Deep Well (Single Pipe System)
Application - Where pumping water level is
greater than 25 feet and inside diameter of well is
2, 2-1/2 or 3 inches. ( Fig 1)
On single pipe deep well installations, clean,
sound well casing must be used to give a tight
seal.
NOTE: This application requires a well adapter
for the top of the well.
NOTE: Pre-soak packer leathers for
approximately two hours before installation.
1. Attach foot valve directly to bottom of ejector
assembly. Ejector must be submerged 10 to
15 feet below pumping water level and the
foot valve must be at least five (5) feet from
bottom of well.
2. Attach foot valve and packer ejector to
suction pipe (presoak packer leathers for
approximately two (2) hours). Push the
assembly down the well. Some force may be
required to push the ejector down the casing.
3. As each section is lowered, check for leaks by
pouring water into the suction pipe.
4. Attach well adapter to suction pipe, lower over
casing top and tighten adapter flange.
5. If no leaks are found, proceed to WELL TO
PUMP CONNECTION (SUCTION PIPE) using
piping of the same diameter as the suction
pipe (1-1/4”) and pressure pipe (1”) tappings
of the pump. For long offset distances, see
chart on page 9 for the proper pipe size.
6. Unions in suction and discharge piping near
pump and well will aid in servicing. Be sure
to leave enough surrounding room so that
wrenches can be used easily.

INSTALLING PIPING IN WELL (CONTINUED)
WELL TO PUMP CONNECTION (SUCTION PIPE)
Shallow Well Application Only:
CAUTION: Dry-fit entire assembly to ensure proper fit before gluing or taping parts.
CAUTION: Follow all proper gluing procedures as specified by the glue manufacturer. Always
glue in a vertical direction whenever possible to prevent glue from dripping inside pipe or fittings
CAUTION: Use pipe tape and pipe paste compound on all male threads. Tighten with wrench to
a snug fit and add another 1/4 turn to ensure proper seal.

3. The use of a union (optional) will assist with
easy connection and disconnect. (Fig. 3)

2. Make the connection to your well. Wrap all
threaded fittings with pipe tape 5 times or
apply a pipe paste (pipe dope) to ensure an air
tight connection. (Fig. 2)
1. Attach ejector to face of pump with two (2)
bolts and gasket provided. Venturi tube on the
ejector inserts into the top tapping of the face
of the pump (Fig. 1).

is required in the well at the end of the pipe
to maintain prime. ( Fig 4a)
