Common Sprinkler Problems in the Arizona Desert

The Arizona desert presents a unique set of challenges for irrigation systems. From intense UV radiation to hard water, our environment is tough on equipment.

If you own a home in Phoenix, you will eventually face irrigation issues. Understanding the specific causes of these problems can help you prevent them or catch them early. Here are the most common issues we see in the Valley.

1. Sun Damage (UV Degradation)

The sun is relentless. Plastic components like sprinkler heads, drip tubing, and valve covers become brittle and crack over time due to UV exposure.

Prevention: Use high-quality, UV-resistant materials. Bury drip lines under at least 2-3 inches of granite or mulch to shield them from direct sunlight.

2. Hard Water Buildup (Calcification)

Our water is full of minerals like calcium and magnesium. As water evaporates, it leaves behind white, crusty deposits that can clog drip emitters and seize up spray heads.

Solution: Regular system flushing and using self-cleaning emitters can help. If your heads are stuck, they may need to be replaced. See our repair services.

3. Root Intrusion

Desert trees (Mesquite, Palo Verde, Sissoo) have aggressive root systems that seek out water. They can wrap around pipes and crush them, or grow directly into the lines through tiny cracks.

Sign: A sudden drop in pressure or a wet spot near a large tree often indicates root damage.

4. Critter Damage

Thirsty rabbits, pack rats, and ground squirrels will chew through drip lines to get to the water inside. This is a constant battle in desert landscaping.

Tip: Keep your landscape free of debris where rodents can hide. If damage is frequent, consider upgrading to hard pipe or using protective mesh.

5. Valve Failure

Valves are the heart of the system. Heat and age cause the rubber diaphragms inside to wear out, leading to valves that won't open, won't close, or leak constantly.

If you have a valve issue, our valve repair experts can rebuild or replace it quickly.

Conclusion

Living in the desert requires vigilance. By understanding these common issues, you can keep your irrigation system running smoothly and your landscape looking its best.
