If you have a yard with a drip irrigation system you should get to know this place.
What's the difference between them and Home Depot who sells the same stuff? Good question, I'm glad I asked. Sprinkler World actually has people who know what they're talking about. Sure, if you just want to buy some 1/4" tubing, go to Home Depot but if you actually have questions or if your timer suddenly goes nuts on you or you have no idea why one of the valves is leaking then these guys will explain it all to you.
They actually spent about 20 minutes with me once so I'd understand how to fix something and sold me the required parts for just under $2. Great customer service.
The other beauty is I compared their prices to Home Depot - same price. A no-brainer for sprinkler/drip parts and advice.
