A good irrigation system needs minimal maintenance. Minimal maintenance usually consists of the back-flow inspection (if required by the county), spring turn-ons, and winterization appointments. A spring turn-on will take care of all the adjustments to ensure you are getting the right coverage.
Winterization is a vital part of keeping your irrigation working as it should. In order to prevent freeze damage, the irrigation system should be winterized by the first freeze of the winter season, usually early December. Keeping up with maintenance can prevent a lot of problems in the future. An irrigation system is a great investment for your home, so it makes sense to take care of it.
