What contaminants are in Phoenix tap water?

Phoenix tap water from the Salt River Project and Central Arizona Project typically contains chlorine (disinfectant), total dissolved solids of 464 to 716 mg/L (City of Phoenix 2025 Water Quality Report), and hardness of 172 to 302 mg/L (10 to 17.6 grains per gallon) in the same report. Free water testing from Purest Water Solutions identifies your exact contaminant levels and recommends the right filtration or softener system for your home.

Do I need a water softener in Las Vegas?

Yes. Las Vegas water from Lake Mead is among the hardest in the United States, averaging 278 to 415 mg/L total hardness. Hard water accelerates water heater corrosion, leaves scale on fixtures, and shortens appliance life. A whole-home water softener typically pays for itself within 2 to 3 years through reduced energy costs and appliance replacement savings.

Does Purest Water Solutions offer free water testing?

Yes. Purest Water Solutions provides free in-home water testing for homeowners in California, Phoenix, and Nevada. A technician tests for hardness, chlorine, iron, total dissolved solids, and pH at your tap. There is no obligation to purchase, and results are explained clearly before any system is recommended.

What is a combo 2-in-1 water system?

A combo system combines a water filter and water softener into a single unit. It filters out contaminants like chlorine and sediment while also removing hard water minerals like calcium and magnesium, giving you clean and soft water from one system.

Is a combo system as effective as separate units?

Modern combo systems are highly effective and deliver excellent results for most homes. For extremely hard water or specific contamination issues, separate dedicated units may be recommended. We test your water to determine the best solution.

How much space does a combo system require?

Combo systems take up roughly half the floor space of two separate units. Most fit comfortably in a garage, utility closet, or near the main water line entry point.

What maintenance is required?

Combo systems require periodic salt refills for the softening function and occasional filter media replacement. We offer maintenance plans that handle everything for you on a regular schedule.

Is a combo system as good as separate units?

For most homes, yes. Modern combo systems deliver excellent filtration and softening performance in a single unit. However, homes with extremely hard water (25+ GPG) or specific contamination concerns may benefit from dedicated separate systems. Our free water test helps determine which is right for you.

How does a combo system compare to just a water softener?

A water softener only removes hardness minerals. A combo system also filters out chlorine, sediment, and other contaminants -- giving you both soft and clean water. If you are considering a softener, it is worth exploring combo systems for more comprehensive treatment at a modest price increase.

What kind of maintenance does a combo system need?

Combo systems require periodic salt refills (similar to a standalone softener) and filter media replacement on a schedule determined by your water usage and quality. Most homeowners refill salt monthly and replace media every 3-5 years. We offer maintenance plans that handle everything.

Compare the pieces

A water softener only removes hardness minerals, and filtration handles chlorine, sediment, and other contaminants. A combo system does both, and for the purest drinking water many homeowners also add a reverse osmosis system at their kitchen tap.
