How It Works
Water enters the system and leaves as soft, conditioned water. The softener removes hardness minerals—calcium and magnesium—that cause scale, spots, and dry skin, giving you soft water throughout your Fort Jefferson property.
Why hardness is the problem
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. Ion exchange is the only method that actually takes them out of the water rather than 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.
Holds salt for automatic regeneration, so the resin is recharged and you always have soft water.
Regenerates on demand, not on a clock
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 the property actually uses and recharges the resin at the right moment.
See & Feel the Difference on Garden Key
Softening is one of the few upgrades you notice right away. Showers feel better, glassware comes out clear, and the ring around faucets stops coming back—especially helpful in Fort Jefferson’s marine environment.

The Mr. Pure Water Whole-House Water Softener uses advanced ion-exchange technology to take the calcium and magnesium out of your water 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 the 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 tells you when to top it up. The result is soft, conditioned water at every tap: no scale in the water heater, no spots on the glassware, no film on the shower door, and noticeably less soap and detergent to get the same clean—especially helpful in Fort Jefferson’s tropical maritime, salt-air environment where plumbing and equipment face extra corrosion concerns.
