Frequently Asked Questions About Sprinkler & Irrigation Systems

Homeowners across Grosse Pointe and nearby east-side communities often have questions about sprinkler systems, irrigation repairs, seasonal maintenance, and water efficiency. Below are answers to the most common questions we hear from customers every week.

General Sprinkler System Questions

1. How do I know if my sprinkler system needs repair?

Common signs include dry patches, leaking heads, uneven watering, low pressure, or zones that won’t turn on. If your water bill suddenly increases, that can also indicate an underground leak.

2. Why is one sprinkler zone not working but others are?

This is usually caused by a faulty valve, bad solenoid, wiring issue, or controller problem. A professional inspection can quickly pinpoint the cause.

3. Is it better to repair or replace a sprinkler system?

Most systems can be repaired rather than replaced. We typically recommend replacement only when piping, valves, and heads are all failing or the system is severely outdated.

4. How long does a sprinkler system last?

With proper maintenance, most irrigation systems last 15–25 years. Individual components like heads and valves may need replacement sooner.

5. How often should my sprinkler system be serviced?

At minimum, systems should be checked during spring start-up and fall winterization. Mid-season inspections help catch issues early.

Sprinkler Repair & Troubleshooting

6. What causes low water pressure in sprinklers?

Low pressure can result from leaks, broken pipes, clogged heads, partially closed valves, or municipal supply issues.

7. Why are my sprinkler heads leaking when the system is off?

This usually indicates a leaking valve or debris preventing the valve from sealing properly.

8. Can tree roots damage sprinkler lines?

Yes. Tree roots can crush, shift, or puncture underground irrigation lines over time, especially older PVC piping.

9. Are sprinkler leaks expensive if ignored?

Yes. Small leaks can waste thousands of gallons of water, increase bills, and cause lawn and foundation damage if left unaddressed.

10. Can you fix sprinklers without digging up the whole yard?

In most cases, yes. Experienced technicians locate and repair issues with minimal digging and disruption.

Seasonal Irrigation Questions

11. When should I turn my sprinkler system on in Michigan?

Most systems are activated between late April and mid-May, depending on frost risk and weather conditions.

12. What happens during a spring start-up?

We slowly pressurize the system, inspect valves and heads, check coverage, adjust spray patterns, and repair any winter damage.

13. When should sprinklers be winterized in Michigan?

Systems should be winterized before the first hard freeze, typically between late September and October.

14. What happens if I skip winterization?

Water left in pipes can freeze, expand, and crack lines, valves, and backflow devices—leading to costly repairs.

15. Do you use compressed air for winterization?

Yes. Professional winterization uses regulated compressed air to safely clear all water from the system.

Sprinkler Heads & Valves

16. How often do sprinkler heads need replacement?

Most heads last 5–10 years depending on water quality, usage, and lawn equipment damage.

17. Are all sprinkler heads the same?

No. Different heads are designed for spray, rotary, drip, and high-efficiency applications. Using the correct head improves coverage and water efficiency.

18. What causes sprinkler valves to fail?

Debris, electrical issues, aging seals, freezing, and normal wear are common causes of valve failure.

19. Can valves be repaired instead of replaced?

Often yes. Diaphragms, solenoids, and seals can sometimes be repaired depending on valve condition.

20. Where are sprinkler valves usually located?

Valves are typically housed in underground valve boxes near the foundation or in landscaped areas.

Sprinkler Timers & Smart Controllers

21. Should I upgrade to a smart sprinkler controller?

Smart controllers adjust watering based on weather, saving water and improving lawn health.

22. Can a new controller reduce my water bill?

Yes. Many homeowners see noticeable reductions by preventing overwatering.

23. Do smart controllers work with existing systems?

Most modern smart timers are compatible with standard residential irrigation systems.

24. What causes sprinkler timers to stop working?

Electrical surges, aging components, wiring issues, or water damage can cause controller failure.

25. Can you program my sprinkler timer for me?

Yes. We set schedules based on lawn type, sun exposure, and local watering guidelines.

Water Usage & Efficiency

26. How long should I water my lawn?

Most lawns need about 1–1.5 inches of water per week, delivered in deeper, less frequent cycles.

27. Is it better to water in the morning or evening?

Early morning is best to reduce evaporation and prevent fungal growth.

28. Can overwatering damage my lawn?

Yes. Overwatering can cause shallow roots, disease, runoff, and wasted water.

29. Does irrigation increase home value?

A well-maintained irrigation system improves curb appeal and can increase property value.

30. Do irrigation systems work with lake pumps?

Yes. Systems using lake pumps require specialized pressure management and filtration.
