OC WATER PROS LLC designs and installs whole-home filtration, water softeners, reverse osmosis, and well water systems for homeowners across Orange County, California. Locally owned, honestly priced, and matched to your home's actual water.
Many Orange County cities report hardness levels between 12 and 20+ grains per gallon. Over time, those minerals build up inside pipes, water heaters, and appliances.
OC WATER PROS LLC is a locally owned residential water treatment company serving Orange County, California. We are not a national chain and we don't send franchised crews. When you call, the owner answers.
Our owner brings years of hands-on mechanical trades experience to every installation. That background shows up in the details: clean pipe work, careful connections, and systems that are installed to last.
Every recommendation starts with your home's real water data, not a sales script. We recommend the system that fits your home and budget, never simply the most expensive option.

Hardness varies by city and even by neighborhood. Many Orange County areas range from about 12 to 20+ grains per gallon. Your free water report shows the exact numbers for your area.
