Plumbing in Arizona is its own animal
Most of the Valley runs hard water in the 16 to 20 grain range, and that one fact drives a huge share of what we fix. It scales the inside of water heaters, seizes shut-off valves, crusts fixtures, and wears out softeners and reverse-osmosis units years before their time. Nearly every home down here is slab-on-grade, so an aging copper line does not just drip behind a wall, it becomes a slab leak under your floor. Add a monsoon season that overloads drains and yards, and you have a climate that is rough on plumbing.
Up in the high country around Flagstaff the problem flips. There the worry is freeze: exposed lines, hose bibs, and vacant cabin plumbing that splits when the temperature drops. We work both worlds, which is why we keep two real shops instead of pretending one crew covers the whole state. Whatever the job, the approach is the same.
