C. Select Sprinkler Heads
There are three basic types of sprinklers for residential use: large
area rotors, rotating stream spray sprinklers and small area fan
spray sprinklers. Large area rotors and rotating stream spray sprin-
klers should never be installed on the same zone as small area fan
spray sprinklers. High efficiency
spray nozzles such as Pro-Spray

should be
considered in place of traditional
spray nozzles.
1. Large area rotors will cover areas that measure 8 meters
by 8 meters and larger.
2. Small area sprays are typically used in areas smaller than
8 meters by 8 meters.
Within both of these groups are pop-up sprinklers which are
installed even with the ground level, and riser-mounted shrub
heads, which are installed above ground level.
This 8 meters by 8 meters measurement is not a hard rule, rather
it is a guideline. The only consideration restricting the size of
the area in which spray heads (small area sprinklers) can be used
is economics. If a large area or mid-range rotor can be used, it
usually means less pipe, fewer valves and a smaller controller will
be required to complete the job.
