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 2. 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.
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 3.
Do not use in a pressure tank or booster pump application.

PUMP INSTALLATION

NOTICE: Use only PTFE pipe thread sealant tape for making all threaded
connections to the pump itself. Do not use pipe joint compounds on
plastic pumps: they can react with the plastic in the pump components.
Make sure that all pipe joints in the suction pipe are air tight as well as
water tight. If the suction pipe can suck air, the pump will not be able to
pull water from the well.

1. Bolt pump to solid, level foundation.
2. Support all piping connected to the pump.
3. Wrap 1-1/2 to two layers of PTFE pipe thread sealant 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 overtighten.
NOTICE: Install pump as close to well head as poss ible. 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 1. For driven point
installations, install a check valve as shown in Figure 2. Be sure check
valve flow arrow points toward pump.
Use schedule 80 or iron pipe. See "Well Pipe In stalla tion" for more
information.
