New Shallow Well Installation 6
possible fittings – especially elbows – as fittings
increase friction in the pipe. The suction pipe should
be at least as large as the suction port on the pump.
Use teflon tape or a teflon-based pipe joint com-
pound 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 or a teflon
based pipe joint compound. Joints must be air- 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 Page 8 for
discharge pipe and tank connections.
INSTALLATION FOR SURFACE WATER
1. Install the control valve and pressure gauge in the
pump body (see Figure 7).
2. Install ejector kit FP4875 or 29650 (kits are sold sep-
arately). Follow the instructions provided with the kit.
Align the venturi with the top hole on the front of the
pump (see Figure 8).
3. 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.
4. Assemble a foot valve and suction pipe (see Figure
9). Make sure that the foot valve works freely. Use
teflon tape or a teflon-based pipe joint compound on
threaded pipe joints. Protect the foot valve assembly
from fish, trash, etc, by installing a screen around it
(see Figure 9).
5. 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.
6. Install a priming tee, priming plug, and suction pipe
to the pump (see Figure 9). 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 or a teflon
based pipe joint compound. Joints must be air- and
water-tight. If the suction pipe can suck air, the pump
cannot pull water from the well.

shallow well jet pump. Please go to Page 8 for discharge
