Sprinkler and drip repair from Old Town to Lake Pleasant

Stop the water before anything else. The City of Peoria's guidance for a stuck irrigation valve is to turn off the outdoor water at the backflow device, then repair the faulty valve. Find that shutoff now, before you need it, and keep the area around it clear so the handles can be reached and turned.

Arizona licenses contractors through the Registrar of Contractors. Ask for the ROC licence number in writing, then type it into the public Contractor Search, which shows whether the licence is active, suspended or expired on the day you look, and which classification it covers.

The City of Peoria asks residents to schedule landscape irrigation between 11 p.m. and 7 a.m. That avoids weekday demand peaks, when pressure can drop, and the daytime heat and wind that evaporate spray. It is the city's recommendation rather than a mandatory schedule, and it suits most spray and drip zones.

A backflow preventer is the assembly that stops water in an irrigation system being drawn back into the drinking supply. Many water providers require it to be tested by a certified tester and the result filed with them. A device that fails has to be repaired or replaced and then re-tested.

Peoria's water-saving guidance gives a simple test: when the top two to three inches of soil are dry, it is time to water, which you can check with a screwdriver or soil probe. On a lawn, footprints that stay visible after you walk across it are the same signal. Check before adding minutes.

Every sprinkler on a zone runs for the same length of time, so the heads on that zone have to apply water at the same rate. Mixing head types or nozzle sizes on one zone means part of it is always over-watered by the time the driest part has had enough.

No. The City of Peoria's rebate page says smart controllers do not fix leaks, broken parts or inefficient design. A smart controller adjusts the schedule to the weather, which helps only once the system underneath is working. Repair leaks and broken heads first, then decide whether a new controller is worth it.

A regular timer runs a fixed clock schedule until somebody changes it. A smart controller adjusts run times from weather or soil-moisture data. EPA WaterSense labels the controller models that meet its water-efficiency criteria.

Dry desert soil cannot absorb a lot of water quickly, so a long single run sheds water before it soaks in. Peoria recommends cycle and soak: for example, three 10-minute cycles with 30 minutes between them instead of one 30-minute run. Overspray from heads turned out of line is the other usual cause.

An audit measures how much water lands where, catch cup by catch cup across a zone, and turns that into a run time. The Irrigation Association certifies landscape irrigation auditors for exactly this work; it is a measurement, not an estimate.

More often than most people do. AMWUA advises adjusting schedules at least four times a year, and the City of Peoria recommends adjusting them monthly so plants get what they need as the weather changes. Free monthly reminders are available by texting WHENTOWATER to 1-844-416-1428. Treat these as guidance, then check soil moisture.
