Description
If your home struggles with hard water and you can’t go without soft water even while the system regenerates, this twin-tank water softener from Water Softener Plus (WSP) is designed for you. It keeps soft water flowing continuously and handles a large household’s needs reliably.
The problem
Hard water leaves a film on your shower doors, stains your fixtures with a stubborn residue, and makes your towels stiff after washing. You might notice your coffee tastes off, or that soap doesn’t lather as well as it used to. If you’ve used a softener before, you know how inconvenient it is when the water temporarily returns to hard during regeneration — no soft water for hours at a time.
Why it’s happening
Hard water contains minerals like calcium and magnesium that build up inside your pipes and appliances. Softening happens when those minerals are swapped out for sodium on resin beads inside the system. But when a single-tank softener regenerates, it takes the resin offline for a while, and your water runs hard again. This twin-tank setup uses two tanks that alternate, so one is always delivering soft water while the other is regenerating.
What it’s costing you to leave it
Scale buildup shortens your water heater’s life and clogs faucets and showerheads, making them less efficient. You end up using more soap and detergent to get the same clean feeling. Appliances like dishwashers and washing machines work harder, which means more wear and more energy use. Stains and scale deposits get tougher to remove the longer you wait.
How this system fixes it
This system uses a process called ion exchange, where hard minerals are swapped for softer ones on special resin beads inside the tanks. Because it has two tanks working in rotation, you get soft water all the time — no waiting for regeneration to finish. When one tank is working, the other is cleaning itself, so your water never switches back to hard.
What this system can handle
The WSP Twin-Tank Water Softener is built for large homes or facilities that need a continuous supply of soft water. It uses two high-capacity resin tanks filled with 10% cross-linked cation softening resin — a durable type that handles hard water well. The Fleck 5810 SXT metered control valve measures your actual water use to regenerate only when needed, avoiding wasted salt or water. This system can cope with the demands of multiple bathrooms and plenty of daily water use, regenerating automatically at the right time without interrupting your supply.
What you actually get
This complete system includes the twin high-capacity resin tanks, the Fleck 5810 SXT metered control valve, and the 10% cross-linked cation softening resin inside the tanks. You’ll also receive a bypass valve so you can isolate the system while keeping water running to your home during any service or maintenance. For drainage, 10 feet of discharge hose is included. The pressure vessels carry a lifetime warranty, giving you long-term peace of mind.
Is this the right size for you
This twin-tank system suits large homes or buildings where soft water is essential all day long, such as those with 3 to 6 bathrooms or heavy water use. If your household is smaller or you can manage with a short interruption during regeneration, a single-tank system might be more cost-effective. For very large or commercial applications beyond typical home use, you might need a custom solution.
Living with it
Maintenance mainly involves occasional salt refills and periodic servicing by your plumber. The metered control valve helps keep salt and water use efficient, so running costs stay reasonable. The bypass valve makes servicing easier by letting you isolate the system without shutting off your water supply. Regular checks and salt addition every few weeks or months, depending on your water usage, are all that’s needed to keep it running smoothly.
What it won’t do
This system helps reduce hardness minerals but does not remove other water issues like iron, sulfur odors, bacteria, or sediment. If you face those problems, you’ll need additional or different filtration equipment tailored to those specific concerns.
