INSTALLATION
Piping in the Well
The Shallow
Well Water
System
can be installed
on a dug well,
cased
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 lowest level to which
the water
will drop while
the pump
is operating
(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 u_mg a foot valve, a priming
tee and plug as shown in Figure
1, are recommended.

When
installed
on a driven

Well Water
System should have a check
valve installed
as shown in Figure 2A.

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 ex-
ceed 20 feet. This will be less ffthe pump is offset 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 ex-
ample, 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.

INSTALLATION
Pump
NOTICE:
Use Teflon tape supplied
with the pump
or Plasto-Jo'mt
Stik t 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 thl_ad stop in pump
portt
3. If leaks occur,
remove fittings,
clean off old tape, rewrap with
two to three layers of tape and remake
the connection.
If joint
still leaks, replace
the fittings (fittings
may be under_tzed).
4.
Be sure to support
all piping connected
to the System.
Horizontal
Piping from Well to Pump
When the pump is offset more than 25 feet from the well, hori-
zontal
suction
pipe size should
be increased
to reduce
friction
losses. Never install a suction pipe that is smager
than the suction
tapping
of the pump.
