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 suc-
tion 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 low-
est level to which water will drop while pump is operat-
ing (pumping water level). Your well driller can furnish
this information.
3. To prevent sand and sediment from entering the pump-
ing 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 5 are recommended.
DUG WELL OR OPEN WATER
INSTALLATION
1. Follow cased well installation, steps 1, 2, 3 and 5.
DRIVEN POINT INSTALLATION
1. Connect the suction pipe to the drive point as illustrated
in Figure 6. Keep horizontal pipe run as short as possible.
Use Teflon tape on male pipe threads. Multiple well
points may be necessary to provide sufficient water to
pump.
2. Install a check valve in piping as shown in Figure 6. Flow
arrow on check valve must point toward pump.
HORIZONTAL PIPING FROM WELL TO
PUMP
1. Never install a suction pipe that is smaller than the suc-
tion tapping of the pump.
2. To aid priming on driven point installations, install a line
check valve as shown in Figure 6. Be sure check valve
flow arrow points toward pump.
DISCHARGE PIPE SIZES
1. If increasing discharge pipe size, install reducer in pump
discharge tapping. Do not increase pipe size by stages.
2. 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.
• Up to 100’ run: Same size as pump discharge tapping.
• 100’ to 300’ run: Increase one pipe size.
• 300’ to 600’ run: Increase two pipe sizes.
