BEFORE YOU INSTALL YOUR PUMP
Pump
NOTE: For proper performance, pump MUST be matched to ejector and

depth to water.
Step 1. Long runs and many fittings increase friction and reduce flow.
Threadless Coupling
Locate pump as close to well as possible: use as few elbows and
fittings as possible.

Step 2. Be sure well is clear of sand. Sand will plug the pump and void

the warranty.
Step 3. Protect pump and all piping from freezing. Freezing will split pipe,
damage pump and void the warranty. Check locally for frost pro-

tection requirements (usually pipe must be 12" below frost line
and pump must be insulated).
1-1/4" Suction Pipe
Step 4. Be sure all pipes and foot valve are clean and in good condition.
Step 5. No air pockets in suction pipe.
Step 6. No leaks in suction pipe. Use PTFE pipe thread sealant tape to seal

pipe joints.
Step 7. Unions installed near pump and well will aid in servicing. Leave
room to use wrenches.

Step 8. Plug 1" drive port when installing on shallow well.
IMPORTANT: Flow into well must at least equal flow out through

PIPING IN THE DEEP WELL
See Figures 1 and 2.
NOTE: Deep well installations are either single pipe (2" wells) or double
pipe (4" and larger wells). In a double pipe installation, the larger pipe is
the suction pipe and the smaller pipe is the drive pipe (very deep wells may
use suction and drive pipes of the same diameter).
Plastic pipe is ideal for double pipe installations. Due to its light weight, it
is easy to handle and does not usually require a block and tackle for instal-
lation and removal.
PLASTIC PIPE INSTALLATION – DOUBLE PIPE
NOTE: Use PTFE pipe thread sealant tape on all male threads on plastic
pipe and fittings to prevent air leaks in suction piping.
Step 1. Inspect ejector to make sure that nozzle and venturi openings are
clean and clear.
Step 2. Inspect pipe for any foreign matter or obstructions.
IMPORTANT: Make sure that no foreign matter enters pipe openings while
installing pump.
Step 3. Make sure foot valve operates freely: attach to ejector with a close
nipple. Use PTFE pipe thread sealant tape on male threads.
Step 4. Install nozzle and venturi in deep well ejector.
Step 5. Using PTFE pipe thread sealant tape on male threads, install spe-
cial plastic pipe adapter (supplied with ejector) by screwing adapt-
er into 1-1/4" tapped hole in ejector body (see Figure 1).
Step 6. Thread a 1" plastic pipe adapter into the 1" tapped hole in ejector
body (see Figure 1).
