Fleck water softeners, built to order

We use Fleck valves from Pentair Water Solutions and build each water softener to order, matched to your water after a free test at your home. Our softeners have filtration built in; most don't. The result is a system sized for your household, your hardness, and the other issues in your water, then professionally installed by the same team that tested it.

After install we test again, so you can see the difference: nearly eliminated spotting on dishes and shower glass, softer-feeling skin and hair, and less scale on fixtures and inside your water heater.

Every softener we install includes a lifetime limited tank warranty.

A salt-free water conditioner is also available when a salt-based softener is not the right fit, including in River Islands and west Lathrop, where salt-based softeners may be restricted.

Other systems we build to order

Besides softeners, we also build filters to order around Fleck valves, matched to what your water actually needs:

• Whole-house carbon filters for chlorine taste and odor
• Iron and sulfur filters, and sediment filtration, especially for well water
• Well water treatment when several issues show up together

We have various options. The free water test tells us which ones fit your home.

Professional installation, same team start to finish

We don't just drop off equipment. The same local team tests your water, builds the system, installs it, and comes back if you ever need service. Tested before, tested after. No-pressure estimate. That's the way we work on every job.

Financing

Financing is available, including 0% for 21 months on approved credit (OAC). See terms (opens in a new tab) A no-pressure water softening estimate follows the free test. See financing terms or call Sales (209) 645-1151.

Already own a Fleck system?

We also service and repair existing Fleck water softeners and filters, including older units and common valve families. For service on a system you already own, call the office at (209) 523-5921, or see our water softener repair page.

Where we install Fleck systems

We install and service these systems in Modesto, Ripon, Salida, Manteca, Tracy, Lathrop, Riverbank, Oakdale, Escalon and the surrounding Central Valley. See all areas we serve. If you live in River Islands or west Lathrop, a salt-based softener may be restricted (Lathrop Municipal Code Chapter 13.05). A salt-free water conditioner is often the better fit there, and we can confirm that on a free water test.
