WSP 120,000 Grain Twin-Tank Water Softener

Cleaning bathroom fixtures, shower doors, and kitchenware feels endless when hard water’s leaving mineral rings and spots that come back fast. The WSP 120,000 Grain Twin-Tank Water Softener keeps your water soft without interruption, even during regeneration cycles, so surfaces stay cleaner longer and scrubbing lessens.

Where Hard Water Shows Up Day After Day

When hard water runs through your home, it leaves behind stubborn scale and mineral deposits. You see it as cloudy spots on glassware, white or orange rings in sinks and toilet tanks, and a filmy layer on shower doors that needs frequent scrubbing. Towels can feel rough and stiff, and even your coffee or tea may taste off, like it’s been brewed with pool water. Despite regular cleaning, these marks return quickly, especially in areas with continuous water use.

How the Control Head Keeps Your Water Soft Without Breaks

This system’s control head is a metered valve that tracks actual water use to decide precisely when to regenerate the media. Its digital display lets you check the status and adjust settings, while 1.5-inch porting supports higher flow rates for larger or busier homes. Because it's a twin-tank setup, one tank always supplies soft water while the other regenerates. This means you won’t lose soft water during the cleaning cycle — a big advantage for continuous demand.

What the Media Does to Soften Your Water

Inside the tank, high-capacity cation exchange resin targets hardness minerals like calcium and magnesium. These minerals cause scale and deposits, and the resin swaps them out for sodium ions to “soften” your water. The standard mesh size balances effective treatment with good flow, keeping that hardness from reaching your faucets and appliances. This media is designed specifically for hardness reduction, making it effective at improving your water quality.

The Tank Size and What It Means for Your Household

The 16-inch diameter and 65-inch height tank holds about 3.75 cubic feet of media, delivering a softening capacity rated at 120,000 grains. This large volume means the system can handle significant usage before needing regeneration, which helps reduce maintenance frequency. The bigger 1.5-inch ports allow water to flow freely, so water pressure stays steady even under heavy use.

Who Benefits Most from This Twin-Tank System

This setup suits commercial properties, multi-unit residences, or homes with high or continuous water demand—places where soft water is needed around the clock and can’t be interrupted during regeneration. If your household has many bathrooms or water outlets running simultaneously, this system keeps up without strain. For smaller homes or moderate use, a simpler or smaller system might be a better fit, as this unit is designed for tougher, larger-scale needs.

What You Receive When You Choose This System

The system includes the lifetime warranty on the main pressure vessel tank, ensuring long-term durability. The control valve and electronics come with the manufacturer’s warranty terms. You also get a bypass valve at no extra cost, allowing you to isolate the softener for service without shutting off water to your home. Ten feet of discharge hose for the drain line is included as well, so basic installation parts are ready to go.

Sizing is a trade-off, not a target. Go bigger and it regenerates less often and uses less salt per gallon softened; go smaller and you will find the soft water running out before the next cycle. When in doubt, up. Send us your water test if you would like the sizing checked before you order.
