4" OR LARGER WELL
1. Install the control valve and pressure gauge in the pump
body.
2. Assemble ejector kit FP4800 (sold separately). 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.
2" WELL
1. Install the control valve and pressure gauge in the pump
body.
2. Mount the pump as close to the well as possible.
3. Assemble ejector kit FP4840 (sold separately), well piping,
and well head adapter according to the instructions provided
with the ejector package. 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.
