WSP Twin-Tank Water Softener - Ski

Your water test shows hardness minerals well above recommended levels, leaving a dry film on dishes, soap scum in the shower, and stiff towels after washing. These everyday annoyances add up, especially when you need soft water all the time, even during system maintenance or regeneration cycles.

Ongoing Hard Water Challenges Without a Break

Hard water means the minerals in your supply—mainly calcium and magnesium—build up scale inside pipes, fixtures, and appliances. You notice it as an orange ring in your toilet tank, spots on glassware, or a grimy film on shower doors. Soap doesn’t lather well, leaving you using more detergent than usual, and laundry can feel rough or fade prematurely. If you’ve ever had a softener that went offline during regeneration, you know the difference: hard water rushing back until the cycle finishes, which can be disruptive if you rely on continuous soft water.

How the Automatic Backwash Control Keeps Water Soft 24/7

This system’s control head runs an automatic backwash cycle. It lifts and rinses the resin bed inside the tank to clear the hardness minerals caught there. Because the WSP Twin-Tank Water Softener uses two tanks working alternately, one tank can regenerate while the other is in service. This means soft water keeps flowing without interruption, a key advantage for households or facilities that cannot afford hard water at any time. You can set the system timing to fit your household’s water use, making sure it only regenerates when needed to save salt and water.

Resin Media Designed for High-Capacity Hardness Removal

Inside each tank is a high-capacity cation exchange resin, the part that actually softens your water by swapping hardness minerals for sodium or potassium ions. This resin is specially selected to handle high volumes, so it maintains performance even when working hard. The tanks themselves are fiberglass, a corrosion-resistant material that holds up over time and keeps the media contained securely. The result is consistent soft water without downtime.

Durable Fiberglass Tanks Sized to Fit Your Home

The system supports 21-inch and 24-inch fiberglass treatment tanks, common sizes for softening systems in single-family homes. These tanks hold enough resin to treat your whole-house water supply effectively, allowing the twin-tank setup to alternate between service and regeneration. That means the system is both physically robust and intelligently designed for continuous operation, reducing wear and extending the life of your water softener.

Ideal for Single-Family Homes Needing Continuous Soft Water

This twin-tank setup is suited to typical single-family homes where soft water cannot be interrupted during regeneration cycles. If you have a household that experiences high water use or multiple bathrooms running at once, this system can keep up without letting hard water through. For smaller households with more modest water use, a single-tank softener might be enough, while much larger properties or commercial facilities might need a more specialized system tailored to their flow rate and consumption. Confirming your water use and hardness level with the WSP team ensures you get the right fit.

What Comes With the System

You receive a rugged skid assembly designed for 21" and 24" fiberglass tanks, a bypass valve included at no extra charge so you can isolate the softener for servicing without shutting off water to your home, and 10 feet of discharge hose for the drain line. The tanks themselves carry a lifetime warranty on their pressure vessels. The control valve and electronics come with the manufacturer’s warranty, which covers issues according to their terms.
