INSTALLATION
NOTE:
Install the battery backup system when the primary sump pump isn’t needed. Read the instructions and prepare all
supplies before starting.
If your check valve is a rubber check valve, you need a 1 1/4” (3.2 cm) nipple, a 1 1/4” (3.2 cm) FPT x 1 1/4” (3.2 cm)
slip adaptor, and a piece of 1 1/4” (3.2 cm) PVC pipe to connect with the rubber check valve.
• Verify that the existing primary sump pump is
in good working order. If the primary pump is
questionable, replace with the same or a higher HP
pump. It is better for the primary pump to have a
vertical float switch or electrical switch. A tethered
float switch takes more sump pit space and might
interfere with the backup DC pump.
• Manually operate your primary sump pump and
pump out the water in your sump pit. Do not let the
pump run dry. This will damage the pump.
• Disconnect the primary sump pump power source
before attempting to install. Never handle a pump
with wet hands or when standing on wet or damp
surface or in water. Fatal electrical shock could
occur.
• Remove any silt or accumulated debris from the sump pit and surrounding area.
Battery backup pump installation
There are two ways to install the battery backup pumps. If the sump pit base is bigger than
18” (46 cm) in diameter, enough space exists to install both primary pump and the DC pump and
the DC pump can be installed on the same base as the primary pump or a little bit higher than the
primary pump. Otherwise, install the DC pump above the primary sump pump.
To install:
1. Remove the hose coupling or cut the main discharge pipe.
2. Separate the primary sump pump from the discharge pipe.
3. Lift the primary sump pump and the attached discharge pipe out of the sump pit.
4. Wrap the thread of the discharge of the DC pump with non-stick tape. Thread a 90°,
1 1/4” (3.2 cm) FPT elbow onto the discharge of the DC pump.
5. Wrap the thread of the check valve with non-stick tape and thread the check valve onto the 90°
elbow.
6. Install a check valve onto the primary pump discharge pipe. Install the rubber hoses onto the
check valves.
7. Try to assemble the system (no glue). Insert a piece of PVC pipe into the tee and insert another
piece of PVC pipe into the 1 1/4” (3.2 cm) adaptor. Plug the rubber hose onto the PVC pipe.
Connect the tee to the primary sump and verify the assembly in the sump pit. If necessary, adjust
the PVC pipe length in the rubber hose so that nothing interferes with the primary pump and
switches.
8. Recheck the alignment and glue all the joints.
9. After the glue has set, slide the hose clamps onto the rubber hose and tighten the clamps.
