Shallow Well Installations
Step 1. Remove the control valve from the pump body. Replace it with a
1" NPT close nipple, a 1"x1"x3/4" NPT Tee, and a 1" NPT pipe
plug (see Figure 1). Install the pressure gage in the plugged hole in
the pump body (see Figure 4).
Step 2. Install the ejector kit. Follow the instructions provided with the kit.

Step 3. Mount the pump as close to the well as possible. 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.
Step 4. Assemble the foot valve, strainer, and well pipe (see Figure 7). Make
sure that the foot valve works freely.
Step 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.
Driven Point Installation (Figure 8)
Step 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 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.
Step 4. Mount the pump as close to the well as possible.
Step 5. If one well point does not supply enough water, consider
connecting two or three well points to one suction pipe.

pockets which can air lock the pump).

pipe can suck air, the pump cannot pull water from the well.
