WSP 210,000 Grain Softener Control Valve - Commercial

When you spend hours scrubbing shower doors and bathroom tiles only to see the same spots reappear, it’s a sign your water treatment system isn’t keeping up. Hard water minerals leave deposits behind, and the control valve that runs your softener or filter plays a crucial role in clearing those deposits away effectively and on schedule.

The part that keeps your softener running smoothly

The control head on your softener or filter is the brain that decides when the system needs to refresh itself. It measures actual water use, then triggers backwash cycles that rinse the mineral-laden media clean and, in softener systems, starts regeneration to recharge the media. This control valve lets you set and program how often these cycles happen and manages the water flow during the process. That means your softener isn’t wasting water or salt, and the media works efficiently to reduce hardness.

Specialized media designed to tackle hard water minerals

Inside the tank, high-capacity cation exchange resin does the heavy lifting. This media targets calcium and magnesium ions, the main causes of limescale buildup on fixtures and in appliances. The resin swaps these minerals for sodium or potassium ions, which don’t leave hard deposits. Because it’s designed for high capacity, the media stays effective longer before needing a regeneration cycle, keeping your water softer and your cleaning chores easier.

A large tank built for continuous, high-demand use

The control valve fits tanks approximately 30 inches wide by 72 inches tall, suitable for a variety of tank types used in commercial or multi-unit residential settings. This size means it can handle a softening capacity of about 210,000 grains, enough to keep up with multiple bathrooms and faucets running regularly without slowing down or needing frequent service.

Best suited for commercial and multi-unit locations

This control valve is made for sites with continuous, high water demand—like apartment buildings, hotels, or commercial kitchens. It manages many outlets at once and keeps the softening cycles efficient in busy systems. If your water use is lighter or your home smaller, a different size would be a better fit; sizing up or down ensures your system runs at peak efficiency and cost-effectiveness.

Sizing is a trade-off, not a target. Go bigger and it regenerates less often and uses less salt per gallon softened; go smaller and you will find the soft water running out before the next cycle. When in doubt, up. Send us your water test if you would like the sizing checked before you order.
