Custom Lawn Sprinklers installed a Hunter Pro C system for me two or three years ago. The guys who installed it did not dig deep enough. As a result, I have had numerous shovels, etc. go through it because just planting my vegetable garden was enough to hit the lines, they were only inches below the ground. When I brought this to their attention, I was told it was not their problem because the family had bought the business from Dieter, Dieter did the lousy work so not their problem. Absolute crap. I stuck with them anyway, a big mistake.
Last year, when they closed my system, they failed to drain the water out of the fertilization system. The person who closed my system did not drain it and then put it in my pool shed. During the winter, the water froze and destroyed the system which is worth about $800. They have refused to even call me back, let alone take responsibility. Terrible company, stay away.
