Installation (Continued)
2. Drive the well, using “drive
couplings” and a “drive cap”. “Drive
fittings” are threaded all the way
through and allow the pipe ends to
butt against each other so that the
driving force of the maul is carried
by the pipe and not by the threads.
The ordinary fittings found in
hardware stores are not threaded
all the way through the fitting and
can collapse under impact. “Drive
fittings” are also smoother than
standard plumbing fittings, making
ground penetration easier.
3. Mount the pump as close to the
well as possible.
4. Use the fewest possible fittings
(especially elbows) when connecting
the pipe from the well point to the
pump suction port. The suction pipe
should be at least as large as the
suction port on the pump (include a
check valve – See Figure 6). 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 pipe joint
compound approved for use on
PVC. Joints must be air- and water-
tight. If the suction pipe can suck
air, the pump cannot pull water
from the well. If one well point
does not supply enough water,
consider connecting two or three
well points to one suction pipe.
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.
CASED WELL INSTALLATION, 2” OR
LARGER CASING (FIGURE 7)
1. Install ejector package 2P429A
(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 5).
2. Mount the pump as close to the
well as possible.
3. Assemble the foot valve, strainer,
and well pipe (See Figure 7). Make
sure that the foot valve works
freely.
4. Lower the pipe into the well until
the strainer is five feet above the
bottom of the well. It should also be
at least 10 feet below the well’s
water level while the pump is
running in order to prevent the
pump from sucking air. Install a
sanitary well seal.
5. Install a priming tee, priming plug,
and suction pipe to the pump (See
Figure 7). 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
Models 4RJ47, 4RJ48, 4RJ49, 4RJ50, 4P035A and 4P036A
