SHALLOW WELL PUMP INSTALLATIONS
Driven Point Installation (Figure 2)
1. Drive the well point, using “drive couplings” and a “drivecap”.
“Drive ttings” 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 ttings found in hardware stores are not threaded
all the way through the tting and can collapse under impact.
“Drive ttings” are also smoother than standard plumbing
ttings, making ground penetration easier.
2. Mount the pump as close to the well as possible.
3. Use the fewest possible ttings (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.
4. Install a check as shown.
5. Install a priming tee, priming plug, and pressure gauge
to pump’s discharge port. Connect the pipe from the
well to the pump’s suction port, using the fewest
possible ttings-especially elbows. 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 not to strain the pump body, and so that it
slopes slightly upward from the well to the pump
(Note: Not doing so can create air locks preventing
the pump from working properly). Seal the suction
pipe joints with PTFE pipe thread sealant tape or a
PTFE based pipe joint compound. Joints must be air
and water tight. If the suction pipe can suck air,
the pump cannot pull water from well.
6. If one well point does not supply enough water,
consider connecting two or three well points to one
suction pipe.
7. See instructions on page 8 for connecting discharge
pipe to tank.
