I had David’s Irrigation install a completely new sprinkler system in 2013(having never had a system) and it is still going strong. They did a professional installation and have also serviced my system as well. David and Juan were just out yesterday(because I couldn’t figure something out) and made sure my system was operating properly. It was… I just got confused! After having the system for a couple of years, and monitoring my water usage, I’ve seen better results(with my lawns, trees and water bill) than just regular watering. I highly recommend you at least get an estimate from David’s Irrigation when considering a system. I’m very happy with my system and the service after the sale has been top notch!
