Water Treatment
in Prescott, AZ
Pure Water, From Source to Tap

Common signs include cloudy or discolored water, scale on faucets and shower heads, soap that won't lather, stained sinks or laundry, dry skin and hair after showering, and a metallic or chlorine taste. The only way to know exactly what's in your water is a certified lab test. The $185 Premium Water Test, which is SimpleLab's Drinking Water Test: Level 1 + Bacteria ordered directly from the lab, identifies hardness plus 53 parameters including arsenic, lead, nitrate, and bacteria.

Aqua Cat Plumbing & Water Treatment is a Prescott-based, owner-operated shop: the person who answers the phone is the plumber with 32 years of Arizona experience who reads your water numbers, sizes the system, and installs it. Prices are published flat rates — softeners from $1,799 installed — with a 2-year labor warranty, a 4.9★ rating, and BBB A+ rating. National franchises serve the area too. What Aqua Cat offers is one accountable person, written pricing, and the owner on site.

It depends on your water source. On City of Prescott water — hard and chlorine-disinfected — the best all-around fix is a combined softener-plus-carbon system like the Tiger 64K Mixed-Bed ($3,399 installed), which removes hardness and chlorine taste in one tank. On a private well, the well decides: hardness, iron, sediment, arsenic, and bacteria vary lot to lot, so we size the system from a certified $185 lab test instead of guessing. A recent Prescott hillside well we tested ran 20 grains per gallon with 451 ppm TDS — a very different fix than a city home.

Published installed flat rates: water softeners from $1,799; the Tiger 64K softener + carbon $3,399; salt-free conditioner $2,750; whole-house carbon filter $1,885; under-sink reverse osmosis from $829; complete well systems $6,475; whole-home RO from $14,999. Every price includes equipment, parts, and labor, and is confirmed in writing before work begins — the flat rate never quietly grows.

Water softening removes hardness minerals — calcium and magnesium — that cause scale, soap scum, and appliance damage. Filtration removes sediment, chlorine, taste-and-odor compounds, and depending on the media, contaminants like iron, arsenic, or PFAS. Most Prescott homes need both. Aqua Cat installs combined softening-plus-filtration systems sized to the lab results from your water test.

Yes — arsenic is naturally elevated across Yavapai County. Peer-reviewed sampling found that more than 40% of private wells in Yavapai and Pinal Counties exceed the EPA 10 ppb arsenic limit, with some Cornville-area wells testing as high as 952 µg/L. Arsenic is colorless, odorless, and tasteless, so a lab test is the only way to know. Whole-house arsenic removal systems bring levels to non-detectable. Learn more about arsenic removal →

Replacement frequency depends on water quality and system type. Sediment pre-filters typically last 6 to 12 months. Carbon filters last 1 to 2 years. Reverse osmosis membranes last 2 to 5 years. Water softener resin lasts 10 to 15 years. Aqua Cat sets a maintenance schedule for every install and offers reminder service so the system never under-performs.

A properly sized system has minimal impact on water pressure — usually a drop of 2 to 5 psi from a static reading. Undersized or clogged systems are a different story. Aqua Cat measures your home's flow rate and pressure before specifying a system, and selects equipment with a service flow rate that matches simultaneous shower, dishwasher, and laundry use without bottlenecking.
