- How do I adjust a spray head?
The irrigation spray head will have a nozzle attached with a set spray pattern. While watering, grab the pop-up part of the irrigation head (just below the nozzle) and twist until desired coverage is reached.
- What is a backflow preventer?
The backflow preventer (vacuum breaker) is required by the city for all new irrigation systems. It is typically located directly outside of the home adjacent the water source connects to the irrigation mainline. The backflow preventer prevents water from siphoning back into the house.
- How often should I water?
It is good practice to irrigate turf with 1″ water per week. Watering every other day with rotor zones for about 25 to 35 minutes and spray zones for about 10 to 20 minutes. The best time to water is early morning between 3:00 am to 6:00 am. Soil type and weather conditions can affect watering times. Sandy soil will require longer watering times while clay soil may require multiple run times, cutting watering time in half and running the system twice. July and August will typically have the longest run times in Minnesota.
- What to do in freezing weather when my system hasn’t been winterized yet?
The most important thing to do is cover up the backflow preventer with a towel or blanket, this will help prevent it from freezing.
- What to do in case of a leak?
If the leak only occurs when a zone is running, turn off the time for that zone on the controller. If the system is constantly leaking, go to the backflow preventer and turn the handles perpendicular to the pipe or turn the wheel handles to the right until tight.
