FAQ about service and maintenance:

Q: How do I start up my system?


A: Click here for Written Start-up Instructions.

Q: My system won't run. What could be wrong?

A: First, check the controller to make sure that is working properly. Some clocks have a battery back up, so it may appear that the controller is on. If a controller is working on battery back up it will not activate the system. Plug a hair dryer or similar appliance to check the power to the outlet. Also, if it has rained recently, check the Rain Sensor override. A second thing to check is to make sure the water supply to the irrigation system has not been shut down at any point. Check the main shut off valve in the basement and at the back flow point there is usually a valve or two that can be closed and stop water flow to the irrigation lines. If everything checks out fine, call our office and schedule a service call.

Q: My system won't shut off. What do I do?

A: First, check the clock program to make sure it hasn't been changed. Next turn the clock off using the dial (don't unplug the clock, it may loose its program). If the system won't shut off from the clock, you will need to shut the water supply to the whole system off. For some reason the valve will not shut down allowing constant water flow to the zone. Call our office and we can schedule a technician to make the repair.

Q: How often and how much should I water?

A: Following are guidelines from the Minnesota Nursery and Landscape Association. However, you will want to verify any watering restrictions for your community. With so many cities going to odd/even restrictions, it may be necessary to set your controller to water on an every other day schedule.

When To Water: Watering is best for lawns in the pre dawn hours. Between midnight and 8am are usually calm; evaporation is low, and it is the time many cities with restrictions will allow you to water.

How Much Water Is Needed: In the Spring and Fall, set your rotor zones for 20-30 minutes and spray zones for 5-10 minutes. This is approximately half an inch per week. During the summer, set your rotor zones for 30 to 45 minutes and spray zones for 10 to 15 minutes. In periods of hot dry weather set your rotor zones for an hour and spray zones for 20 minutes. This will be approximately an inch and a half per week. When it rains, rely on your rain sensor or Smart Controller system. If you don't have either one, you'll need to manually shut your system off for a few days.

Q: I have a rain sensor, it is raining and the sprinklers are running. Why?

A: It may be that it has not rained enough to trigger the sensor. If this is not the case, check to make sure the receiver is not set on ‘bypass' and that the controller is not set on ‘rain bypass'. Check the receiver signal light - is it flashing green? This can be due to a temporary weak signal or the battery is low and needs to be replaced.

Q: Does Green Acres offer service agreements for maintenance?

A: Yes we do! Prepaid Service Agreements can be purchased for your irrigation system prior to start-ups any given year. We offer a variety of plans options, Gold, Silver, Bronze, & Flex; choose one that fits you. To learn more about our plans click here, Prepaid Service Agreement Plans.

A: This depends on the size and complexity of the job, typically only one day for an average size home!

Q: What happens to my existing lawn during installation?

A: We install the trenchless way! We use special equipment to install your brand new sprinkler system with very little disruption to your property. We simply make a clean cut in the turf, while pulling pipe in directly following the cut and then tamp the cut turf back into place. The installers are careful to remove turf in one piece for digging the holes for valves and heads. The turf can easily be reinstalled around the valves and heads and tamped back into place. Within a very short time the turf will heal and you will not see any evidence to the turf having been disturbed.

Q: Can I use well water or water from a lake to supply my irrigation system?

A: YES! We specialize in installing lake pumps for systems drawing water from a lake. Well-derived water supplies do not present a problem either. Simply talk to your estimator about these water sources.

Q: I have several flowerbeds; will I still need to hand water these?

A: No! There are several options for watering your flowerbeds. Be sure to discuss these needs with your estimator.

A: No! We specialize in irrigating these specialty items. Be sure to discuss these needs with your estimator.

A: Green Acres Sprinkler Company has a full service, service department. Our service department schedules all appointments for spring start up, maintenance and repair, and fall winterization. In the spring and fall we notify you by mail to get spring and fall service scheduled. We also offer full service prepaid service agreement plans.

Q: Will the irrigation system still run when it's raining?

A: No, all Green Acres Sprinkler Company systems come with rain sensors! The sensor monitors the rainfall and will temporarily stop the automatic watering cycles when appropriate then allows it to reactivate when the rain sensor is dry.
