Why It's Important to Inspect the Exterior Parts of Your Irrigation System
When it comes to keeping your irrigation system running smoothly, many people focus on the timers, valves, and sprinklers — but what about the exterior parts?
Over time, outdoor components like piping, fittings, and backflow preventers are exposed to harsh conditions: heat, moisture, UV rays, and even rust.
Neglecting these critical exterior parts can lead to bigger, costlier problems down the road.
Here’s why inspecting and maintaining the outside of your irrigation system is just as important as what’s underground.
The Hidden Danger of Rust and Corrosion
Recently, we came across a galvanized part on a backflow preventer that had rusted through and started leaking.
Galvanized materials — while initially durable — are highly vulnerable to corrosion over time, especially when constantly exposed to water and the elements.
Rust weakens the metal, causing leaks that:
Waste hundreds (or thousands) of gallons of water
Create pressure issues across the system
Lead to property damage if leaks go unnoticed
When we identified the problem, we upgraded the backflow part to copper piping — a much better material for Tucson's environment — to prevent future rusting and extend the system's life.
Why Copper Is a Smarter Choice
Copper piping offers significant advantages over galvanized parts:
Resistant to rust and corrosion
More durable in outdoor conditions
Longer lifespan compared to steel or iron
Better suited for Tucson’s extreme temperatures
Upgrading to copper early can prevent unexpected failures and expensive emergency repairs later on.
Signs Your Exterior Irrigation Parts Need Inspection
Not sure if your system needs attention? Here are some warning signs to watch for:
Visible rust on exposed pipes or fittings
Dripping or pooling water near backflow preventers
Fluctuating water pressure across your irrigation zones
Unexplained increase in water bills
Obvious cracks, dents, or discoloration on metal parts
If you notice any of these, it's time to schedule a professional inspection.
How Often Should You Inspect?
We recommend at least one full inspection per year, especially before Tucson’s high-demand summer months.
Early detection of rust, wear, or other damage saves you water, money, and stress.
If your system uses older materials like galvanized steel, you may want to consider proactive upgrades to copper or other rust-resistant alternatives.

Your irrigation system is a big investment in your property’s health and beauty.
Don’t let exterior wear and tear undo all your hard work.
