Install a priming tee, priming plug, and suction pipe to
the drop pipe. If the distance from the well to the pump is
substantial, add a priming tee at the pump. Connect the pipe
from the well to the pump suction port, using the fewest
possible fittings – especially elbows – as fittings increase
friction in the pipe. The suction pipe should be at least as
large as the suction port on the pump. Support the pipe so
that there are no dips or sags in the pipe, so it doesn't strain
the pump body, and so that it slopes slightly upward from
the well to the pump (high spots can cause air pockets which
can air lock the pump). Seal the suction pipe. joints with
PTFE pipe thread sealant tape or a PTFE-based pipe joint
compound. Joints must be air- and water-tight. If the suction
pipe can suck air, the pump cannot pull water from the well.
You have just completed the suction piping for your new shallow
well jet pump. Please go to Page 8 for discharge pipe and
tank connections.
INSTALLATION FOR SURFACE WATER
Possible contamination. Do not use surface water
for drinking. The installation shown could be used for sprinkler
applications.
1.
Install the control valve and pressure gauge in the
pump body.
2.
Install ejector kit FP4855 with a Series 4200 pump, or kit
FP4875 with a Series 4300 pump (kits are sold separately).
Follow the instructions provided with the kit. Align the
venturi with the top hole on the front of the pump.
3.
The pump should be installed as close to the water as
possible, with the fewest possible fittings (especially elbows)
in the suction pipe. The suction pipe should be at least as
large as the suction port on the pump.
4.
Assemble a foot valve and suction pipe. Make sure that the
foot valve works freely. Use PTFE pipe thread sealant tape or
a PTFE-based pipe joint compound on threaded pipe joints.
Protect the foot valve assembly from fish, trash, etc, by
installing a screen around it.
5.
Lower the pipe into the water until the strainer is five feet
above the bottom. It should also be at least 10 feet below the
water level in order to prevent the pump from sucking air.
6.
Install a priming tee, priming plug, and suction pipe to the
pump. Support the pipe so that there are no dips or sags in
the pipe, so it doesn't strain the pump body, and so that it
slopes slightly upward from the well to the pump (high spots
can cause air pockets which can air lock the pump). Seal the
suction pipe joints with PTFE pipe thread sealant tape or a
PTFE-based pipe joint compound. Joints must be air- and
water-tight. If the suction pipe can suck air, the pump cannot
pull water from the well.
You have just completed the plumbing for your new shallow well
jet pump. Please go to Page 8 for discharge pipe and
tank connections.
