4" Or Larger Well
1. Install the control valve and pressure gauge in the pump body. See
Figure 7.
2. Assemble ejector kit FP4800 (sold separately). See Figure 10. Follow
the instructions included with the kit in order to match the nozzle and
venturi to your well conditions.
3. Mount the pump as close to the well as possible.
4. Connect two pipes (1" drive, 1-1/4" suction) to the ejector and lower
the ejector into the well until it is five feet from the bottom. 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.
5. Install a sanitary well seal and connect the ejector piping to the pump.
Use steel nipples through the well seal with flexible poly pipe to avoid
crushing the plastic pipe when tightening the seal.
6. 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 double pipe deep well
jet pump. Please go to Page 8 for discharge pipe and tank connections.

3. Assemble ejector kit FP4840 (sold separately), well piping, and well
head adapter according to the instructions provided with the ejector
package. See Figure 11. Use galvanized drop pipe with turned
couplings to allow proper flow. Follow the instructions included with
the kit in order to match the nozzle and venturi to your well conditions.
4. Run two pipes (one smaller drive pipe, one larger suction pipe) from
the well 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 single pipe deep well
jet pump. Please go to Page 8 for discharge pipe and tank connections.
