SHALLOW WELL PUMP INSTALLATIONS
Surface Water Installation (Figure 3)
Possible contamination. Do not use
surface water for drinking. The installation
shown could be used for sprinkler applications.
1. The pump should be installed as close to the water
as possible, with the fewest possible ttings (especially
elbows) in the suction pipe. The suction pipe should
be at least as large as the suction port on the pump.
2. Assemble a foot valve and strainer to the suction pipe.
Make sure that the foot valve works freely. Use PTFE
pipe thread sealant tape or a PTFE-based pipe joint
compound on threaded pipe joints.
3. Install a screen to protect the water system from letting
debris enter the system.
4. Lower the pipe into the water until the strainer is ve
feet above the bottom. It should also be at least 10”
below the water level in order to prevent the pump
from sucking air. Strainer and pipe should be supported.
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. 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
water 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 can not pull water from well.
6. Joints must be air and water-tight. If the suction pipe
can suck air, the pump cannot pull water from the
water source.
7. See instructions on page 8 for connecting discharge
pipe to tank.
