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 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 sprinkler sys-
tems. A suggested multiple discharge to service is shown in Figure 3.
Do not use in a pressure tank or booster pump application.
PUMP INSTALLATION
NOTICE:
Use only Teflon tape or Teflon based joint compounds for making
all threaded connections to the pump itself.
Do not use pipe joint com-
pounds on plastic pumps:
they can react with the plastic in the pump com-
ponents. 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 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 overtighten.
NOTICE:
Install pump as close to well head as possible. 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 installa-
tions, 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 Installation” for more
information.
