Installation
NOTICE: Use the installation method below which
matches your well type.
CASED WELL INSTALLATION
1.
Inspect foot valve to be sure it works freely. Inspect
strainer to be sure it is clean.
2
Connect foot valve and strainer to the first length of
suction pipe and lower pipe into well. Add sections
of pipe as needed, using Teflon tape on male
threads. Be sure that all suction pipe is leakproof or
pump will lose prime and fail to pump. Install foot
valve 10 to 20 feet below the lowest level to which
water will drop while pump is operating (pumping
water level). Your well driller can furnish this
information.
.
To prevent sand and sediment from entering the
pumping system, the foot valve/strainer should be
at least 5 feet above the bottom of the well.
4. When the proper depth is reached, install a sanitary
well seal over the pipe and in the well casing.
Tighten the bolts to seal the casing.
5. When using a foot valve, a priming tee and plug as
shown in Figure 6 are recommended.
DUG WELL INSTALLATION
Same as cased well installation.
DRIVEN POINT INSTALLATION
1. Connect the suction pipe to the drive point as
illustrated in Figure 7. Keep horizontal pipe run as
short as possible. Use Teflon tape on male pipe
threads. Multple well points may be necessary to
provide sufficient water to pump.

Figure 8--Multiple Discharge
2. Install a check valve in horizontal pipe. Flow arrow
on check valve must point toward pump.
HORIZONTAL PIPING FROM WELL TO PUMP
1. Never install asuction pipe that is smaller than the
suction port of the pump.
2. To aid priming on well point installations, install a
line check valve as shown in Figure 7. Be sure
check valve flow arrow points toward pump.
DISCHARGE PIPE SIZES
1.
If increasing discharge pipe size, install reducer in
pump discharge port. Do not increase pipe size by
stages.
.
When the pump is set away from the points of water
use, the discharge pipe size should be increased to
reduce pressure losses caused by friction•
e Up to 100' run: Same size as pump discharge
port•
• 100' to 300' run: Increase one pipe size.
• 300' to 600' run: Increase two pipe sizes.
LAWN SPRINKLING APPLICATION
This pump is designed for lawn sprinkling. It is
designed to deliver plenty of water at full sprinkler
pressure. It can pump from a pond, cistern or well
points.
Pump discharge can be divided to supply two (2) or
more sprinkler systems. A suggested multiple dis-
charge to service is shown in Figure 8.
Do not use in a pressure tank or booster pump
application.

PUMP INSTALLATION
NOTICE: Use Teflon tape supplied with the pump for
making all threaded connections to the pump itself. Do
not use pipe joint compounds on the pump: they can
react with the plastic in the pump components,
1. Bolt pump to solid, level foundation.
2. Support all piping connected to the pump.
3. Wrap 11/2to two layers of Teflon tape clockwise (as
you face end of pipe)on all male threads being
attached to pump.
4. Tighten joints hand tight plus 1Vz turns. Do not
overtighten.
NOTICE: Install pump as close to well head as
possible. Long piping runs and many fittings create
friction and reduce flow.
NOTICE: For long horizontal pipe runs, install a
priming tee between check valve and well head as
shown in Figure 6. For driven point installations, install
a check valve as shown in Figure 7. Be sure check
valve flow arrow points toward pump.
Use schedule 80 or iron pipe. See "Well Pipe Installa-
tion" for more information.

Figure 15--Remove Priming Plug
Figure 16--Fill Pump Before Starting
PRIMING THE PUMP
NOTICE: 'Priming' refers to the pump expelling all air
in the system and beginning to move water from its
source out into the system. It does not refer only to
pouring water into the pump (although pouring water
in is usually the first step).
NOTICE: NEVER runpump dry. Running pump without
water in it willdamage seals and can melt impeller and
diffuser. To prevent damage, fill pump with water
before starting.
1. Remove priming plug (Figure 15).
2. Make sure suction and discharge valves and any
hoses on discharge side of pump are open.
3. Fill pump and suction pipe with water.
4. Replace priming plug, using Teflon tape on thread;
tighten plug.
NOTICE: If a priming tee and plug have been
provided for a long horizontal run, be sure to fill
suction pipe through this tee and replace PlUg.
(Dont' forget to Teflon tape the plug.)
5. Start pump: water should be produced in 10minutes
or less, the time depending on depth to water (not
more than 20') and length of horizontal run (10' of

friction losses in the pipe).
If no water is produced within 10 minutes, stop
pump, release all pressure, remove priming plug,
refill and try again.
[_kWARNING] Hazardous pressure and risk of ex-
plosion and scalding. If pump is run continuously at
no flow (that is, with discharge shut off or without
priming), water may boil in pump and piping system.
Under steam pressure, pipes may rupture, blow offof
fittings or blow out of pump ports and scald anyone
near.
To prevent explosion, do the following:
A. Be sure discharge (valve, pistol grip hose nozzle,
etc.) is open whenever pump is running.
B. If pump fails to produce water when attempting to
prime, release all pressure, drain pump and refill
with cold water after every two attempts.
C. When priming, monitor pump and piping tempera-
ture. If pump or piping begin to feel warm to the
touch, shut off pump and allow system to cool off.
Release all pressure in system and refill pump and
piping with cold water.
