How to Upgrade to a Smart Irrigation System | Ask This Old House
Evaluating Your Current Irrigation System
Before diving into upgrades, it’s smart to take a close look at your current irrigation setup. Understanding what works and what doesn’t allows you to pinpoint trouble spots and focus on changes that will make the biggest difference – for both your lawn and your wallet.
Some irrigation problems are easy to spot. For instance, if your water bill has been climbing for no clear reason, you might be dealing with leaks or inefficient settings. Uneven watering is another common issue – dry patches in some areas and soggy spots in others can leave your lawn looking patchy, no matter how much fertilizer you use.
Keep an eye on your sprinkler heads. Signs like water pooling around the base, broken or malfunctioning heads, or sprinklers that don’t rotate properly suggest leaks or installation problems that waste water and can harm your lawn’s roots. Other red flags include inconsistent water pressure, strange noises during operation, or timers and controllers that don’t keep schedules on track. These issues can leave parts of your lawn thirsty, especially during hotter months.
"Efficient irrigation isn’t just good for landscaping; it’s a responsibility. By conserving water and using resources wisely, you contribute to a sustainable future while saving costs" [8].
Older systems often need longer cycles just to maintain coverage [2] [3]. If you’re constantly tweaking run times or dealing with frequent breakdowns, it may be time to consider an upgrade.
How to Test Water Distribution
After evaluating your system, testing its water distribution can highlight specific performance issues. A simple yet effective way to do this is through a catch can test, which shows how evenly your sprinkler zones distribute water.
Start with a visual check. Turn on each zone and look for obvious problems like broken sprinklers, heads that fail to pop up, clogged nozzles, or water spraying in the wrong direction [5]. Then, gather 10–24 identical containers (like small cans or cups) and set them up in a grid pattern across a sprinkler zone. Space them 5–8 feet apart for fixed spray heads and 10–20 feet apart for rotary heads [5].
Run the sprinklers for exactly 10 minutes, then measure the water collected in each container [6] [7]. Compare the amounts – large differences indicate uneven watering. To calculate distribution uniformity, take the average of the lowest 25% of your readings, divide it by the overall average, and multiply by 100 to get a percentage [5].
Professional audits can go a step further, using specialized tools to measure pressure and flow. Ideally, nozzles should operate within 15% of the manufacturer’s recommended pressure, with pressure variation staying below 20% of the system’s design pressure [4].
This testing process can help you figure out if small fixes – like cleaning nozzles or adjusting sprinkler angles – will do the trick, or if bigger changes, such as upgrading old sprinkler heads, are needed to improve your lawn’s health and conserve water effectively.
Upgrading Your Irrigation System
Once you’ve evaluated your irrigation system, it’s time to focus on upgrades that can make a real difference. Modernizing key components can cut water usage by 20% to 50% while improving efficiency and keeping your lawn in top shape [12].
The three upgrades to prioritize are smart controllers, efficient sprinkler heads, and drip irrigation zones. These enhancements ensure your system distributes water effectively and supports healthier landscaping.
Installing Smart Controllers
Smart controllers take the guesswork out of watering by using real-time weather and soil data to adjust schedules automatically. Unlike traditional fixed timers, these controllers respond dynamically to conditions.
- Weather-based controllers connect to local weather stations and adjust watering based on factors like temperature, humidity, wind, and rainfall. For instance, if rain is in the forecast, the system delays watering. During hot, dry periods, it increases watering frequency to protect your lawn.
- Soil moisture sensor controllers go a step further by monitoring moisture levels directly in the root zone. These systems have been shown to reduce irrigation by up to 72% during droughts, with an overall water savings of 34% [13].
Smart controllers typically range from $250 to $900 for standard models, while professional-grade options can cost between $900 and $2,500 [13]. Many homeowners notice their water bills drop by as much as 50% [10]. For example, a study on St. Augustine turfgrass demonstrated a 43% reduction in summer irrigation without sacrificing grass quality [13].
Hiring an irrigation professional for installation ensures the system is tailored to your landscape’s specific needs [11]. Plus, most smart controllers come with smartphone apps, so you can monitor and adjust settings from anywhere.
Upgrading Sprinkler Heads and Nozzles
Modern sprinkler heads are designed to deliver water more evenly and efficiently than older models. Choosing the right type depends on your system’s water pressure, lawn size, and coverage needs.
- Spray heads are best for systems operating at 20–30 PSI and work well for small to medium lawns [15]. They have no moving parts, making them reliable and low-maintenance, though their higher water delivery rate can lead to runoff on slopes.
- Rotary heads require higher pressure (above 30 PSI) and are ideal for medium to large lawns [15]. Their slower application rate is perfect for slopes and slow-draining soils, helping to minimize runoff.
- Pressure-regulating heads maintain consistent pressure, saving up to one gallon of water per minute and cutting water bills by about 30% [9]. Proper spacing and coverage adjustments can further reduce water use by 10% to 30% [9]. Grouping zones by sprinkler type ensures maximum efficiency [15].
Adding Drip Irrigation Zones
Drip irrigation is the perfect complement to smart controllers and upgraded sprinkler heads, delivering water directly to plant roots with minimal waste. This method virtually eliminates runoff and evaporation.
- Surface drip systems are laid above ground and work well for flower beds, vegetable gardens, and areas around trees and shrubs.
- Subsurface drip systems run underground and are better for permanent plantings like established trees and perennial beds [16].
When planning drip zones, consider your landscape’s topography. On slopes, align drip lines with the natural contour to prevent water from rushing downhill and to ensure even distribution [14]. Additionally, keep main drip line runs under 200 feet per zone to maintain proper pressure [14].
Drip systems require dedicated zones because of their lower flow rates [15]. This setup allows for longer watering cycles for drip zones while keeping lawn sprinklers on shorter, more frequent schedules.
The investment in drip irrigation pays off by significantly reducing water waste and promoting healthier plants. By delivering water precisely where it’s needed, these systems help prevent overwatering, reduce plant stress, and preserve essential soil nutrients.
Water Conservation and Efficient Lawn Care
Once you’ve upgraded your irrigation system, it’s time to focus on water conservation techniques to keep your lawn thriving while cutting down on waste. Did you know that up to 50% of outdoor water use is lost to evaporation, wind, or inefficient irrigation methods? [18] Tools like soil moisture sensors and cycle-soak irrigation can make sure every drop of water counts, delivering it precisely where and when it’s needed. These techniques work hand-in-hand with your system upgrades, fine-tuning water usage for maximum efficiency.
Soil Moisture Sensors and Weather-Based Adjustments
Soil moisture sensors are game-changers when it comes to preventing over-watering. Unlike old-school irrigation controllers that water on a fixed schedule, these sensors measure the actual moisture in the root zone and adjust watering based on real-time conditions [17]. For instance, WaterSense-labeled sensors can help a typical household save over 15,000 gallons of water each year. On a larger scale, widespread adoption of these sensors could save an astounding 390 billion gallons annually [17].
For the best results, install these sensors directly in the root zone – fully buried in the soil and kept away from metal objects to ensure accurate readings [20]. Pairing them with weather-based controllers takes efficiency a step further. These controllers use local weather data to adjust watering schedules, potentially cutting water use by up to 30% [21].
Real-world examples showcase the impact of these technologies. For instance, almond growers in California achieved 20–30% water savings by using soil moisture sensors, while a Nebraska corn farmer slashed irrigation by 40% – saving nearly 55 million gallons annually – all without compromising crop yields. Closer to home, a Phoenix homeowner reduced water use by 45% simply by installing moisture sensors [22].
"This sensor beats any weather station setup by far. It truly is a water ‘thermostat’ in your yard", – Charles F., a verified Amazon purchaser of the Rain Bird SMRT-Y Soil Moisture Sensor Kit [19].
If you’re considering adding sensors to your system, they come in a range of options. Basic models are available for under $50, while more advanced setups for larger properties can cost up to $300. For extensive areas, you might need a network of sensors and data loggers.
Cycle-Soak Irrigation Techniques
Cycle-soak irrigation is another smart way to optimize water use. This approach works by dividing watering into shorter cycles with breaks in between, allowing the soil to absorb water more effectively. It’s especially helpful for clay soils or sloped areas, where water tends to run off rather than soak in [23].
"If you are running a sprinkler zone for 14 minutes, the ground likely can’t absorb all that water at once, so the last couple of minutes of that run time is a waste of water", explains Lyle Fair, a landscape professional with the Associated Landscape Contractors of Colorado [23].
Here’s how it works: instead of running a sprinkler zone continuously, split the total watering time into multiple sessions with about an hour between each. For example, if your zone typically runs for 14 minutes, you might break that into two 7-minute cycles. This method not only conserves water but also encourages deeper root growth, reduces puddling, prevents soil erosion, and improves nutrient absorption [24].
To get started, monitor your lawn for signs of runoff or puddling and adjust the watering schedule as needed [23]. Use a soil probe to check that water is reaching 6–8 inches into the ground. If you have a modern smart irrigation controller, you can program it to handle cycle-soak schedules automatically, making the process even easier.
Since outdoor watering accounts for about 40% of total household water use [23], combining soil moisture sensors with cycle-soak techniques can make a big difference. These methods not only help conserve water but also keep your lawn lush and healthy while reducing your environmental footprint.

Seasonal Maintenance for Irrigation Systems
Keeping your irrigation system in top shape throughout the year requires regular seasonal maintenance. Each season brings its own set of challenges, from inspecting for freeze damage in spring to making efficiency tweaks in summer and protecting the system during winter. By staying on top of these tasks, you can ensure your system operates smoothly, prevent costly repairs, and make the most of any recent upgrades.
Spring Start-Up and Inspection
Spring is the time to wake up your irrigation system after its winter hibernation. Before turning it on, confirm that the soil is frost-free to a depth of 12 inches [26]. When you’re ready, open the main water valve slowly – this prevents pressure surges that could damage fittings or dislodge sprinkler heads [25]. Once water is flowing, manually test each zone for leaks and check that all sprinklers are covering the intended areas.
Inspect sprinkler heads for cracks, misalignment, or other damage that might have occurred during the winter. Pay special attention to the backflow preventer, a critical component that shields your household water supply from contamination [26]. Clear any debris, such as leaves or dirt, from nozzles to avoid uneven watering. Finally, adjust your controller settings to match spring’s watering needs – winter settings won’t cut it [25][26].
Summer Adjustments for Peak Usage
Summer’s heat and higher evaporation rates call for tweaks to your watering strategy. To minimize water loss, schedule irrigation between 4:00 AM and 9:00 AM – this can reduce evaporation by up to 30% [27]. Water deeply but less frequently, aiming for 2–3 days per week, and let the soil dry slightly between sessions. This encourages stronger root growth [27]. If temperatures climb above 70°F, increase water usage by 10% for every 10°F rise [27].
Use tools like a screwdriver or moisture meter to check soil dampness 6–8 inches deep before watering. Regularly inspect your system for issues – a single broken sprinkler head can waste up to 25 gallons per minute [27]. Adjust heads to avoid spraying sidewalks or driveways, and skip a watering cycle if you receive at least an inch of rain [27]. Mowing your lawn to about 3 inches helps retain moisture and promotes deeper roots [28]. For even greater efficiency, smart controllers that adjust based on weather conditions can cut water use by 15–30% compared to traditional timers [27]. As summer winds down, start preparing for winterization.
Winterization and System Shutdown
Winterizing your irrigation system is essential to protect it from freeze damage. Water left in pipes, valves, or fittings can expand as it freezes, leading to costly repairs [29]. Before freezing temperatures set in, drain the backflow device and any water between the shut-off valve and the backflow device. Then, choose one of the following methods to clear the system:
- Manual Drain Method: Shut off the water supply, open all manual drain valves at pipe ends and low points, and raise sprinkler heads with check valves to release any trapped water [29].
- Automatic Drain Method: For systems with automatic drain valves, turn off the water supply, briefly run a sprinkler to relieve pressure, and let the automatic drains empty the pipes [29].
- Blow-Out Method: Use compressed air to push water out through the sprinkler heads. Keep the air pressure below 80 PSI for PVC piping and 50 PSI for polyethylene piping to avoid damage [29][30]. Start with the zone farthest from the compressor and work your way through the system. Always wear ANSI-approved eye protection and stay clear of system components while using compressed air [30].
Additional steps include insulating above-ground PVC pipes and removing flow sensors before starting the process [30][31]. Leave the isolation valves on the backflow device partially open (at a 45° angle) and open the test cocks to prevent pressure buildup [30]. If you’re unsure about any part of the winterization process, hiring a professional is a smart move – it’s far cheaper than dealing with freeze-related damages later [29].
