WSP Softener Control Valve (WSP-CV-9500)

Your skin and hair feel softer and less dry after a shower, but only when the water softener is working right. The control valve is the part that keeps the softener running on schedule, making sure hardened minerals don’t sneak through and cause that tight, scratchy feeling you want to avoid.

Keeping Your Water Softener on Track

The WSP Softener Control Valve manages the timing of your water softener’s cleaning and regeneration cycles. It decides when the system needs to flush out the minerals it has collected, so the softener’s resin stays effective. This timing isn’t fixed—it adjusts based on actual water use, which helps save salt and water that would otherwise be wasted on unnecessary cycles. You set the schedule, and the control valve handles the rest with reliable 24-volt power and a microprocessor that tracks your water flow.

How the Control Valve Works Inside Your Softener

This valve is the brain of the softener system. It directs water through the tank filled with cation exchange resin, the material that traps hardness-causing calcium and magnesium. During regeneration, the control valve shifts to backwash the resin, clearing out trapped minerals and preparing it to soften your water again. The smart electronics inside prevent resin fouling—clogs that reduce efficiency—and keep softened water flowing without interruption.

Compatibility with 9500/1600 Water Softener Tanks

The valve fits standard softener tanks designed for 9500/1600 systems. These tanks hold the resin and are sized for typical residential water use. The valve’s connection ports match these tanks, ensuring a proper fit and optimal operation. While the valve itself doesn’t filter water or soften it directly, it controls the cycles that keep those processes running smoothly.

Who Should Choose This Control Valve

This control valve is for homeowners who already have, or plan to maintain, a water softener system using 9500/1600-style tanks. It suits typical residential setups where soft water is needed consistently throughout the day. If your home’s water use is unusually high or your system’s tank is a different size, you may need a different valve or system designed for those conditions. Confirm sizing with your plumber or water treatment professional before ordering.

Living with the WSP Softener Control Valve

Once installed by your licensed plumber, this valve requires little day-to-day attention. It runs automatically, adjusting regeneration based on your water use. Maintenance mainly involves occasional checks to ensure the valve is clean and free of debris. Over time, electronic parts and seals may need replacement, but these are available through Water Softener Plus for ongoing serviceability.

What This Valve Can’t Do

This valve doesn’t soften water by itself—it controls the softener’s operation. If your system needs a new resin tank, filters, or plumbing parts, those components must be sourced separately. Also, it isn’t a complete softener system; it’s the control part that fits onto compatible tanks. For managing other water issues such as iron, sediment, or chlorine, consider other treatment devices suited for those problems.

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.
