WARNING
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 (Reduced Pressure
device/Reduced Pressure Zone device) backflow protection
device. Contact your local plumbing or water authority for
more information regarding the requirements for your
specific area.
CAUTION
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.
NOTICE
The SumpJet is designed for use with municipal water supply,
and is intended to be used as an emergency backup to an
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.
RISK OF ELECTRIC SHOCK
RISK OF SERIOUS INJURY OR DEATH
Recommended minimum water pressure (ahead of backflow
prevention device) = 30 psi (207kPa) with the valve open
(less pressure may not eject water from basement
adequately).
For nominal backflow protection, the SumpJet is
pre-equipped with an internal check valve certified to ASME
A112.18.3 and ASME A112.18.1/CSA B125.1.
Discharge of the SumpJet must not be connected to the
primary sump pump.
Discharge of the SumpJet must not 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 factory-equipped with a
SharkBite® push-type pipe connector. This fitting can be
used with various approved 3/4” potable water tubing and
pipe, such as PEX tubing (ASTM F876, CSA B137.5), copper
pipe (ASTM B 88), or CTS pipe (ASTM D 2846, CSA B137.6).
For more details on using the SharkBite, visit
www.sharkbite.com.
Do not use paste-type sealant 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 overtighten threaded inlet
fitting, and do not hold onto float plunger shroud when
tightening.
Purge water line prior to connection to SumpJet to ensure
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 water greater than 130 °F.

Pump Design
The Liberty Pumps SumpJet is designed for emergency backup to
an existing pump system. It uses the municipal water supply to
evacuate water from the sump. It is not intended to be used as the
primary sump water removal pump. It is intended to remove clear
sump water only.
Prolonged use of the SumpJet will result in increased municipal
water consumption. The SumpJet uses approximately 1 gallon of
water to remove 2 gallons of sump water, depending on elevation.
Optional Alarm
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. The model SJ10A-EYE features the
NightEye® Alarm for wireless alarm protection. If the model SJ10
was purchased without an alarm, an alarm (ALM-P1 or
ALM-P1-EYE) may be ordered from your local distributor or
contact Liberty Pumps for more information.

2.After mounting the SumpJet, prepare 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 per local codes and 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 local plumbing codes.
3.Prior to connecting the water supply line to the SumpJet,
purge the water line to ensure it is free from debris, solder,
pipe sealant, etc.
o connect the water supply line to the SharkBite, cut the pipe
4.T
or tubing end square. Ensure that there are no burrs or
scratches 1” from the cut end.
4a. 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 CTS piping, the tube liner
must be removed (use fingers or pliers).
4b. Insert
the tubing or pipe into the SharkBite through
the release collar to rest against the grab ring.
4c. Push the tube or pipe firmly until it reaches the
tube stop.
