4" OR LARGER WELL (Figure 8)
Step 1. Assemble ejector kit (models with "J" suffix include complete ejec-
tor assembly; for other models, purchase ejector kit FP4855, sold
separately). See Figure 8. Follow the instructions included with the
kit in order to match the nozzle and venturi to your well condi-
tions.
Step 2. Mount the pump as close to the well as possible.
Step 3. 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.
Step 4. 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.
Step 5. 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 plumbing for your new double pipe deep
well jet pump. Please go to Page 8 for discharge pipe and tank connec-
tions.
2" WELL (Figure 9)
Step 1. Mount the pump as close to the well as possible.
Step 2. Assemble ejector kit (models with "J" suffix include complete ejec-
tor assembly; for other models, purchase ejector kit FP4855, sold
separately), well piping, and well head adapter according to the
instructions provided with the ejector package. See Figure 9. 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.
Step 3. 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 suc-
tion pipe joints with teflon tape or a teflon based pipe joint com-
pound. 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.
