Why Soften?

Hard water costs you money

Baja California has some of the hardest water in Mexico — typical Rosarito hardness levels run 200–400 ppm, well above the 120 ppm threshold for “hard” water. Tijuana and Playas de Tijuana share the same source profile, Ensenada homes mix municipal and well water, and the well-water properties out in Valle de Guadalupe routinely test even harder. The result: white scale on fixtures, cloudy spots on glassware, and a water heater that gives up years before it should.

A softener uses ion exchange to remove calcium and magnesium — protecting your plumbing, extending appliance life, and making soap and detergent actually work the way they're supposed to.

Maintenance

How Often Should My Softener Be Serviced?

A softener does not use replaceable filter cartridges, but it does need regular attention. We recommend a full inspection once a year: salt level, brine tank, resin condition, hardness test, and a programming check. Total Home Care includes your annual softener inspection alongside your whole-house and RO maintenance, so every water system in your home is covered under one plan.
