Figure 1. Typical Installation
Tighten hose clamps
The bottom of the gray
pump housing should be
approximately 12–16”
above the water level at
which the primary sump
pump turns on.
DISCHARGE
1. Using the hose clamps provided, mount the SumpJet to the
existing discharge pipe. Place the unit so the float level will
operate a few inches above the turn-on level of the primary
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 in Step 10.
Figure 2. SumpJet Placement
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.
4. T
o connect the water supply line to the SharkBite, cut the pipe
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 CPVC 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.
4d. T
o ensure the tube or pipe is correctly inserted,
check that the depth mark is up to the end of the
release collar.
5. If the SharkBite 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.
NOTICE
 If reconnecting the SharkBite or other threaded fitting, 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.
 Do not sweat pipes or fittings directly connected to the
SumpJet. Heat transferred from the copper will damage
plastic parts.
6. Determine the length of discharge pipe required to the
discharge exit point. Using schedule 40 PV
C 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.
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.
