Plumber in Ocotillo Heights, San Tan Valley

EPCOR operates the San Tan district and the water meets drinking water standards. Hardness at 15 to 18 grains per gallon is a mineral content issue, not a safety one. Wanting an RO system for taste and dissolved solids is still a reasonable choice, and it is one we install constantly here.

They do different jobs. The softener protects your plumbing, water heater and appliances from scale but does not improve taste. The RO handles drinking and cooking water. Most homeowners here want both, and installing them at the same time saves a separate trip and some labor.

Be careful with the dramatic in-home demonstration — the version with an electrode that produces a visible reaction works on hard water anywhere and proves nothing about safety. An honest assessment is a hardness reading, a look at your loop, a capacity calculation and real prices. No theatrics required.
