WSP Whole House Reverse Osmosis System - Commercial, C-Series

In the first week after installation, you’ll notice a clear difference in how your water tastes and smells. The sharp, metallic hint and lingering off-flavors in your drinking or processing water will start to fade, leaving fresher, cleaner water for drinking, cooking, and equipment use.

What You’re Dealing With in Your Water Today

Your water probably carries a range of dissolved solids—tiny particles like salts, minerals, and chemicals that you don’t see but definitely taste. You might notice a chalky or bitter flavor in your coffee, an odd smell when you pour a glass, or that water spots and mineral residues build up on glassware or appliances. These dissolved solids also include specific contaminants like lead, arsenic, fluoride, and nitrates that affect taste and water quality.

How the Control Head Makes It Work Efficiently

The heart of this system is its metered control head, which tracks exactly how much water passes through rather than running on a timer. This means it only regenerates—the process that refreshes the system’s filtering ability—when needed, saving water and salt. With its 1.25-inch porting, it supports higher flow rates, so it keeps up even in places with heavy, continuous water use without slowing down.

What’s Inside: The Media Doing the Work

The system’s filtering depends on a thin-film composite reverse osmosis membrane that targets dissolved solids, salts, and a range of contaminants. Alongside that, a high-capacity cation exchange resin softens the water by reducing hardness minerals like calcium and magnesium. This combo helps improve taste and protect equipment from scale build-up, making the water better both for drinking and for commercial or multi-unit use.

The Tank and Capacity You Can Rely On

The system includes a rugged vessel designed to hold the filtration media and membrane. While the exact tank size is tailored to your specific setup, the system is built to handle large volumes reliably. Depending on the version, it can produce from roughly 3,200 to 15,000 gallons of treated water per day, with capacities for softening ranging between 120,000 and 210,000 grains. This means you get consistent water quality even under heavy, continuous demand.

Who Should Consider This System—and Who Should Look Elsewhere

This system suits commercial sites or multi-unit buildings with many water outlets and ongoing high water use. It’s designed for locations where water quality affects taste and process reliability, as well as areas where dissolved solids and certain contaminants need to be significantly reduced. If your water needs are smaller or you have lower flow demands—such as a typical single-family home—you might want to look at smaller, less complex options that match that scale better.

What Comes Next

Every WSP Whole House Reverse Osmosis System is configured specifically for your water problem and needs. We do not sell these units off the shelf because proper sizing and setup are crucial for performance. To get started, contact the WSP team with details about your water issues and ZIP code. We’ll provide expert sizing advice and a personalized quote tailored to your exact situation. Reliable, well-sized equipment means better water quality and long-term value.

Who this size is right for

At 120,000 grains of capacity this suits a commercial or multi-unit site - around continuous high demand with many outlets.

Those capacities assume a household using roughly 75 gallons per person per day at average hardness. Long showers, a big laundry load or a well with iron in it all push the real figure up, so size for your worst week rather than your average one. Send us your water test if you would like the sizing checked before you order.
