Is it worth if if I start to add irrigation work to my bag of goods. Just repair turn on and turn off. No install for now. Around here their are 3 to 5 companies and they never show up unless it is an install. I am thinking it would be a huge up sell for us. Many clients have systems already and they are always complaining about zero service or help. Next is where can I go get a crash course on irrigation repair. I haven't done any irrigation repairs for 5 years and at the course we just put new heads on and used slip fixes to repair lines. Who has a crash course school that I can learn the ways or am I way off! Let me know guys.
