Throughout the year your sprinklers can and will take a beating. With soil shifting from temperature and precipitation changes, lawn maintenance and landscaping, pets, and accidental driving.
A regular sprinkler system check schedule can really help you find any issues before they become huge problems.
Make sure you, or your sprinkler professional check that the controller is operating properly with a good schedule, check each zone for at least two minutes a piece and mark any issues, check that the system does not leak any water while not in use, and check to make sure that any added equipment is working properly.
Make any repair immediately before they become costly issues.
