Step 1. The pump should be installed as close to the water as possible,

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 fit-
tings 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.

well jet pump. Please go to Page 6 for discharge pipe and tank
connections.
