INSTALLATION
5
Lawn Sprinkling Application
This pump is designed for lawn sprinkling. When prop-
erly installed it will deliver adequate water and pressure
from any well source.
Pump/Piping Installation
If turning pump on and o by pressure, a pressure
switch and tank are required. For proper installation,
follow tank and switch instructions or contact a qualied
plumber/electrican.
Use rigid pipe. Do not use hose or plastic tubing. See
“Well Pipe Installation” for more information.
NOTICE
Use only PTFE pipe thread sealant tape to joint com-
pounds 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 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 pump.
3. Wrap 1-1/2 to 2 layers of Teon 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.
5. Replace prime plug with pressure gauge. This will aid
in sizing zones, troubleshooting, and following pump
performance chart.
NOTICE
For long horizontal pipe runs, install a priming tee
between check valve and well head (Fig. 1).
Pipe from Well to Pump
1. Pump performance will be decreased if the pipe
diameter is less than the inlet size of the pump. In
proper installation, the pipe size equals the inlet size.
2. To aid priming on well point installations, install line
check valve. Be sure check valve ow arrow points
toward pump.
Pipe from Pump to Sprinkler Heads
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 dis
charge 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.
