6. Thread a 1" plastic pipe adapter or a 1" nipple into
the 1" tapped hole in ejector body (see Figure 8).
7. Install sufficient plastic pipe in well casing to place
ejector at the proper depth. (Your well driller
should supply this information.)
NOTICE: 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 five feet from
the bottom of the well.
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.
9. Install sanitary well seal on top of well casing; use
steel nipple through well seal as shown in Figure 6.
NOTICE: Align locating lugs on adapter flange and
pump base so that pump discharge will be aligned with
piping.
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.
11. Slide threadless coupling up and secure nipple to
drive pipe.

12. Remove paper backing from adhesive gasket. Apply
gasket to adapter flange, making sure that holes line
up.
13. Align locating lugs on pump base with locating lugs
on adapter flange; attach pump to flange with cap
screws provided.
14. See "Discharge Pipe Sizes" for information regard-
ing correct discharge pipe size.
Steel Piping
The special adapter nipple is not used with steel piping.
To more safely lower steel piping into the well, build a
tripod out of 2x4 lumber. A couple of pipe clamps can
also be made of 2x4s secured with 1/2" bolts (see
Figure 10B). Always install the coupling at the top end
of the pipe joint and install the pipe clamp below the
coupling. This will prevent accidentally dropping the
pipe into the well if the clamp slips. With steel pipe,
be sure all joints are clean and the ends reamed before
installing; use teflon tape or pipe joint compound at
each joint to prevent leakage.
Use a lever hoist (a "come-along") to lower pipe into
well (see Figure 10A). As each section of piping is low-
ered into the well, fill it with water. This will help
prime the system and also serves as a check on leaks
