Smart and Wi-Fi Irrigation Controllers in Glendale, Arizona

A smart controller is one of the irrigation upgrades the City of Glendale will help pay for, which makes the rules of that rebate the first local detail to get right.

What the Glendale rebate asks for

The city's conservation rebate for single-family city water customers covers WaterSense labeled smart irrigation controllers. The conditions on the city's rebate page include:

• the home must have an irrigation system in good working order;
• the controller being replaced must not already be on the current WaterSense product list;
• the new controller must be new, not refurbished, and bought on or after January 1, 2023, and new construction does not qualify;
• the application is online, with photos of the old and new controllers showing make and model, an itemized receipt, and a W-9 whose name and address match the Glendale water account;
• one rebate per fiscal year, July 1 to June 30, first-come, first-served, with a possible inspection afterwards.

Dollar limits are set on the city page and change, so check it before buying. Homes in the county islands between 75th Avenue and El Mirage Road may not be on city water, and only city water customers qualify.

Installing on an older Glendale system

Most swaps reuse the valve wires already in the ground. In a ranch-house neighbourhood where the system is decades old, it pays to test every station on the old timer first. A station that never worked will not start working on a new controller, and a failing wire splice in a valve box is a common culprit. Check the Wi-Fi signal at the mounting spot as well. A garage wall on the far side of the house is a frequent dead zone, and a controller that cannot reach the weather data falls back to a basic schedule.

Setting it up for Glendale conditions

The app's defaults are guesses. Replace them with what is on each station: turf on spray, shrubs on drip, a citrus tree on its own line. Set start times before 6 a.m., because the city says pressure can dip from 6 to 8 a.m. Let the weather skip work during the monsoon, from June 15 to September 30, when about half the region's yearly rain falls. On downtown lots that take urban flood irrigation, schedule a skip around each delivery day. EPA WaterSense estimates a labeled controller can save a home up to 15,000 gallons a year compared with a clock timer.

Flow sensors and leak alerts

Many smart controllers can pair with a flow sensor, and the city's rebate list covers flow sensors with leak detection as a separate item. A flow sensor watches for water moving when no station should be running, the usual sign of a broken pipe or a stuck valve, and can shut the system down before the water reaches the street. Rain sensors are on the same list.

If the old controller is acting up, controller repair in Glendale may be the better first step.
