Well Point Installation
1. Install the control valve and pressure gauge in the pump body (see
Figure 1).

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 (see Figure 4).
3. 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

4. Mount the pump as close to the well as possible.
5. Use the fewest possible fittings (especially elbows) when connecting

should be at least as large as the suction port on the pump (include a
check valve – see Figure 5). 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 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 Page 8 for discharge pipe and tank connections.

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 (see Figure 4).
3. Mount the pump as close to the well as possible.
4. Assemble the foot valve, strainer, and well pipe (see Figure 6). Make
sure that the foot valve works freely.
5. 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.
6. Install a priming tee, priming plug, and suction pipe to the drop pipe
(see Figure 6). 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,
