7. Install enough plastic pipe in well casing to put ejector at the proper
depth. (Ask your well driller for this information.)
IMPORTANT: As a guide, the ejector should be set at least 10 to 20 feet
below the lowest water level with pump running, if possible, but always at
least five feet from the bottom of the well.
8. Tighten all hose clamps securely on plastic pipe. Use two clamps per
joint to prevent air leaks into suction pipe. Clamp screws should be on
opposite sides of the pipe. Fill pipes with water to make sure that foot
valve and connections do not leak.
9. Install sanitary well seal on top of well casing; use steel nipple through
well seal as shown in Figure 2.
IMPORTANT: Align locating lugs on adapter flange and pump base so that
pump discharge aligns with piping.
10. Install 1" (1-1/4") nipple in one side of adapter flange. Slide threadless
coupling down over drive pipe from well. Thread adapter flange onto

11. Slide threadless coupling up and secure nipple to drive pipe.
12. Remove paper backing from adhesive gasket. Apply gasket to adapter
flange, making sure that holes line up.
13. Align locating lugs on pump base with lugs on adapter flange; attach
pump to flange with cap screws provided.
14. See "Discharge Pipe Sizes" for information regarding correct discharge
pipe size.

SINGLE PIPE EJECTOR INSTALLATION
Single pipe installations require (see Figure 3):
a. Galvanized steel pipe
b. Leather packer-type ejector with built-in foot valve
c. Turned couplings (supplied with packer-type ejector)
5 Feet
d. Well casing adapter.
or more
1. Connect ejector to first length of pipe. Use pipe joint compound
sparingly on male threads. Consult Table II for proper venturi and
nozzle.
2. Lower pipe into casing. Use special turned couplings (included with
2357d 0797
2" single pipe ejector package) to increase water flow. Use pipe joint
compound sparingly on male couplings threads.
NOTICE: Fill pipe with water as each length is added to be sure foot valve
and connections do not leak.
3. Add lengths of pipe until the ejector reaches the proper depth. (Your
well driller should supply this information.)
IMPORTANT: As a guide, the ejector should be set at least 10 to 20 feet
below the lowest water level with pump running, if possible, but always at
least 5 feet above the bottom of the well.
4. To properly seat the cup seals, after the ejector is correctly positioned,
move the assembly up and down slightly. Water pressure in the casing
will then soak the cup seals. They should seal within 2-3 hours after
installation.
5. With ejector set, install well casing adapter. Align locating lugs and
tighten adapter to form seal with well casing.
