PIPING IN THE DEEP WELL
See Figures 7 and 8.
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 Teflon 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 open-
ings while installing pump.
Step 3. Make sure foot valve operates freely: attach to ejector with a close
nipple. Use Teflon tape on male threads.
Step 4. Install nozzle and venturi in deep well ejector.
Step 5. Using Teflon tape on male threads, install special plastic pipe
adapter (supplied with ejector) by screwing adapter into 1-1/4”
tapped hole in ejector body (see Figure 7A).
Step 6. Thread a 1” plastic pipe adapter into the 1” tapped hole in ejector
body (see Figure 7A).
Step 7. Install sufficient plastic pipe in well casing to place ejector at 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 possi-
ble, but always at least five feet from the bottom of the well.
Step 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.
Step 9. Install sanitary well seal on top of well casing; use steel nipple
through well seal as shown in Figure 7A.
IMPORTANT: align locating lugs on adapter flange and pump base
so that pump discharge will be aligned with piping.
Step 10. Install 1” nipple in one side of adapter flange. Slide threadless
coupling down over drive pipe from well. Thread adapter flange
onto suction pipe from well and align nipple and drive pipe.
Step 11. Slide threadless coupling up and secure nipple to drive pipe.
Step 12. Remove paper backing from adhesive gasket. Apply gasket to
adapter flange, making sure that holes line up.
Step 13. Align locating lugs on pump base with locating lugs on adapter
flange; attach pump to flange with cap screws provided.
Step 14. See “Discharge Pipe Sizes” for information regarding correct dis-
charge pipe size.
