The Sprinkler World businesses are in several places around the Valley. I have been doing DIY sprinkler repairs and winter lawn (perennial rye) for the last 15 years. You're greeted upon entering the store, and receive personalized service from very knowledgeable staff. The prices BEAT ALL the big box hardware stores. Today Gus helped me with the problem I was having with my system, and even showed me a tool ($5.47) that would save me time in the repair. Another staff member (Kevin) who was at the Mesa store today, even recognized me from the Glendale store where I used to get supplies. If you want to save big money and get great service go to Sprinkler World. Prepare to be amazed!
