working on pump or motor.
1. Drain and remove the old pump. Check the old pipe for
scale, lime, rust, etc., and replace it if necessary.
2. Install the pump in the system. Make sure that all pipe
joints in the suction pipe are air-tight as well as water
Cased Well Installation (Figure 1)
1. Mount the pump as close to the well as possible.
2. Assemble the foot valve, strainer, and well pipe.
Make sure that the foot valve works freely.
3. 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.
4. Install a sanitary well seal.
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. See instructions on page 8 for connecting discharge
pipe to tank.

tight. If the suction pipe can suck air, the pump will not
be able to pull water from the well.
3. Adjust the pump mounting height so that the plumbing
connections do not put a strain on the pump body.
Support the pipe so that the pump body does not take
the weight of piping or fittings.
