INSTALLATION
Piping in the Well
The
Shallow
Well Water
System
can be installed
on a dug
well, drilled
well or with
a driven
point.
In a dug or cased
well,
a foot valve and strainer
should
be installed
for easy
priming.
It should
be installed
five to ten feet below
the low-
est level to which
the water will drop while the pump
is op-
erating
(pumping
water
level).
To keep
sediment
from
clogging
the strainer,
be sure it is five to ten feet above
the
bottom
of the well.
Before
installing
the foot valve,
make
sure that it works
freely.
When
using a foot valve, a priming
tee and plug as shown
in
Figure 1, are recommended.

To Service
From
Well
For a pump at sea level mounted directly over the well, be
sure the total lift from the pumping water level to the pump
does not exceed 20 feet. This will be less if the pump is off-
set from the well.
The maximum
lift of any pump decreases
at the rate of about
1' less lift for every 1,000 feet of elevation
above
sea level.
For example,
at Denver,
Colorado
(Elev. 5,000')
the pump
loses five feet of lift. The maximum
depth
from
which
it
would
pump
water
would
therefore
be 15 feet.

NOTICE:
Use Teflon tape supplied
with the pump
or Plasto-
Joint
Stik' for making
all pipe-thread
connections
to the
pump
itself. To avoid stress-cracking,
do not use pipe joint
compounds
on the pump.
1. Wrap
male pipe threads
being attached
to pump
with
one or two layers of Teflon
tape. Cover entire
threaded
portion
of pipe.
2. Do not overtighten
threaded fittings in the plastic pump.
Be sure you do not try to tighten joint past thread stop
in pump
port!
3. If leaks occur, remove fittings, clean off old tape, rewrap
with
two to three
layers
of tape and remake
the con-
nection.
If joint still leaks,
replace
the fittings
(fittings
may be undersized).
4. Be sure to support
all piping
connected
to the System.
'Lake Chemical Co., Chicago, Illinois
Horizontal
Piping from
Well
to Pump
When
the pump
is offset more
than 25 feet from the well,
horizontal
suction
pipe size should
be increased
to reduce
friction
losses.
Never
install
a suction
pipe that is smaller
than the suction
tapping
of the pump.
