Patterson’s Very Hard Water: What a Water Softener Changes at Home

Patterson has some of the hardest city water we treat, and you see it on the shower glass, on the faucets and in the water heater. Here’s what a properly sized softener changes. Clear glasses straight out of the dishwasher. Soap and shampoo that lather and rinse clean. Towels that come out soft instead of crunchy. Faucets and shower glass that don’t crust over a few weeks after you clean them. That’s what a water softener changes in a Patterson home, and families notice it the first week.

There’s more you don’t see. Softened water nearly eliminates spotting, and soap and detergent go further. Most important, hard water scale stops building up inside your water heater and appliances, which helps them run better and last longer.

The numbers back that up. The city’s 2025 report puts average hardness at 402 ppm (parts per million), with a range of 323 to 517 ppm. [City of Patterson 2025 Consumer Confidence Report] It’s all groundwater, so there’s no softer surface supply blending it down. If you moved here from the Bay Area, the water was probably the first surprise: white crust on the faucets, cloudy glasses, dry skin and a water heater that starts popping early.

With water this hard, sizing matters. An undersized softener runs out of capacity fast and regenerates constantly, wasting salt and water. We size the resin tank to your household and the hardness at your tap, then set the valve to regenerate only when it needs to. Our softeners are built with NSF-certified components and come with a lifetime limited tank warranty.

Prefer no salt? Ask about saltless. A saltless conditioner reduces scale buildup with no salt bags and no brine tank. With water as hard as Patterson’s, most families choose a softener for the soft-water feel and fewer spots, but we’ll show you both at your free test so you can decide.

One thing a softener doesn’t do is treat chromium-6. Patterson is also known for chromium-6, which occurs naturally in its groundwater, and the city is working under a compliance plan. [City of Patterson Chromium-6 page] For drinking and cooking water, under-sink reverse osmosis can reduce chromium-6. Our chromium-6 guide for Patterson homeowners explains it clearly.
