large as the suction port on the
pump. Use teflon tape or a teflon-
based pipe joint compound on
threaded pipe joints. 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 teflon tape or a teflon 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 Pages 9 and 10 for
Discharge Pipe and Tank Connections.
INSTALLATION FOR SURFACE WATER
1. Install ejector kit (ejector is included
on Model 4RJ49 pump/tank system.
For other heavy-duty jet pumps, kits
are sold separately). Follow the
instructions provided with the kit.
Align the venturi with the top hole
on the front of the pump (See
Figure 8).
2. 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.
3. Assemble a foot valve and suction
pipe (See Figure 9). Make sure that
the foot valve works freely. Use
teflon tape or a teflon-based pipe
joint compound on threaded pipe
joints. Protect the foot valve
assembly from fish, trash, etc, by
installing a screen around it (See
Figure 9).
4. 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 while the
pump is running in order to prevent
the pump from sucking air.
5. Install a priming tee, priming plug,
and suction pipe to the pump (See
Figure 9). 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 water to the pump (high
spots can cause air pockets which can
air lock the pump). Seal the suction
pipe joints with teflon tape or a
teflon 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
source.
You have just completed the plumbing
for your new shallow well jet pump.

Discharge Pipe and Tank Connections.
NEW DEEP WELL
4” OR LARGER WELL (FIGURE 10)
1. Assemble ejector package 2P429A
(sold separately). See Figure 10.
Follow the instructions included with
the kit in order to match the nozzle
and venturi to your well conditions.
2. Mount the pump as close to the well
as possible.
3. Connect two pipes (1” drive, 1

ejector into the well until it is five
feet from the bottom. It should also
be at least 10 feet below the well’s
