WSP 120,000 Grain Twin-Tank Water Softener - Meter

For homes or buildings that can't pause soft water, especially during water softener regeneration, the WSP 120,000 Grain Twin-Tank Water Softener - Meter offers a continuous solution. It handles hard water problems with a high-capacity twin-tank system designed for uninterrupted soft water supply.

When the First Shower Shows Your Hard Water Trouble

Have you noticed that the moment you step into the shower first thing in the morning, there’s a film on the glass door or the water feels less slippery than it should? That’s hard water at work. It leaves behind scale spots on your fixtures, stubborn buildup on taps and appliances, and can make towels feel stiff even after washing. This isn’t a one-off; it affects your daily routines and adds extra effort to cleaning and laundry.

How the Control Head Keeps Soft Water Flowing Without a Break

The heart of this system is the metered control head that tracks your actual water use. It decides the right time to clean and refresh the softening media based on how much water you use, not just a clock. This control head has smart Bluetooth connectivity, letting you monitor and make adjustments from your phone. It remembers your settings through power outages, so your softener keeps working smoothly. Plus, its 1.5-inch ports allow higher water flow to handle larger homes or buildings without slowing down.

Why This Media Handles Hard Water So Well

Inside the tanks is a special high-capacity cation exchange resin designed to target hardness minerals—mostly calcium and magnesium—that cause scale buildup. Water passes through this resin, which swaps these minerals for sodium or potassium ions, softening the water. Below the resin sits a graded gravel underbed that ensures water flows evenly through the resin, making the softening process more efficient and consistent, even under heavy use.

The Tank Size and What It Means for Your Water Use

This system features two 14-inch by 65-inch tanks, each packed with about 3.75 cubic feet of resin. The twin-tank setup means one tank is softening your water at all times while the other is regenerating and cleaning itself. With a total softening capacity of around 120,000 grains before needing regeneration, the system supports continuous soft water supply without interruption, making it ideal for busy homes or commercial settings.

Who Should Choose This System and When to Consider Other Sizes

The WSP 120,000 Grain Twin-Tank Water Softener is best suited for large homes, multi-unit buildings, or commercial sites where many outlets run simultaneously, and soft water must be available at all times—even during regeneration cycles. If your household or facility has lower water demand or fewer bathrooms, a smaller system may be more cost-effective and easier to maintain. Conversely, if you have exceptionally high use or very hard water, sizing up might be necessary, and we can help confirm that.

What You Receive and How to Get Started

This system includes a lifetime warranty on the tanks themselves—the pressure vessels are built to last. The control valve and electronics come with the manufacturer's standard warranty. A bypass valve is included, so you can isolate the system for maintenance while still having water flow 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. Once you order, our team will help confirm your system sizing to ensure it fits your specific water needs and flow rates.

Who this size is right for

At 120,000 grains of capacity this suits a commercial or multi-unit site - around continuous high demand with many outlets.

Those figures assume average hardness and normal use. If your water is unusually hard, if you have iron as well as hardness, or if the house simply runs more water than most, take the next size up - an oversized softener regenerates less often, while an undersized one runs out of soft water between cycles. Send us your water test if you would like the sizing checked before you order.
