Sprinkler heads

What they do

Sprinkler heads can be set to water quarter-, half-, or full-circle areas. Some heads can even water square or rectangular-shaped areas. Pop-up sprinkler heads are the most popular types of heads for home lawns, although others are available.

What to look for

Pop-up heads should have a height of at least 4 inches so that they would reach above high mowed turf. Pop-up sprayers should output water at 25 - 30 psi (pounds per square inch). Poor coverage can result if some heads have a high-pressure output while others have low pressure. Pop-up sprayers with a pressure reducing device installed into the unit are available. Try to use "matched precipitation rate" heads where quarter-, half-, and full-heads all put out the same amount of water per unit area leading to more uniform coverage.
