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 fittings (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 five
feet above the bottom. It should also be at least 10
feet below the water level in order to prevent the pump
from sucking air.
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 fittings-especially elbows – to reduce 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. 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.
