WSP Control Valve (WSP-CV-3900)

WSP Control Valve (WSP-CV-3900) is the key component that runs the backwash and regeneration cycles of your water softener or filter. It tracks your actual water use, controls rinsing, and keeps your system operating efficiently with a clear digital display for easy monitoring and setup.

What Your Running Water Is Costing You

Every day, your water system works quietly in the background. But without precise control, scale builds up inside your water heater, causing it to use more energy and fail sooner. Your appliances wear down faster, and you end up using more soap and detergent because the water isn’t properly treated. It’s the kind of slow, ongoing cost that’s hard to notice but adds up over the years in repairs, replacements, and extra cleaning.

How This Control Valve Keeps Your System on Track

The control valve is the brain of your water treatment system. It measures the actual amount of water your household uses and decides exactly when the system needs to regenerate (that is, flush itself clean and recharge). It also manages backwash cycles, washing away trapped sediments by gently lifting and rinsing the media bed inside your tank. This ensures your softener or filter continues to work at full capacity without wasting salt, water, or energy. The digital display shows you system status and lets you adjust settings—all without complicated steps.

What’s Going On Inside the Tank

This control valve doesn’t include the media itself—that’s the part that actually treats your water by removing hardness or impurities. Instead, it operates the process that keeps the media clean and effective. The media bed might be in a tank sized for your home’s water demand, and we confirm those details with you to make sure everything fits your system perfectly.

The Vessel and Capacity It Works With

The control valve is designed to fit residential softener or filter tanks of various sizes. We’ll match it to the tank size and plumbing port dimensions you have, ensuring the valve can handle your typical water usage smoothly. While the valve powers the system’s cycles, the tank holds the treatment media that does the actual cleaning or softening, and we work with you to confirm the right tank size for your household.

Is This Control Valve Right for Your Home?

This control valve suits typical residential water softeners and filters. If your system uses metered regeneration and you want a reliable, easy-to-use control that tracks real water use and runs automatic backwash cycles, this valve fits well. Larger homes or commercial setups might require more heavy-duty control heads, so if your water use is exceptionally high, we recommend confirming your needs with us before ordering.

Maintenance and Living with the Control Valve

Once installed by your licensed plumber, this control valve requires minimal maintenance. You’ll occasionally check the digital display for alerts or status updates and may need to adjust settings for changes in water use or media type. Since it counts actual water flow, it avoids unnecessary regenerations, saving you effort and materials over time. The valve’s design supports long-term reliability when paired with routine system upkeep.

What This Control Valve Doesn’t Do

This valve itself doesn’t treat or remove contaminants directly; it manages the cycles of your softener or filter system that houses the treatment media. It won’t fix water quality issues on its own—you’ll need the appropriate media tank for that. If your problem is specific to chemical contaminants, bacteria, or sediment, ensure your system’s media is selected accordingly.

Who this size is right for

Practically speaking, this is a control head, so the size it suits is set by the tank it sits on and the service flow the house needs, not by the head itself. On standard residential porting that is a single-family home.

Because no fixed capacity is published for this item, the honest answer is that your own figures decide it. Send us your peak flow in gallons per minute and a water test and we will check the sizing for you, at no charge, before you buy.
