INSTALLATION (Continued)
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 2. 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 2. 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 2. 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.
