Installing a residential irrigation system seems like a simple way to keep your lawn healthy without the hassle of manual watering, but there’s quite a bit to it, from understanding the flow of water to spray patterns.
From hidden costs to long-term maintenance, homeowners often overlook important details that can affect adequate coverage, performance, efficiency, and overall satisfaction.
Installation Can Affect Your Property More Than You Think
"Something to keep in mind is that an irrigation system is not just placing sprinkler heads into the ground so you can simply water your lawn," noted Heather Todd, brand president for Conserva Irrigation. "Even simple irrigation systems are an investment and a major household project! If not installed properly or efficiently, your system could cost you more in the long run."
Digging trenches for sprinkler lines isn’t as easy as laying pipes underground. The process is disruptive, to say the least. Water pipes often damages existing landscaping, and underground sprinkler systems can even interfere with gas lines and utilities (always call before you dig).
Above ground systems (like drip irrigation systems) require seasonal maintenance and setup, too. In many regions, homeowners must completely disconnect and store the system before frost.
A poorly planned system can also lead to water pooling in the wrong areas. This potentially causes drainage and foundation issues. That’s why it’s important to choose a professional who understands proper system design and placement.
Not All Contractors Are the Same — Know What to Ask
Choosing a licensed irrigation contractor is just as important as selecting the right system. Some irrigation companies cut corners, use low-quality materials, or don’t provide proper follow-up service. Before hiring a sprinkler system installer, Todd noted the importance of asking the following questions:
- Are you insured?
- Are you licensed?
- Do you offer service and maintenance?
- Are you backed by the IA (Irrigation Association)?
- How are your technicians trained or certified?
- Do you have a satisfaction guarantee?
"If the answer is “no” to any of these questions, they may not be the right company for you," she notes. A good contractor will take the time to explain the installation process, customize the system for your lawn’s needs, and provide ongoing support to keep it running efficiently.
It’s Not a Set-It-and-Forget-It System
Many people assume once an irrigation system is installed, it runs itself. While automation is a big advantage, it still requires regular maintenance and adjustments to work properly. Automatic sprinklers can get clogged or knocked out of alignment, and leaks can develop in underground systems without obvious signs. There may be weeks and months where you don't need to irrigate, or stretches of drought when your soil needs more moisture. Seasonal changes always impact the watering schedule, meaning settings should be adjusted throughout the year.
If the system isn’t maintained, you could end up with dry patches from uneven watering, overwatering, or high water bills caused by an undetected leak. That’s why working with a company that offers ongoing service is important. Ask about maintenance plans and whether they provide seasonal system checks before you commit to an installation.
FAQ
How long do in-ground sprinkler systems last?
A well-maintained system can last 10–20 years, but individual components like sprinkler heads or control valve manifolds may need replacement sooner. Regular maintenance and seasonal tune-ups can help extend its lifespan.
Will an irrigation system increase my water bill?
It depends on how it’s designed and used. A properly installed and programmed system can actually reduce water waste, potentially lowering your bill. Smart controllers and efficient sprinkler head types manage both water flow and spray distance to prevent unnecessary watering in the spray arc. Rain sensors and soil sensors also reduce excess water waste.
