Installation
Step 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.
Step 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 possible 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 PTFE pipe thread sealant
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
PTFE pipe thread sealant tape. Joints must be air-
and water-tight. If the suction pipe can suck air,
the pump cannot pull water from the well.

your new shallow well jet pump. Please go to

INSTALLATION FOR SURFACE WATER
(FIGURE 3)
Step 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 suc-
tion pipe should be at least as large as the suction
port on the pump.
Step 2. Assemble a foot valve and suction pipe (see
Figure 3). Make sure that the foot valve works
freely. Use PTFE pipe thread sealant tape on
threaded pipe joints. Protect the foot valve
assembly from fish, trash, etc, by installing a
screen around it (see Figure 3).
