4. Install venturi in ejector body. Venturi threads into second
set of threads in ejector discharge port (over nozzle). End
of venturi will extend out of port when it is installed (See
Figure 4).
5. Install check valve and strainer on end of ejector body with
one port (bottom of ejector - See Figure 5).
6. Wrap 1-1/2 turns of PTFE pipe thread sealant tape
onto threaded end of pipe adapter. Thread long adapter
(furnished) into ejector discharge port (slide it over
venturi to install). Tape and install short adapter (not
furnished - purchase locally) in drive port (See Figure 6).
Adapters must be tight - if assembly leaks, pump will not
lift water from well.

4" cased (Drilled) Well
1. Determine length of flexible plastic pipe needed to locate
ejector at proper depth (your well driller should supply
this information). Measure carefully and cut suction
(1-1/4") and drive (1") pipes to length.
note: As a guide, set ejector 10 to 20 feet below lowest
water level reached with pump running, but always at least
five feet above bottom of well (See Figure 7).

At least 5 Feet

2. Connect plastic pipes to adapters with hose clamps
(See Figure 8); use two clamps per joint. Put tightening
screws on opposite sides of pipe as shown.
note: Clamp pipe securely and only use clamps that are
all stainless steel.

3. Install steel nipples in sanitary well seal.
note: To allow correct alignment of pipes with pump ports,
1-1/4" (suction) pipe must run above 1" (drive) pipe. Adjust
height of nipples in well seal to allow for this.
4. Use pipe couplings and adapters to connect nipples to
plastic pipe (See Figure 9). PTFE pipe thread sealant
tape all threaded joints to prevent leaks.
note: CLAMP PIPE SECURELY; clamps must hold weight
of pipes, ejector, and water in pipes. In a 110' well, this can
be more than 100 lbs.
