I found David Edie on Yelp and the two reviews convinced me to give him a call. Am I glad I made that call. I purchased a house where the previous owner had installed the in-ground irrigation system himself. It was not to code and the valves were a leaky mess. There were also drip lines that were blowing off the manifold due to excess water pressure. David, along with his crew, replace all the valves, added backflow preventers to bring the system up to code and place an inline pressure reducer to reduce water pressure to the drip lines that kept blowing off. The job was professionally done and they also cleaned up the yard where they had to dig. I was completely impressed and satisfied and have no hesitation in recommending David and his company for your irrigation needs.
