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 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
Possible contamination. Do not use surface water for drinking.
The installation shown could be used for sprinkler applications.
1. Install the control valve and pressure gauge in the pump body.
2. Install ejector kit FP4855 with a Series 4200 pump, or kit FP4875 with
a Series 4300 pump (kits are sold separately). Follow the instructions
provided with the kit. Align the venturi with the top hole on the front of
the pump.
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. Make sure that the foot valve
works freely. Use PTFE pipe thread sealant tape or a PTFE-based pipe
joint compound on threaded pipe joints. Protect the foot valve assembly
from fish, trash, etc, by installing a screen around it.
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.
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 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 thewell.
You have just completed the plumbing for your new shallow well jet pump.
