Typical Pump Setup
Typical setups for lawn sprinkler pump systems
include ground water wells ( Fig. 1) or surface
water, such as lakes, ponds or streams. ( Fig. 3)
Location
For best performance, the pump must be located
as close to the water source as possible and
protected from the elements.
Ventilation
Ventilation and drainage must be provided to
prevent damage to the motor from heat and
moisture.
Freezing
The pump and all piping must be protected from
freezing. If freezing weather is forecast, drain
pump or remove completely from the sprinkler
system.
Water Supply
The water source must be able to supply enough
water to satisfy the capacity of the pump and
water needs. See performance chart.
WARNING: NEVER run pump against a
closed discharge. Doing so can boil water inside
pump, causing hazardous pressure in unit, risk
of explosion and possibly scalding persons
handling pump. ( Fig. 2)
Vertical Lift
Vertical lift is the vertical distance from the lowest
level of the water to the pump intake. The pump
will move water as long as the pump is within 25
vertical feet of the water source.
Horizontal Distance
The horizontal distance is the horizontal
measurement between the pump inlet and the
water source. This distance may affect the ability
of the pump to operate. If it is over 150 feet, call
customer service at 1-866-994-4148.
Pipe And Fittings
Use galvanized steel or NSF PW Schedule 40
PVC pipe and fittings. This material is designed
for water pressure and will seal against air
and water under pressure. Do Not Use: DWV
fittings, as these are designed for drains without
pressure and will not seal properly.

CAUTION: The entire system must be
air and water tight for efficient operation and to
maintain prime.
Wire Size:
The wire size is determined by the distance from
the breaker box to the pump motor, and the
horsepower rating of the motor. See the wire chart
for proper wire size.
