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

MP Rotators

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.
