen the rubber coupling and clamp connection.
3. Carefully pull the double pump assembly back out of
the pit.
4. Take the tee assembly off of the primary discharge
pipe. Do Not unscrew any of the TeflonTMtaped pipe
nipple connections.
5. Clean all the PVC pipe ends with the PVC cleaner.
Hazardous fumes. Follow the cement
and cleaner manufacturers instructions. Use the PVC
cement in a well ventilated area away from fire or
flames.
6. Glue the PVC fittings where indicated by the pencil
marks. Wait 10 minutes for the glue to cure.
Final Assembly:
1. Put the double pump assembly back into the pit.
2. Install and tighten the rubber coupling and clamp kit.
3. Make the final float switch adjustments and tighten
the cable ties.
