Water Softener Systems
Reduce the hard-water minerals behind white spots, crusty faucets, stiff laundry and scale in your water heater. East Valley water is very hard, so this is where most homes start.
Explore serviceValley Water Pros is based in Mesa. Our city's water is hard, and how hard depends on which zone you're in and the time of year. We help Mesa homeowners pick a softener, filter or RO system that fits their part of town.
Mesa blends three sources: Salt and Verde river water from SRP, Colorado River water through the CAP canal, and a small share of groundwater. The mix shifts during the year, which is why hardness can swing.
Average hardness
About 12 gpg in the City Zone, about 16 gpg in the Eastern and Southern Zones (very hard)
