Steel
Piping
The special
adapter
nipple
is not used with steel pip-
ing.
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 lOB). 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
which
may occur
in the piping
and foot valve as the
piping
is assembled.

Use pipe
joint compound
sparingly
on male threads.
2.
Lower
pipe
into casing.
Use special
turned
cou-
plings (included
with single pipe ejector
package)
to increase
water flow. Use pipe joint compound
sparingly
on male couplings
threads.
Horizontal
Offset
Pipe Sizes
When the pump
is set more than 25' to one side of the
well, increase
the horizontal
pipe size to reduce
fric-
tion. Never use pipe smaller than the pump
port size.

to be sure foot valve and connections
do not leak.
