New Deep Well Installation 7
4" OR LARGER WELL (Figure 10)
Step 1. Install the control valve and pressure gauge in the pump body. See
Figure 7.
Step 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.
Step 3. Mount the pump as close to the well as possible.
Step 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.
Step 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.
Step 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 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 11)
Step 1. Install the control valve and pressure gauge in the pump body. See
Figure 7.
Step 2. Mount the pump as close to the well as possible.
Step 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 cou-
plings to allow proper flow. Follow the instructions included with
the kit in order to match the nozzle and venturi to your well condi-
tions.
Step 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 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.
