Before installation, read the following instructions carefully. Each Liberty Pump is individually factory tested to ensure proper
performance. Closely following these instructions will eliminate potential operating problems, assuring years of trouble-free service.
Health Risk. Sump water is non‐potable. To reduce the risk of contamination of the potable water supply additional backflow
protection must be provided by the installer to meet the requirements of the local plumbing code or the requirements of the local
water authority. As per the Uniform Plumbing Code and per the Plumbing Codes of some states, including the State of
Michigan, installation of this product requires the use of an RP (RPZ) backflow protection device. Contact your local plumbing or
water authority for more information regarding the requirements for your specific area.
Risk of electric shock. When installing the SumpJet®, Always disconnect any electric pumps from the power source before
handling or making adjustments.
The SumpJet® is designed for use with municipal water supply, and is intended to be used as an emergency backup to
your existing pump system.
The SumpJet® comes with a foot valve installed and therefore does not require a check valve on the discharge. The foot valve
has a removable poppet. Where freezing discharge pipes are a problem, simply unscrew the strainer screen, remove the
poppet and spring, and replace the strainer. The SumpJet® will now allow water to flow back into the pit, eliminating discharge
pipe freezing.
Maximum water pressure = 100 psi (690 kPa) with the valve closed.
Minimum water pressure = 30 psi (207 kPa) with the valve open. (less pressure may not eject water from your basement)
For nominal backflow protection SumpJet® is pre-equipped with an internal check valve certified to ASME A112.18.3-2002 and
ASME A112.18.1/CSA B125.1.2005.
The discharge of the water-powered sump pump must not to be connected to the primary sump pump. Also, the discharge of
the water-powered sump pump is not to be directly connected to the municipal drain. An air gap with a minimum 1” gap should
be used, or the discharge should be directed outside of the building, with the end of the pipe between 150 and 610 mm (6 and
24 in) above the ground or the flood level of the area receiving the discharge.
The inlet of the SumpJet® is pre-equipped with a push-type pipe connector, SharkBite®, and can be used with PEX, CPVC, or
copper pipe.
Do not use pipe dope on inlet threads, and do not sweat copper fittings within 18” of SumpJet® body. Use PTFE (Teflon®)
sealing tape only when assembling threaded fittings into SumpJet® inlet. Do not over tighten threaded inlet fitting, and do not
hold onto float plunger shroud when tightening.
Purge water line prior to connection to SumpJet® to insure debris does not enter unit and clog the operating valve.
The SumpJet® utilizes a quick acting valve which, per UPC, requires the use of an approved water pressure absorbing device
to prevent water hammer.
DO NOT use SumpJet® in hot water.
The SumpJet® is designed for use in clear water only. It is not designed to remove waste water, sewage, effluent, or water with
debris in it.

2-1 INTRODUCTION
This manual was prepared to assist you in the correct installation, operation, and maintenance of your Liberty Pumps
SumpJet®. Please read it completely before installing the pump. Make certain that you are familiar with the contents, and the
chapters on installation and operation are fully understood before running the pump.
Liberty products are designed for minimal maintenance. However, regular checks will ensure longer life and greater operating
reliability.
WARRANTY: No repair work should be carried out during the warranty period without prior factory approval. To do so may
render the warranty void.
SERIAL #: In all correspondence and reports, make certain that the pump serial number is given.
2-2 DESIGN OF PUMP
The Liberty SumpJet® is designed for emergency backup to your existing pump system. It uses the municipal water supply to
evacuate water from the sump. It is not intended to be used as the main sump water removal pump. It is intended to remove
clear sump water only. Liberty Pumps recommends the use of an audible high water alarm. The model SJ10A features an
alarm system to warn when the SumpJet® is activated. If you purchased the model SJ10 (without alarm) and wish to add the
alarm feature, order part number ALM-P1 from you local distributor or contact the factory for more information. Prolonged use of
the SumpJet® will result in increased municipal water consumption. The SumpJet® will use approximately 1 gallon of water
to remove 2 gallons of sump water, depending on elevation.
2-3 INSPECTION UPON RECEIPT
The shipping container should be immediately inspected for damage that may have occurred in shipment. Exercise care in
opening the shipping container to avoid damage to the pump. Remove any blocking and cushioning from within the container.
Check all cushioning for spare parts before discarding. Visually check the pump and any spare parts for damage. Report any
damage or shortage of parts.
2-4 STORAGE BEFORE USE
Liberty pumps are shipped from the factory ready for installation and use. They should be held in storage if the pump station is
not complete. If storage is necessary, the pump should remain in its shipping container. It should be stored in a warehouse or
storage shed that has a clean, dry temperature-stable area where the pump and its container should be covered to protect it
from water, dirt, dust, etc.
AT NO TIME SHOULD THE PUMP BE STORED WITHIN AN INCOMPLETE WET PIT. THE PUMP SHOULD
NOT BE PLACED INTO THE PIT UNTIL IT CAN BE FULLY OPERATED.
2-5 LONG TERM STORAGE
If it is necessary to store a pump for a long period of time, it should be stored indoors in a clean, dry temperature-stable
environment. The pump should be covered to protect it from dust, dirt and water.
Do not allow the pump to freeze.
2-6 MAINTENANCE
Installed pumps which are idle for long periods of time should be manually operated once a month to ensure proper
operation. Check for proper operation of the float and clean any debris that may be on the float or the suction screen. Make
sure that the float operates freely without any restrictions.
2-7 OPTIONAL ALARM
The SJ10A pump comes supplied with a pre-mounted alarm probe. If you would like to add an alarm to the SJ10 system,
Liberty Pumps offers a model, ALM-P1, which is suitable for this installation.

Figure 1 Typical installation
Note- The SumpJet® comes fully assembled. Only placement and connection is required.
3-1 For nominal backflow protection SumpJet®is pre-equipped with an internal check valve certified to ASME A112.18.3-2002 and
ASME A112.18.1/CSA B125.1.2005. Additional backflow protection must be provided by the installer to meet the requirements
of the local plumbing code or the requirements of the local water authority. As per the Uniform Plumbing Code and per the
Plumbing Codes of some states, including the State of Michigan, installation of this product requires the use of an RP (RPZ)
backflow protection device. Contact your local plumbing or water authority for more information regarding the requirements for
your specific area. The discharge of the water-powered sump pump must not to be connected to the primary sump pump. Also,
the discharge of the water-powered sump pump is not to be directly connected to the municipal drain. An air gap with a
minimum 1” gap should be used, or the discharge should be directed outside of the building, with the end of the pipe between
150 and 610 mm (6 and 24 in) above the ground or the flood level of the area receiving the discharge.
3-2
Disconnect the existing sump pump from the electrical supply before installation of the SumpJet®.
3-3 DO NOT USE A GARDEN HOSE. Garden hose is not designed to hold municipal pressure indefinitely. It could
leak or burst and cause flooding. The SumpJet® requires permanent piping methods such as copper, PEX, or CPVC, or any
other permanent plumbing method, be used for installation. To achieve maximum performance from the SumpJet® it is
recommended that the unit is plumbed with 3/4” pipe. All water supply piping shall be made of materials and methods approved
by the local plumbing codes.

3-4 The inlet of the SumpJet® is factory equipped with a SharkBite® push-type fitting. This fitting can be used with various
approved 3/4-inch potable water tubing and pipe, such as PEX tubing (ASTM F876, CSA B137.5), copper pipe (ASTM B 88), or
Copper Tube Size (CTS) CPVC pipe (ASTM D 2846, CSA B137.6). Follow the instructions below for connecting the municipal
water line to the SharkBite®. For more details on using the SharkBite® go to www.cashacme.com.
3-5 Using the Hose clamps provided, mount the SumpJet® to the
existing discharge pipe. Place the unit so that the float level will
operate a few inches above the turn on level of the existing sump
pump. (Refer to figure 2). Tighten hose clamps on discharge
pipe. NOTE: If this type of installation will not work refer to
alternate installation 3-17.
3-6 After mounting the SumpJet®, you are ready to hook into the
existing municipal water supply line. Shut off the municipal water
supply, and plumb the tubing or piping into the municipal water
supply line. Use the appropriate backflow prevention for your
jurisdiction. The water supply and discharge piping each require
a union or other quick‐disconnect fitting to make the pump
accessible for servicing, and a dedicated shut off valve installed
on the water supply line within 6 ft. (1.8 m) of the pump. All water
supply piping shall be made of materials and methods approved
by the local plumbing codes.
3-7 Prior to connecting water line to the SumpJet® purge the water
line to insure it is free from debris, solder, pie sealant, etc.
3-8 To connect the water line to the SharkBite® cut the pipe or tubing
end square. Ensure that there are no burrs or scratches 1” from
the cut end. Mark the pipe or tubing 1” from the cut end to
indicate proper insertion depth. If using PEX tubing the tube liner
in the end of the SharkBite® must be used. For copper and
CPVC piping the tube liner must be removed by using your
fingers or pliers. Insert the tubing or pipe into the SharkBite®
through the release collar to rest against the grab ring. Then
push the tube or pipe firmly until it reaches the tube stop. To
insure the tube or pipe is correctly inserted, check that the depth
mark is up to the end of the release collar.
3-9 If the Shark fitting is removed for connection to other types of
3/4” NPT threaded fittings, make sure all sealing tape is removed
from the threaded inlet of the SumpJet®. Use a small pick-type
tool if necessary. Do not allow any debris to enter the valve
body.
3-10 If reconnecting the SharkBite® or other
threaded fitting use PTFE (Teflon®) sealing tape only when
assembling threaded fittings into SumpJet® inlet.
3-11 Do not over tighten threaded inlet fitting, and
do not hold onto float plunger shroud when tightening.
3-12 DO NOT SWEAT PIPES OR FITTINGS
DIRECTLY CONNECTED TO THE SumpJet® . HEAT
TRANSFERRED FROM THE COPPER WILL DAMAGE
PLASTIC PARTS!
3-13 Determine the length of discharge pipe required to the discharge
exit point. Using schedule 40 PVC pipe, glue the discharge pipe
into the socket elbow of the SumpJet®. Complete all
discharge piping. Discharge piping should be routed to the yard
outside the building.
The bottom of the
grey pump housing
should be
approximately 12”
above the water
level at which the
normal sump pump
turns on.

NOTE: The SumpJet® comes complete with a foot valve. There is no
need to install a check valve on the discharge pipe.
NOTE: The foot valve has a removable poppet. Where freezing
discharge pipes are a problem, simply unscrew the strainer
screen, remove the poppet and spring, and replace the strainer.
The SumpJet® will now allow water to flow back into the pit,
eliminating discharge pipe freezing.
3-14 Turn the municipal water supply back on and open the shutoff valve.
Check for leaks. Test the SumpJet® to ensure that it is
operational. You will need to fill the sump pit with water by garden
hose or bucket.
3-15 Re-connect primary electric sump pump to power supply.
3-16 If you want to replace the sump cover it will be necessary to add
additional holes and slots to make access for the SumpJet®
suction pipe and float rod. Refer to template provided in Figure (4) at
the end of the manual.
3-17 If you cannot mount the SumpJet® to the pump discharge pipe you
may use a piece of wood to mount the SumpJet®. Cut holes as per
figure (4) at the end of the manual. There are 4 screw holes that you
can use to fasten the SumpJet® to the wood. Use #8x2.5" long
wood screws. Refer to Figure ( 3 )
