Proper Irrigation Wiring

We had to re-wire an entire irrigation system put in by a builder that used improper wiring for the whole system. Fortunately, it was a large irrigation system so it wasn't expensive for the new homeowner. I've seen many things in my years but telephone wire for irrigation wire is a first. I'm sure there was a logic but we believe at Millenium Irrigation that you do things the right way not the half way.
