Sprinkler Head Replacement in Glendale, Arizona

Replacing a sprinkler head in Glendale is often less about the broken part than about the lawn around it. Many yards here have changed since the system went in, and the heads have not caught up.

Yards that changed around the heads

Glendale's ranch-house subdivisions of the 1950s and 1960s, which the city's General Plan highlights, were built around front lawns. Many of those lawns have since been partly converted to gravel. Heads that once watered grass now sit under rock, spray a block wall or water a bed that has its own drip line. In newer neighbourhoods to the north, shrubs planted beside the lawn have grown up and now block the spray. Before replacing a head, ask whether that spot still needs a spray head at all. The right answer may be a cap, a shorter riser, a different arc, or moving that corner onto drip.

Matching the head to the zone

A replacement head should match its neighbours in type, height and spray pattern. Rotors and fixed sprays put down water at very different rates, and one valve feeding both will flood one area while the next stays dry. Set the head at grade, square to the slope, with its arc ending at the edge of the turf. Pointing it a few degrees off can mean a wet sidewalk every morning. A head that sprays the street at the same hour every day is easy for a neighbour to report in GlendaleOne, so after any replacement, watch the zone run once at its scheduled time and adjust the arc before walking away. Keep a spare head and nozzle of the same model; matching is easier when the model is known. Glendale's drought plan counts runoff that travels 250 feet or pools over 200 square feet as water waste, so the aim matters as much as the part.

Misting, pressure and the time of day

Heads that mist, fog or barely rise are not always faulty. The City of Glendale says pressure depends on which of its four pressure zones a home is in and can dip from 6 to 8 a.m. Very high pressure causes misting, and very low pressure leaves pop-ups below grade. Check the zone at its scheduled hour before buying new heads. Pressure-regulating spray bodies can help where pressure runs high.

Nozzles and the city rebate

The City of Glendale's conservation rebates for single-family city water customers include high-efficiency nozzles and WaterSense labeled spray bodies. The terms:

• the irrigation system must be in good working order;
• the parts being replaced must not already be on the WaterSense product list;
• the new parts must be new, not refurbished, and bought on or after January 1, 2023;
• photos of old and new parts, an itemized receipt and a W-9 matching the water account go with an online application, one per fiscal year.

Check the city page for current terms before buying. The head replacement service page covers the general work, and the head pressure guide helps diagnose misting and heads that will not rise. See the rebate guide for the full program.
