Installation
DEEP WELL / DOUBLE PIPE
PIPING IN THE DEEP WELL (Figures 3 & 4)
NOTICE: Deep well installations are either single pipe
(2" wells) or double pipe (4" and larger wells). In a dou-
ble 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).
Suction pipe always aligns with center of pump.
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 installation and removal.
PLASTIC PIPE INSTALLATION –
DOUBLE PIPE (Figures 3 & 4)
NOTICE: Use Teflon tape on all male threads on plastic
pipe and fittings to prevent air leaks in suction piping.
1. Inspect jet to make sure that nozzle and venturi
openings are clean and clear.
2. Inspect pipe for any foreign matter or obstructions.
IMPORTANT: Make sure that no foreign matter enters
pipe openings while installing pump.
3. Make sure foot valve operates freely: attach to jet
with a close nipple. Use Teflon tape on male threads.
4. Install nozzle and venturi in deep well jet. Consult
Table II for proper nozzle and venturi.
5. Using Teflon tape on male threads, install special
plastic pipe adapter (supplied with jet package) by
474 0194

screwing adapter into 1-1/4" tapped hole in ejector
body.
6. Thread a 1" plastic pipe adapter into the 1" tapped
hole in jet body.
7. Install sufficient plastic pipe in well casing to place
jet at the proper depth. (Your well driller should sup-
ply this information.)
IMPORTANT: As a guide, the jet should be set at least
10 to 20 ft. (3-6M) below lowest water level with
pump running, but always at least 5 ft. (1.5M) from
bottom of well.
8. Tighten hose clamps on plastic pipe. Use 2 clamps
per joint to prevent air leaks into suction pipe. Clamp
screws should be on opposite sides of pipe. Fill pipes
with water to make sure foot valve and connections
do not leak.
9. Install sanitary well seal on top of well casing; use
steel nipple through well seal.
IMPORTANT: Align locating lugs on adapter flange
and pump base so pump discharge will be aligned
with piping.
10. Install nipple in drive pipe 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.
11. Slide threadless coupling up and secure nipple to
drive pipe.
