SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

I can't tell you what to use unless you tell how big your yard is, Generally, Rotors are for bigger, more wider areas, such as your backyard. They generally have a radius of 15'-35'. Sprays on the otherhand, only have a radius of about 15'. You use them for smaller areas, such as the strip between the road and sidewalk. The radius on a sprinkler really depends on your GPM and PSI. For brands, I always install Hunter and Rainbird. You choose what's best for you, you should choose which sprinklers, valves, and clock is best for YOU.

Then I would use the PGP's for the 57'x 130, but for the 15'x 130, you could either use sprays, or Hunter PGM's
