Prescott & Yavapai County’s
Well Water Plumber

Yes — Prescott city water is moderately hard at 4.3 to 7.6 grains per gallon - the City's own published figure - while Yavapai County wells commonly run 12 to 32+ grains per gallon (ADEQ's basin studies average about 12 gpg across the Prescott Active Management Area and 18 gpg in the Agua Fria basin, with some wells far higher), well above the 7 gpg threshold the U.S. Geological Survey classifies as "hard." That's why scale forms quickly on faucets, soap won't lather, and water heaters fail years early without softening. A whole-house water softener is the standard fix; the free hardness check with every estimate, or the $185 lab test, tells you exactly where your home stands.

Prescott city water is treated and tested by the City (its 2025 water quality report lists arsenic from 2.6 to 10 ppb across its seven wells). A private well is yours to test: nobody tests it for you. Across Yavapai County, more than 40% of water samples in a peer-reviewed study exceeded the EPA arsenic limit of 10 ppb (Jones et al., 2020), county wells commonly run 12 to 32+ grains hard, and iron, manganese and sulfur show up in the Chino and Verde valleys. The $185 Premium Water Test tells you exactly what you have, and Neil reads the report with you at no charge.

Two flat rates: $829 installed for The Kitten (4-stage) or $999 installed for The Ocelot (5-stage alkaline remineralizing). Both include the system, a dedicated faucet, the storage tank, faucet hole drilling in your counter or sink, haul-away of packaging and a 2-year Aqua Cat labor warranty on top of the manufacturer's warranty. See the reverse osmosis page for what each stage does.

Water softener installation in Prescott starts at $1,799 (existing loop); the most popular 64K Mixed-Bed is $3,399, fully installed. Cost depends on system capacity (grain rating), salt-based vs. salt-free, and whether existing pre-plumbing is in place. Softener installs are currently unavailable — not being scheduled at the moment — and the prices are shown for reference. See our water softener installation page for sizing and what each package includes.

SimpleLab’s Drinking Water Test: Level 1 + Bacteria covers 53 parameters, including arsenic, lead, uranium, nitrate, hardness, iron and total coliform bacteria. You order the kit directly from the lab for $185, fill the bottles at your tap and ship them back; results come as a plain-English report. Aqua Cat reads the report with you at no charge and tells you what, if anything, needs fixing. See water testing.

The only way to know is a certified lab test — arsenic is colorless, odorless, and tasteless. In Yavapai and Pinal Counties, peer-reviewed sampling found over 40% of water samples exceed the EPA's 10 ppb arsenic limit, with some Cornville-area wells testing up to 952 µg/L. The $185 Premium Water Test - SimpleLab's Drinking Water Test: Level 1 + Bacteria, ordered directly from the lab - covers arsenic among its 53 parameters. If you're on a private well, test annually. See our arsenic removal page and the Yavapai County arsenic guide.
