INSTALLATION (Continued)
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.
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

Do not use in a pressure tank or booster pump
application.
Pump/Piping Installation
PUMP INSTALLATION
NOTICE: Use Teflon tape supplied with the pump for mak-
ing 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 1-1/2 to 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 1-1/2 turns. Do not over-
tighten.
NOTICE: Install pump as close to water source as possible.
Long piping runs and many fittings create friction and re-
duce flow.
Use schedule 80 or iron pipe. See "Well Pipe Installation" for
more information.
