WSP Twin-Tank Water Softener - Skid

The WSP Twin-Tank Water Softener - Skid from Water Softener Plus is designed for homes or buildings where soft water must be available nonstop, even during system regeneration. Its twin-tank setup keeps softened water flowing without interruption, handling heavy demand with large-capacity steel tanks.

The problem you're dealing with

If your water feels rough on skin, leaves orange or brown rings in your toilet tank, or causes stains on sinks and fixtures, you’re likely dealing with hard water. You might also notice soap not lathering well, shower doors and faucets getting a cloudy film, or your laundry coming out stiff and dull. These everyday frustrations signal minerals like calcium and magnesium in your water.

Why hard water happens

Hard water contains minerals picked up as groundwater moves through soil and rock. The usual culprits are calcium and magnesium, which don’t cause immediate health issues but do interfere with cleaning and wear down appliances. A simple water hardness test, which measures mineral concentration, confirms if your water is hard enough to cause these effects.

What it costs you to leave hard water untreated

Hard water minerals build up inside water heaters, shortening their life and reducing efficiency. You’ll need more soap and detergent to get things clean, which adds up in expense and leaves residues on clothes and dishes. Stubborn scale on plumbing fixtures and inside appliances means more frequent cleaning or earlier replacement. Over time, these costs become noticeable in both money and effort.

How this system helps reduce hard water issues

The WSP Twin-Tank Water Softener uses ion exchange—a process where hard minerals swap places with sodium or potassium ions held in the system’s resin. As water passes through, calcium and magnesium stick to the resin, and softer sodium or potassium ions take their place. This reduces the hardness that causes scale and those other common problems.

What this system can handle

This twin-tank setup is built for continuous, heavy use. While one tank softens water, the other regenerates, so there’s no downtime or return to hard water during the process. Each 36-inch steel tank holds a large media bed, allowing high flow rates and long intervals between regenerations. The rugged steel tanks stand up to high pressure and constant cycling, making this unit suitable for large homes, multi-family buildings, or facilities needing soft water around the clock.

What you actually get

The system includes two durable 36-inch steel treatment tanks on a skid platform set for straightforward installation. You receive a bypass valve at no extra cost, so your plumber can isolate the softener for maintenance without shutting off your water supply. Also included is 10 feet of discharge hose for the drain line. The tanks carry a lifetime warranty on the pressure vessel, while the control valve and electronics are covered by the manufacturer’s standard terms.

Is this the right size for you

This twin-tank water softener suits properties with continuous or very heavy water demand where running out of soft water during regeneration isn’t an option. If your water needs are lighter or intermittent, a smaller single-tank system may be more cost-effective and easier to install. Confirm your daily water use and pressure requirements before choosing this model.

Living with it

Maintenance mainly involves regular regeneration using salt or potassium chloride, which your plumber can set up based on your water hardness and usage. The included bypass valve makes servicing straightforward without interrupting your water supply. Periodic checks on the control valve and occasional replacement of resin over many years keep the system performing well. The effort and cost are reasonable given the system’s capacity and durability.

What it won’t do

This softener reduces hardness minerals but doesn’t remove other common water issues like sediment, chlorine taste or odor, iron staining, or bacteria. If your water has those problems, you’ll need additional filters or treatment systems designed specifically for those concerns.
