Pentair STA-RITE MS Series User Manual

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.
NOTICE: 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
positioned 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. Re move pipe holder.
Align locating lugs and tighten adapter to form seal with well casing.
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
discharge pipe size should be increased to reduce pressure losses
caused by friction.
