New Shallow Well Installation

ALL 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 1).
Step 2. Install the ejector kit. Follow the instructions provided with the kit.
Align the venturi with the top hole on the front of the pump (see
Figure 3).

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 4).
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 5)
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 penetra-
tion 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 connect-
ing two or three well points to one suction pipe.

Step 6. Install a priming tee, priming plug, and suction pipe to the pump
(see Figures 4 and 5). 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 (include a check valve – see Figures 4 and 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 teflon tape or pipe joint com-
pound 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.
Step 7. Run piping from the discharge tee in the tank flange to the house-
hold piping. The discharge piping must be at least as large as the tank
tee. Install a relief valve in the discharge pipe capable of passing the
entire pump flow at 75 psi. Run a pipe from the relief valve to a floor
drain or some other convenient place to carry off the water.
You have just completed the piping for your new shallow well jet
pump/tank system. Please go to Page 7 for electrical connections.
