What’s in Walnut’s water?
The rolling hills of Walnut are served by the Walnut Valley Water District, which relies almost entirely on imported water delivered by the Metropolitan Water District rather than local wells. That imported supply travels hundreds of miles from the Colorado River and Northern California, arriving hard and treated with chloramine to keep it safe over the long journey. Homeowners notice the results as mineral scale on fixtures, spotting on dishes, and a subtle chemical taste in every glass. The hardness also leaves skin and hair feeling dry after a shower. Installing a PurAgain system removes up to 99% of these contaminants, transforming imported water into clean, soft water your family will actually enjoy drinking.
The only way to know exactly what’s in your Walnut water is to test it, and that in-home test is free.

Do you offer free water testing in Walnut?
Yes. A certified Puragain Water technician comes to your Walnut home, tests your water on the spot, and shows you exactly what's in it — at no cost and no obligation.
Is the tap water in Walnut hard?
Walnut, in Los Angeles County, draws on local groundwater basins blended with imported supply, and it runs consistently hard. The high mineral content scales up plumbing, water heaters, and appliances and leaves spots on every surface. A Puragain Water system removes hardness minerals, chlorine, and up to 99% of contaminants.
