SINGLE PIPE EJECTOR INSTALLATION
Single pipe installations require (see Figure 8):
a. Galvanized steel pipe
b. Leather packer-type ejector with built-in foot valve
c. Turned couplings (supplied with packer-type ejector)
d. Well casing adapter.
Step 1. Connect ejector to first length of pipe. Use pipe joint compound
sparingly on male threads.
Step 2. Lower pipe into casing. Use special turned couplings (included
with 2” single pipe ejector package) to increase water flow. Use
pipe joint compound sparingly on male couplings threads.
NOTE:
Fill pipe with water as each length is added to be sure foot valve
and connections do not leak.
Step 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 (see Figure 8).
Step 4. To properly seat the cup seals, after the ejector is correctly posi-
tioned move the assembly up and down slightly. Water pressure in
the casing will then soak the cup seals (see Figure 8). They should
seal within 2-3 hours after installation.
Step 5. With ejector set, install well casing adapter. Remove pipe holder.
Align locating lugs and tighten adapter to form seal with well cas-
ing.
DISCHARGE PIPE SIZES
Step 1. If increasing discharge pipe size, install reducer in pump discharge
port. Do not increase pipe size by stages.
Step 2. When the pump is set away from the points of water use, the dis-
charge pipe size should be increased to reduce pressure losses
caused by friction.
• Up to 100 ft run: Same size as pump discharge port.
• 100 ft. to 300 ft run: Increase one pipe size.
• 300 ft. to 600 ft run: Increase two pipe sizes.
