Have questions about your sprinkler system? Below are answers to some of the most common questions homeowners ask about sprinkler repair, irrigation systems, backflow testing, sprinkler activation, winterization, drainage, and more. If you don't see your question, contact Clearflow Irrigation and we'll be happy to help.

Why is my water bill suddenly higher?

A sudden increase in your water bill is often a sign of an irrigation problem. Common causes include underground sprinkler leaks, broken sprinkler heads, leaking valves, incorrect controller programming, or sprinkler zones running longer than they should. Sometimes the leak is obvious, while other times it can be hidden underground without creating a noticeable wet spot. At Clearflow Irrigation, we inspect your entire sprinkler system to identify the cause, recommend the most cost-effective repair, and help prevent water waste and future damage.

Why are some areas too wet and others too dry?

Uneven watering is one of the most common sprinkler system problems homeowners experience. It can be caused by clogged or worn sprinkler nozzles, broken sprinkler heads, poor head spacing, incorrect spray patterns, low water pressure, high water pressure, leaking valves, or an irrigation system that isn't properly adjusted. Over time, these issues can create dry spots in some areas while overwatering others, leading to unhealthy grass, higher water bills, and wasted water.

Why does my controller keep resetting or acting weird?

A sprinkler controller that keeps resetting, loses its programming, or behaves unexpectedly can be caused by several issues. Common causes include power outages, electrical surges, a failing backup battery, loose wiring, moisture inside the controller, or an aging controller that's beginning to fail. Incorrect programming or damaged wiring connected to the irrigation system can also cause zones to run at the wrong times or not operate at all.

How quickly can you come out?

We understand that many sprinkler system problems can't wait, especially during the growing season. We do our best to schedule appointments as quickly as possible, and in many cases, we're able to provide service within a day or two depending on our schedule and the time of year.

Why is one zone not turning on?

If only one sprinkler zone isn't turning on, the problem is usually isolated to that zone rather than the entire irrigation system. Common causes include a faulty sprinkler valve, a bad solenoid, damaged valve wiring, a controller programming issue, low water pressure, or a broken underground irrigation pipe. In some cases, tree roots, landscaping work, or normal wear and tear can also damage irrigation components and prevent a zone from operating properly.

Why is my system running when it’s raining?

If your sprinkler system is running during or after rainfall, it could be caused by several factors. Your rain sensor may not be installed, may not be working properly, or may need to dry out before allowing the system to adjust its schedule. If you have a smart Wi-Fi irrigation controller, the weather settings may not be configured correctly, or the controller may not be connected to the internet. In some cases, the controller may simply be following its programmed watering schedule because no rain sensor or weather adjustment is active.

How long should I water my lawn?

The ideal watering schedule depends on your grass type, soil conditions, weather, and sprinkler system. Most lawns benefit from deeper, less frequent watering rather than watering every day. We can help program your irrigation controller for maximum efficiency while reducing water waste.

Do smart irrigation controllers save water?

Yes. Smart irrigation controllers adjust watering schedules based on weather conditions, seasonal changes, and rainfall. Many homeowners reduce unnecessary watering while maintaining a healthier lawn. We install and program smart Wi-Fi controllers that make managing your irrigation system simple.

How long does a sprinkler system last?

A professionally installed sprinkler system can last 20 years or more with proper maintenance. Individual components such as sprinkler heads, valves, controllers, and backflow preventers may need occasional repairs or replacement as they wear over time.

Do you guarantee your work?

Yes. We stand behind the quality of our workmanship and use quality parts designed for long-term performance. If you have questions about your repair or installation after the job is complete, we're happy to help and make sure everything is operating as expected.

Can you add sprinkler heads to an existing system?

Yes. We can add, relocate, or adjust sprinkler heads to improve coverage, eliminate dry spots, and make your irrigation system more efficient. Before adding heads, we evaluate your water pressure and flow to ensure your system can support the additional demand.
