WSP Twin-Tank Water Softener - Fiberglass Tanks

If your home or facility can’t go without soft water even during system regeneration, this twin-tank water softener provides a steady supply. It’s designed for continuous use, handling hard water without interruption, and built to last with fiberglass tanks.

The problem you’re facing

Hard water causes scale buildup on fixtures and inside your water heater. You might notice rings of orange or white in your toilet tank, a film on shower doors, towels that feel rough, or laundry that looks dull and grey. These signs mean minerals like calcium and magnesium are in your water, making everyday cleaning harder and your appliances work tougher.

Why this is happening

Your water picks up minerals as it passes through soil and rocks underground or through old pipes. Hard water isn’t harmful to drink, but those minerals get left behind when water heats or evaporates. The surest way to confirm hard water is a simple water hardness test, which measures the level of dissolved minerals causing these issues.

What it’s costing you to leave it

Scale buildup inside your water heater and pipes shortens their life and reduces efficiency, meaning higher energy bills. You’ll use more soap and detergent to get things clean, and spend extra time scrubbing fixtures and cleaning up stains that become tougher to remove over time. Appliances like dishwashers and washing machines may wear out sooner because they work harder against mineral deposits.

How this system fixes it

This twin-tank water softener uses ion exchange, a process where the hard minerals in your water are swapped out for softer sodium ions. The system holds a large amount of softening material inside the tanks, letting it treat substantial volumes of water. Because there are two tanks working alternately, one keeps softening your water while the other recharges, so you never lose access to soft water.

What this system can handle

The twin-tank setup is built for homes or facilities with heavy, continuous demand for soft water. Each 36-inch fiberglass tank holds a large bed of softening media, which means longer intervals between recharges and higher flow rates without pressure drops. It’s designed to work without pause, so soft water is always flowing, even when one tank is regenerating. This system fits perfectly where a regular single-tank softener would run out mid-cycle or interrupt service.

What you actually get

Included in the system is a pair of corrosion-resistant fiberglass tanks, backed by a lifetime warranty on the tanks themselves. A bypass valve comes standard, allowing you to isolate the system and keep water running to your building during maintenance. You’ll also receive 10 feet of discharge hose for draining the system during regeneration. The control valve and electronics are covered under the manufacturer’s own warranty terms.

Is this the right size for you

This twin-tank system suits homes or buildings that can’t afford any break in softened water supply, especially those with multiple bathrooms, commercial kitchens, or continuous water use throughout the day. If your water use is lighter or you can tolerate a pause during regeneration, a smaller single-tank softener might be sufficient and more cost-effective.

Living with it

Maintaining this system involves periodic refilling of salt for ion exchange and routine checks by your plumber for wear and function. Because of the large media beds and twin-tank design, recharging is less frequent than with smaller units, which saves time. The included bypass valve makes servicing straightforward, so you won’t have to shut off water to your building.

What it won’t do

This water softener helps reduce hardness but doesn’t remove sediment, chlorine, bacteria, or other contaminants. If your water has these issues, you’ll need additional treatment systems like filters or UV purifiers designed for those specific problems.
