About this Sun City irrigation website
Irrigation help written for Sun City yards, from lake lots to shared-wall patio homes.
Written for how Sun City is watered
Sun City has no city water department. Its water comes from EPCOR Water Arizona's Sun City Water District, pumped from groundwater that is hard and untreated for hardness. This site explains sprinkler, drip, valve, controller and backflow work with that in mind, for homes built from 1960 onward.
A dry corner on a fairway lot, a seeping valve beside a shared wall and a drip line choked with scale are different problems. Start with what you can see, read the guide that matches it, and describe the zone and the symptom when you request an estimate.

Find the fault before adding minutes
When one bed wilts while water runs down the gutter, a longer schedule rarely fixes it. Heads, emitters, valves, lines and the controller have to work as one system to put water where the roots are.
Many Sun City systems are as old as the houses, and the water leaves scale in small openings. Explore repair and installation for the way your yard is planted today, whether it backs onto a lake, a fairway or a neighbour's wall.
What this work involves
Trace the symptom
Note the zone, when the water appears and what the controller is set to, so the cause can be found before parts are changed.
Agree the scope
Ask whether an adjustment, a repair or a new layout suits the property before any work is agreed.
