Installation 5
DRIVEN POINT INSTALLATION
Step 1. Connect suction pipe to drive point (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.
Step 2. Install check valve in horizontal pipe. Flow arrow
on check valve must point toward pump.
HORIZONTAL PIPING
FROM WELL TO PUMP
Step 1. Pump performance will be decreased if suction
pipe is smaller than the pump suction port. Use
1-1/2” suction pipe for 1 and 1-1/2 HP pumps. Use
2” suction pipe for 2 HP pumps.
Step 2. To aid priming on well point installations, install
line check valve. Be sure check valve flow arrow
points toward pump.
DISCHARGE PIPE SIZES
Discharge pipe size should be increased to reduce
pressure losses caused by friction on long pipe runs.
• Up to 100' (30.5 m) run: Same size as pump
discharge port.
• 100' - 300' (30.5 - 91.4 m) run: Increase one pipe size.
• 300' - 600' (91.4 - 182.9 m) run: Increase two
pipe sizes.
LAWN SPRINKLING APPLICATION
This pump is designed for lawn sprinkling. Delivers plenty
of water at full sprinkler pressure. Pumps from pond,
cistern or well points.
Pump discharge can be divided to supply 4 or more
sprinkler zones.
Do not use in booster pump applications.
PUMP/PIPING INSTALLATION
Use rigid pipe. Do not use hose or plastic tubing.
NOTICE: Use only Teflon tape or Teflon based joint
compounds 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 pump compo-
nents. 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.
Step 1. Bolt pump to solid, level foundation.
Step 2. Support all piping connected to pump.
Step 3. Wrap 1-1/2 to 2 layers of Teflon tape clockwise
(as you face end of pipe) on all male threads being
attached to pump.
Step 4. Tighten joints hand tight plus 1-1/2 turns.
Do not overtighten.
Step 5. Replace prime plug with pressure gauge. This will
aid in sizing zones, troubleshooting, and following
pump performance chart.
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 (Fig. 1). For driven
point installations, install check valve. Be sure that check
valve flow arrow points toward pump.
