I'm curious as to how long you would keep a warranty valid if the customer calls repeatedly about problems with their sprinklers. I have gotten lots of calls to this client's house to deal with their sprinkler that was installed this spring by us. Most of the problems are that there is a large brown spot in the yard, yet it is getting covered by 4 sprinklers. I've told them numerous times it's not dying because of lack of water but rather there is some kind of disease in the yard. I have refered our chemical guy to this client's house, but they don't want him to come. As I don't own the company, merely work for it, I'm getting tired of all the calls that require me to constantly go over and "fix" whatever problem they have. So..let me hear it. How long would keep it under warranty? Oh..and it's a 5-year warranty.
