WSP Twin-Tank Water Softener - Skid

WSP Twin-Tank Water Softener - Skid keeps your home's water soft without interruption, even during regeneration. Designed for heavy, constant water use, it delivers soft water continuously by switching between two large tanks. This system is built to handle high pressure and frequent cycling, ideal for households that can’t afford downtime.

Hard water’s daily impact starts with your morning routine

That first shower of the day leaves a filmy residue on the tiles and makes your towels less fluffy than they used to be. When you pour coffee or tea, you notice a dull taste, and the kettle builds up scale faster than before. The dishwasher door often has mineral spots, and your fixtures show faint rings that need scrubbing more often. These are the signs of hard water—high mineral content that interrupts your day-to-day comfort and chores.

How the control head keeps your water soft without pause

This twin-tank system uses an automatic backwash cycle to lift and rinse the media bed, keeping it fresh and effective. The duplex layout means it always has one tank in service while the other regenerates, so you don’t lose soft water during that process. You can set the system for your water usage, and it handles the rest. This design saves water and salt compared to older or single-tank systems that flush more often or interrupt your supply.

High-capacity resin that targets hardness minerals continuously

Inside each tank is a cation exchange resin—special beads with a natural attraction to hardness minerals like calcium and magnesium. As hard water passes through, these minerals swap places with sodium ions on the beads, softening your water. Because there are two tanks working alternately, the system doesn’t need to pause service when one tank flushes out the collected minerals, ensuring your water stays soft all day long.

Steel tanks built to last and handle demanding conditions

The system fits two 36-inch steel treatment tanks. Their large size means a lot of resin, which supports high flow rates and long periods between regenerations. The steel construction offers strength to withstand high water pressure and frequent cycling, so the tanks resist wear and perform reliably year after year. This setup suits homes where water demand is heavy and never stops.

Who this twin-tank system suits best

This system is tailored for typical single-family homes with demanding water use—think larger households with multiple bathrooms, or homes where you can’t afford to lose soft water even briefly. It’s not for light use or small homes where a single-tank softener would suffice. If your water use is moderate and occasional downtime is acceptable, a smaller system might be more economical.

What you receive with your purchase

The WSP Twin-Tank Water Softener comes complete with a bypass valve included, so you can isolate the system and keep water running to your home during maintenance or repairs. Also included is 10 feet of discharge hose for the drain line. The steel tanks carry a lifetime warranty, protecting the pressure vessel for as long as you own your home. The control valve and electronics have the manufacturer’s warranty according to their terms.
