New Shallow Well Installation 5
WELL POINT INSTALLATION (Figure 4)
Step 1. Install ejector kit FP4855 (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 3).
Step 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 penetra-
tion easier.
Step 3. Mount the pump as close to the well as possible.
Step 4. Use the fewest possible fittings (especially elbows) when connect-
ing the pipe from the well point to the pump suction port. The suc-
tion pipe should be at least as large as the suction port on the pump
(include a check valve – see Figure 4). 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, con-
sider 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
CASED WELL INSTALLATION, 2" OR LARGER
CASING (Figure 5)
Step 1. Install ejector kit FP4855 (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 3).
Step 2. Mount the pump as close to the well as possible.
Step 3. Assemble the foot valve, strainer, and well pipe (see Figure 5).
Make sure that the foot valve works freely.
Step 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.
Step 5. Install a priming tee, priming plug, and suction pipe to the pump
(see Figure 5). Connect the pipe from the well to the pump suction
port, using the fewest possible fittings – especially elbows – as fit-
tings increase friction in the pipe. The suction pipe should be at
least as 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
