Frequently Asked Questions
What is the purpose of the Backflow Assembly and why must it be tested annually?
The backflow assembly prevents contaminated irrigation water from being siphoned back into the clean drinking water supply. The Clean Water Act passed by Congress requires local governments to reasonably ensure that the drinking water supplied to their residents remain safe & clean. The annual backflow test is one step that helps the local governments ensure that the drinking water supply is safe & clean.
What do I do if my controller shows no display?
Check to see if you have power going to the controller. If not, check circuit breakers & GFI outlets in your home to see if they have been tripped. If you have power, but no display, unplug controller for 2 minutes then plug back in. If still no display, see if there is a reset button on your controller - hold for 10 seconds. Still no display? Controller may have gone bad.
Do drainage systems require maintenance?
Yes. Periodic maintenance such as cleaning catch basins, checking outlets, and flushing lines helps ensure proper performance.
Why do my lights turn off randomly at night?
Possible causes include:
- Overloaded transformer
- Timer or photocell malfunction
- Loose wiring connections
A professional inspection ensures safe and reliable operation.
How often should I run my system?
Individual circumstances will vary, however, the Co-op Extension recommends watering more deeply, less often. A general rule is 2 - 3 times per week instead of every day.
Where does the water drain to?
Drainage systems discharge water to approved locations such as:
- Pop-up emitters
- Natural drainage areas
- Swales
- Street or approved municipal outlets (where permitted)
All systems are designed to follow local codes and site conditions.
I want to run my system three times per week. How long should each zone run?
Individual circumstances will vary, but as a general rule, depending on the season, spray heads should run between 5 - 15 minutes, rotors should run 15 - 30 minutes, and drip lines should run 30 minutes to 1 hour.
Why do my lights turn on during the day?
This is usually related to:
- A photocell that is shaded, dirty, or failing
- Timer settings that need adjustment
Cleaning or repositioning the photocell often solves the problem.
What is the best time of day to water?
Early morning is best. Watering during evening times or overnight will make the lawn more susceptible to fungus.
Why are my lights flickering?
Flickering is commonly due to:
- Loose connections
- Moisture in wire splices
- A failing bulb
- Transformer issues
- Voltage issue
This should be addressed promptly to avoid further damage.
