WSP Control Valve (WSP-CV-2815-2)

This control valve manages the backwash and regeneration cycles of your water softener or filter, helping keep scale and sediment from building up inside your system. With its digital controls and customizable programming, it works quietly behind the scenes to maintain your water treatment without wasting water or salt.

Wasting More Than You Think on Scale and Cleaning

Over time, hard water leaves mineral scale inside your water heater, pipes, and appliances. This buildup forces your water heater to use more energy and shortens its lifespan. Your dishwasher and washing machine may need extra detergent to get clothes and dishes clean, and you spend more time scrubbing mineral spots from shower doors and faucets. These costs add up quietly, wearing out appliances sooner and increasing utility bills without obvious warning.

How the Control Valve Keeps Your System Running Smoothly

The control valve is the brain of your water softener or filter. It automatically starts a backwash cycle that lifts and rinses the media bed inside the tank, flushing out trapped sediment and minerals. This refreshes the bed so it can keep working effectively. You can set and monitor the valve’s operation through its digital display, adjusting the timing to match your household’s water use. Proper control means your system uses salt and water efficiently, avoiding waste.

What the Control Head Does—No Media Here

This product itself doesn’t have any media inside. Instead, it fits on compatible filter or softener tanks—specifically those designed for 2815 valve assemblies—and controls the cleaning cycles for whatever media the tank holds. The media inside your tank does the actual water treatment, while this valve manages when and how that media gets refreshed to keep working well.

Built to Fit Standard 2815 Filter Valve Tanks

This control valve fits tanks designed to accept 2815 valve assemblies, making it a straightforward replacement or upgrade for many residential softeners and filters. Its size and porting match common household needs, and the digital control board supports precise and customizable operation tailored to your water conditions and usage.

Who Should Choose This Control Valve

This valve suits homeowners with residential water softeners or filtration systems that use 2815-type tanks. If your system’s valve is malfunctioning, or if you want better control over backwash and regeneration cycles, this valve fits well. For larger systems or those using different tank types, a different valve size or model would be appropriate. Confirm your tank type before ordering to ensure compatibility.

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.
