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 PTFE pipe
thread sealant tape on male threads. Be sure that all suction pipe is

level (pump on)
3. 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 5
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 6.
Keep horizontal pipe run as short as possible. Use PTFE pipe thread
sealant tape on male pipe threads. Multiple well points may be
necessary to provide sufficient water to pump.
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 a suction 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 6. Be sure check valve flow arrow points toward pump.
DISCHARGE PIPE SIZES
745 0993
1. If increasing discharge pipe size, install reducer in pump discharge port.
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 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 de signed to deliver plenty
of water at full sprinkler pres sure. 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 7.
