On one of commercial accounts for the past month someone has been breaking the irrigation in at least 3 different spots, usually the day before I arrive to mow. I have gone to visit the property at different times to try to catch them but no luck. I am assuming that someone is after the account and is trying to make me look bad. I have talked with the owner to inform him of the situation and he is going to let me know if any recent offers for service have been made. Any thing else I can do?
