Water Quality & Treatment

Water softeners, reverse osmosis, and whole-house filtration for Arizona homes.

Treating hard water in the Phoenix area

Water throughout the Phoenix Metro tends to run hard, which leaves mineral buildup on fixtures, inside water heaters, and on glassware and dishes over time. A water softener addresses hardness by exchanging minerals in the water, while a reverse osmosis system targets drinking water quality at a specific tap, and whole house filtration addresses broader water quality concerns like chlorine taste or sediment. These systems solve different problems, and water testing is the starting point for figuring out which one, or which combination, fits a given home.

Testing results are explained in plain terms before any system is recommended, since hardness levels and other water characteristics vary by specific location even within the same neighborhood. Installation projects come with a free written estimate, and repair visits have a $120 diagnostic, waived when you go ahead with the repair. Iron Horse Advantage includes a plumbing safety inspection and standard water heater flush, not a separate filter-change membership.

Finding the right system

The pages below cover softener installation, reverse osmosis systems, whole house filtration, water testing and analysis, membership plans, warranties, and financing options, including 0% promotional plans for qualifying, approved credit. Each page explains what the system does and who it typically fits. Call the Tempe shop at 1917 E 5th St to schedule water testing or ask which option makes sense for a specific water quality concern.

Financing details are included below for homeowners considering a larger system such as a whole house filtration setup alongside a softener.
