WSP Twin-Tank Water Softener - Steel Tanks

Wonder why your first shower of the day never feels quite right, and the dishwasher door fogs up with mineral spots? Hard water is to blame. The WSP Twin-Tank Water Softener with steel tanks keeps your water soft without interruption, even when one tank is busy regenerating.

When Hard Water Interrupts Your Day

That morning shower leaves a film on your skin and shower door, or your towels come out stiff and scratchy after washing. The dishwasher door fogs up with cloudy spots, and your coffee sometimes tastes flat, almost like you’re drinking pool water. These are signs of hard water—water loaded with minerals like calcium and magnesium that leave scale behind. You see it as the orange rings in the toilet tank or the buildup on faucets, and you scrub it away, only to find it returns.

How the Control Head Keeps Soft Water Flowing Without Downtime

The WSP Twin-Tank system uses an automatic control head to manage the water-softening cycles for you. It handles the switching between the two tanks, ensuring that one tank is always treating water while the other regenerates—flushing out the minerals it has collected. You set the timing or volume parameters, and the control head does the rest, moving through service, backwash, and rinse cycles automatically. This means there’s no need for you to turn off your water or go without soft water during regeneration, unlike single-tank systems.

The Media Inside: How Hardness Minerals Are Reduced

Inside each tank is a high-capacity cation exchange resin. This resin targets hardness minerals in your water—mostly calcium and magnesium—that cause scale and spotting. As water passes through the resin bed, the minerals swap places with sodium or potassium ions attached to the resin, reducing the hardness in your water. Because the resin has a large capacity and operates in two tanks alternately, it works continuously without downtime.

The Steel Tanks and Their Capacity to Handle Heavy Use

The system includes two 30-inch steel treatment tanks. These tanks hold large beds of resin, giving the system the ability to treat high volumes of water before regeneration is needed. The steel build ensures it can handle higher water pressures and frequent cycling without wear, built for demanding household or light commercial use. This setup is designed to meet around-the-clock or heavy water demand without missing a beat.

Who Will Benefit Most from This Twin-Tank Setup?

This system suits a typical single-family home with a whole-house water supply and heavy water use. If your household runs multiple showers, washing machines, and appliances simultaneously, or you simply can’t go without soft water at any moment—such as in multi-bathroom homes or small commercial facilities—this twin-tank softener is the right fit. For smaller households or lighter water use, a single-tank system might be more economical and simpler.

What Comes With Your WSP Twin-Tank Water Softener

You receive the twin 30-inch steel tanks fitted with high-capacity cation exchange resin and the automatic control head that manages the cycles. A bypass valve is included at no extra cost, allowing you or your plumber to isolate the system for servicing without shutting off water to the rest of the home. Also included is 10 feet of discharge hose for the drain line installation. The steel tanks themselves come with a lifetime warranty, while the control valve and electronics have the manufacturer’s own warranty terms.
