WSP 150,000 Grain Twin-Tank Water Softener

If your home or building needs soft water all the time, even during the system’s cleaning cycle, this twin-tank water softener with 150,000 grains capacity helps reduce hard water’s effects without interruption. It’s built to keep soft water flowing continuously.

The problem you’re living with

Hard water leaves a mineral build-up that shows up as spots on dishes, a crusty ring inside your toilet tank, and a white film on shower doors and faucets. Towels can feel rough or stiff after drying, and your soap just doesn’t lather well. Over time, your water heater and appliances might struggle under the strain of scale, and you might have noticed more frequent repairs or replacements.

Why this is happening

Your water contains dissolved minerals, mainly calcium and magnesium, that cause hardness. When hard water is heated or left standing, these minerals settle out as scale. You can confirm hard water by testing the water’s hardness using a simple test kit available from hardware stores or online. If you have trouble going without soft water even briefly—such as during the softener’s cleaning cycle—then your household or building needs a system designed to deliver soft water nonstop.

What it’s costing you to leave it

Hard water scale gradually builds inside pipes and water heaters, reducing their efficiency and shortening their lifespan. You’ll use more soap and detergent because hard water stops them from working fully. That can mean stiffer laundry, duller dishes, and more time scrubbing away mineral deposits around faucets and tubs. Appliances like dishwashers and coffee makers may need more maintenance or fail sooner. All these add up in time, effort, and replacement costs.

How this system fixes it

This twin-tank water softener works by exchanging the hardness minerals in your water for sodium ions. It does this with a material called resin inside the tanks, which traps calcium and magnesium and replaces them with sodium, which doesn’t cause scale. Because it has two tanks, when one is cleaning itself—a process called regeneration—the other keeps softening your water without interruption. This means no hard water at any tap, at any time.

What this system can handle

The WSP 150,000 Grain Twin-Tank Water Softener is designed for homes and facilities that need a lot of soft water continuously. With a high capacity of 150,000 grains, it handles heavy mineral loads and large water demands. Its twin tanks alternate so there’s always one working while the other regenerates. It’s built to run smoothly under significant use, making it a step up from smaller softeners that can’t keep water soft during regeneration. The system’s control valve and app-based monitoring help you track usage and adjust settings easily.

What you actually get

The system includes dual mineral tanks with high-capacity resin and commercial distributors, a commercial brine tank with a reliable brine valve and air check, and a 1-1/2" twin-tank control valve for steady operation. A bypass valve is included so you can isolate the system during maintenance without cutting off water to your home or building. You’ll also get 10 feet of discharge hose for the drain line. The mineral tanks have a lifetime warranty on the pressure vessels, ensuring long-term reliability. Control valve and electronics carry the manufacturer’s standard warranty. Plus, a 9-volt battery backup keeps the meter working during power outages (battery not included).

Is this the right size for you?

This twin-tank system suits homes or facilities with heavy water use and a need for uninterrupted soft water. If you have a smaller household or can manage without soft water during regeneration cycles, a smaller single-tank softener might be enough. Conversely, if your water demand is extremely high or you require a larger commercial setup, you might need to size up beyond this model. We help you determine the right fit based on your water hardness and daily water use.

Living with it

Maintenance mainly involves periodic refilling of salt in the brine tank and occasional cleaning of the brine valve and resin tanks. How often the system regenerates depends on your water use and hardness but typically ranges from every few days to weekly. The included bypass valve makes servicing straightforward without interrupting your water supply. Routine checks and salt refills are simple tasks that keep the system running efficiently.

What it won’t do

This system is designed to reduce hardness minerals but does not address other water issues like iron staining, sulfur odor, sediment, or pathogens. If your water has distinct smells, tastes, or visible sediment, you’ll need additional treatment such as iron filters, carbon filters, or disinfection systems to handle those specific concerns.
