Installation
CASED WELL INSTALLATION, 2" OR
LARGER CASING (FIGURE 2)
1. Mount the pump as close to the well as possible.
2. Assemble the foot valve, strainer, and well pipe (see
Figure 2). 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 while the
pump is running in order to prevent the pump from
sucking air. Install a sanitary well seal.
4. Install a priming tee, priming plug, and suction pipe
to the pump (see Figure 2). Connect the pipe from the
well to the pump suction port, using the fewest possi-
ble fittings – especially elbows – as fittings increase
friction in the pipe (however, include a foot valve –
see Figure 2). The suction pipe should be at least as
large as the suction port on the pump. Use teflon tape
on threaded pipe joints. 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. Joints must be
air-tight and water-tight. If the suction pipe can suck
air, the pump cannot pull water from the well.
You have just completed the suction piping for your
new shallow well jet pump. Please go to Pages 5 and 6
for discharge pipe and tank connections.

INSTALLATION FOR SURFACE WATER
(FIGURE 3)
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 suction pipe (see Figure 3).
Make sure that the foot valve works freely. Use teflon
tape on threaded pipe joints. Protect the foot valve
assembly from fish, trash, etc, by installing a screen
around it (see Figure 3).
3. 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.
4. Install a priming tee, priming plug, and suction pipe
to the pump (see Figure 3). 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. Joints must be
air-tight and water-tight. If the suction pipe can suck
air, the pump cannot pull water from the well.
