Purchasing and installing a sprinkler system is a wonderful home improvement investment. Following a few simple tips for using and maintaining your system will help you avoid unnecessary sprinkler repair bills. Your very best defense against costly, major repairs is to watch carefully for possible damage to your system. Check for any leakage when you turn the valve or valves on, so that a small break does not become a massive leak later on. Be sure to replace your batteries in the irrigation system, if your sprinkler uses them. Check each sprinkler head, making sure they are not leaky and that they are watering the lawn accurately. Keep the area around your sprinkler heads trim. In the early spring, be sure that all dangers of frost have ended before using your system.
