WSP Twin-Tank Water Softener - Fiberglass Tanks

Wonder why your skin feels dry and your hair looks dull after showering? It’s probably the hard minerals in your water leaving a residue that soap can’t fully wash away. The WSP Twin-Tank Water Softener with fiberglass tanks helps reduce those minerals continuously, so you get soft water even while one tank regenerates.

Living with Hard Water Without Breaks

Have you noticed your skin feeling tight or itchy after a shower, or your hair that once felt smooth now going dry and brittle? Hard water minerals leave behind a film that soap can’t rinse off easily. It shows up as soap scum on your shower walls, a cloudy film on glass doors, and stiff towels that never seem fluffy. You might also spot orange or brown rings in toilet tanks and sinks. These are all signs your water has minerals like calcium and magnesium that build up inside pipes and appliances too.

The Automatic Control That Keeps Water Soft, Always

This system’s control head runs the whole show automatically. It manages service, backwash, and rinse cycles so you don’t have to think about it. Because it’s a twin-tank, or duplex, setup, it uses one tank to treat your water while the other tank regenerates—that’s the cleaning process that refreshes the media inside. This means you get soft water without interruption, even during regeneration. The control head can also support more complex setups if your needs grow.

What’s Inside the Tanks That Does the Hard Work

Inside each fiberglass tank is a high-capacity cation exchange resin. This special media swaps out hardness minerals in your water for sodium or potassium ions, which don’t cause buildup. Because it has a large media bed, it can handle lots of water between regeneration cycles. That helps keep your water consistently soft, even if you use a lot throughout the day or night.

Large Tanks Built to Last and Handle Heavy Demand

The system uses two 36-inch fiberglass tanks, each holding a large amount of this resin. Fiberglass resists corrosion from water and treatment chemicals better than steel, so the tanks last longer. The size means the system can handle high flow rates and long periods between needing to regenerate, perfect for homes or buildings with continuous water use. You’ll notice fewer interruptions and less frequent maintenance.

Who This System Works Best For

This twin-tank softener suits a typical single-family home with a whole-house water supply, especially if you can’t afford to lose soft water during regeneration. It’s ideal where demand is heavy or continuous, like larger homes or facilities with multiple bathrooms running at once. If your household water use is lower or you don’t mind waiting during regeneration, a smaller single-tank softener may be a better fit.

What Comes With This Purchase

When you order this system, it includes a lifetime warranty on the fiberglass tanks themselves, so the pressure vessels are covered for life. The control valve and electronics have their own manufacturer warranties. A bypass valve is included at no extra cost, letting your plumber isolate the system if it needs servicing while still providing water to your home. You’ll also get 10 feet of discharge hose for the drain line. U.S. shipping is free and included in the price.
