WSP Control Valve (WSP-CV-2900)

After a shower, your skin feels smooth and your hair looks healthier, free from the roughness caused by hard water minerals. The WSP Control Valve (WSP-CV-2900) keeps your water softener running efficiently, managing when and how the system cleans itself to maintain that water quality day after day.

How Your Softener Keeps Water Feel Soft

Water softeners need to clean themselves regularly to keep working properly. Without the right control, your system might use more salt than necessary or miss a cycle, letting hardness build up again. You might notice your hair feeling dry or your skin tight after showers, and those mineral spots on faucets and shower doors become persistent. The control valve makes sure your softener refreshes the resin that traps hardness minerals at the right times and in the right amounts.

Precise Control of Regeneration Cycles

The WSP Control Valve features an advanced NXT2 timer that automates regeneration and backwash cycles. It runs an upflow brining process, which means the salt water solution moves upward through the resin tank, using less salt each cycle. You can also adjust settings manually if you want tighter control. This precise timing helps your system use salt efficiently and keeps the resin working longer, which lowers maintenance needs and prevents parts from wearing out too soon.

The Media at the Heart of Treatment

Inside your softener’s tank is a high-capacity cation exchange resin. This resin attracts and holds onto hardness minerals like calcium and magnesium, which cause buildup and affect water feel. The control valve ensures the resin cleans itself properly during regeneration, flushing out these minerals so your water stays soft and your system runs smoothly.

Designed for Tanks with 2900 U&L Configurations

This control valve fits tanks made for 2900 U&L configurations, matching well with residential water softener systems. The size and port arrangement allow the valve to handle typical household water flow and hardness levels, making sure regeneration cycles are properly timed without overworking the system.

Who Should Choose This Control Valve

The WSP Control Valve suits homeowners with a softener tank sized to 2900 U&L specifications. It’s ideal if you want to improve salt efficiency, reduce the frequency of maintenance, and extend your system’s life.

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.
