All I can say is you guys seem to have really small yards. My yard is 17,000 sqft. Subtract the house, driveway, sidewalk, and landscaping, and I’ve still got a good 14k sqft of lawn to water. I don’t see any way I’m going to be able to drive a system of this type from my two spigots.

On the flip side, my quote from a professional for a 10-zone, 42-head system is less than $3,500. Is your estimate of $3,000 for a 5,000 sqft front and back yard still accurate?
