WSP Twin-Tank Water Softener - TT-SKID48STLT

If you need soft water continuously, without breaks when your system regenerates, the WSP Twin-Tank Water Softener - TT-SKID48STLT is designed to keep water soft in your home or building at all times. This twin-tank setup handles hard water without interruption.

The problem

Hard water in your home means you likely see spots on dishes, a scaly buildup on faucets, and possibly a stiff feeling in towels after washing. If you already have a softener, you may notice it stops providing soft water while it regenerates—that period when the system cleans itself and recharges the resin that removes hardness. During that time, hard water runs through your pipes, undoing the benefits you expect.

Why it’s happening

Water softeners work by exchanging hard minerals like calcium and magnesium for sodium or potassium ions, but the resin bed inside eventually fills up and needs to be flushed and recharged—a process called regeneration. Most single-tank softeners must take the system offline during this cycle, which means hard water passes into your home until the process finishes. If your water supply cannot tolerate these interruptions, you experience periods of hard water.

What it’s costing you to leave it

Allowing hard water through during regeneration can build scale inside your pipes and appliances, shortening their effective life. You might use more soap and detergent because hard water reduces cleaning effectiveness. Over time, scale deposits can become harder to remove, leading to more frequent, tougher cleaning and a decline in the performance of water heaters, dishwashers, and faucets.

How this system fixes it

The WSP Twin-Tank Water Softener uses two tanks working in tandem to provide a continuous supply of soft water. While one tank is regenerating, the other is actively softening water. This back-and-forth, or alternating operation, means soft water never stops flowing to your home or building. The system relies on the ion exchange process inside each tank, but by having two tanks, it manages regeneration without interruption to your water supply.

What this system can handle

This twin-tank softener is built around two large 48-inch steel tanks mounted side by side on a sturdy steel skid. It’s designed for situations where a single tank isn’t enough to maintain uninterrupted soft water service, such as larger homes or facilities with continuous water demand. The heavy-duty steel skid keeps tanks level and aligned, reducing strain on plumbing and minimizing vibration. This setup can handle the hard water load steadily, regenerating one tank while the other serves your water, which is a key advantage over single-tank systems.

What you actually get

Included with this system are two 48-inch steel pressure tanks covered by a lifetime warranty, assuring long-term durability. You also get a bypass valve that allows you to isolate the softener for maintenance without cutting off your water supply. Additionally, 10 feet of discharge hose comes with the system for the drain line. The control valve and electronics come with the manufacturer’s own warranty, and the entire system is mounted on a steel skid designed for stability and ease of installation.

Is this the right size for you

This twin-tank setup suits homes or facilities that must have uninterrupted soft water, such as where soft water is essential for equipment or operations that can’t tolerate hardness even briefly. If your water usage is lower or you can accept soft water pauses during regeneration, a single-tank system might suffice. Conversely, if your demand is very high or you want future expansion, this twin-tank system offers a solid foundation for adding capacity.

Living with it

Maintenance involves occasional checks and cleaning of the control valve and ensuring the discharge hose and bypass valve are functioning well. The heavy steel tanks require minimal upkeep due to their lifetime warranty and robust construction. Regeneration cycles happen automatically, so you won’t need to intervene often beyond routine inspections by your plumber. Having the bypass valve included means you can keep water running during service without hassle.

What it won’t do

This system is designed specifically to reduce hardness by ion exchange and maintain continuous soft water during regeneration. It does not reduce other water issues like iron staining, sediment, chlorine taste or odor, or microbial contamination. If your water problem includes these, you’ll need additional or different treatment equipment tailored to those specific challenges.
