How It Works
Hard water from the main supply enters the system and leaves as soft, conditioned water. The softener removes the hardness minerals—calcium and magnesium—that cause scale, spots, and dry skin, giving you soft, luxurious water throughout your Marathon Shores home.
Why hard water is a problem in Marathon Shores
Calcium and magnesium are dissolved rock. They don’t filter out the way sediment does—they come out of solution as scale on anything warm or wet: the inside of your water heater, the shower glass, the dishwasher element, the faucet aerators. In Marathon Shores and across the Florida Keys, ion exchange is the method that actually removes hardness minerals instead of just changing how they behave.
Sits on top of the tank, monitors usage, and regenerates automatically when the resin needs it.
Ion-exchange resin attracts and removes hardness minerals as water flows through the bed.
Holds salt for automatic regeneration, keeping resin recharged so you have soft water on demand.
Regenerates on demand—no clock-based cycling
Timer-based softeners regenerate whether you needed it or not—wasting salt and water on a quiet week, and running out mid-cycle on a busy one. This valve meters what your Marathon Shores home actually uses and recharges the resin at the right moment.
See & Feel the Difference in the Florida Keys
Softening is one of the few upgrades you notice without looking for it. Showers feel better, glassware comes out clear, and the ring around the faucets stops coming back—welcome relief from hard water in Marathon Shores.

The Mr. Pure Water Whole-House Water Softener uses advanced ion-exchange technology to remove the calcium and magnesium that make Marathon Shores water hard—before it reaches a single fixture. A high-capacity resin tank (up to 42,000 grains) does the work, while an electronic control valve meters how much water your household actually uses and regenerates on demand rather than on a timer. The built-in brine cabinet keeps the resin recharged, and a low-salt indicator lets you know when to top it up. The result is soft, conditioned water at every tap across your Florida Keys home: less scale in the water heater, fewer spots on glassware, less film on shower doors, and noticeably less soap and detergent to get the same clean.
