WSP Control Valve, Fleck 9100/1600

If your water softener or filter isn't running its cleaning and salt-replenishing cycles properly, the control valve could be the cause. The WSP Control Valve, Fleck 9100/1600, is the part that manages these operations, helping your system work efficiently and last longer.

The problem you’re facing

You might notice your water softener or filter isn’t cycling through its backwash and regeneration stages as it should. Maybe your softened water isn’t as soft as before, or the system seems stuck in one mode. This often means the control valve isn’t working right. Without it running on schedule, your system can’t clean or recharge itself properly.

Why this is happening

The control valve is the mechanical brain of your water softening or filtration system. It directs water flow during different stages, like backwashing to clean the media or regeneration to refresh the resin. If this valve wears out, jams, or fails to meter water usage correctly, the cycles get out of sync or stop. The Fleck 9100/1600 platform uses a metered system, so it counts how much water you use to decide when regeneration should start. If it doesn’t do this, your softener can’t stay on top of the job.

What it’s costing you to leave it

When the control valve fails, your system won’t regenerate properly. That means minerals like calcium and magnesium stick around, causing scale buildup on your water heater and plumbing. You’ll likely notice harder water stains, your soap won’t lather well, and appliances might work harder or wear out sooner. Plus, fixing or replacing other parts could cost more than addressing the valve alone.

How this system fixes it

This WSP Control Valve is built on the Fleck 9100/1600 platform, which uses a metered control method. It measures your water use and triggers regeneration only when your system actually needs it. This precise timing ensures efficient salt and water use and keeps the softener or filter running smoothly without unnecessary cycles or downtime.

What this system can handle

The valve controls softeners and filters that use the Fleck 9100/1600 series configuration, managing water flow for units designed for typical household or light commercial use. It can handle the standard flow rates and pressures compatible with 3/4-inch meter valves, maintaining consistent water delivery during all stages of operation. This valve suits systems up to the capacity designed for this model, so it’s a reliable choice for replacing worn or faulty control heads on these setups.

What you actually get

You receive the WSP Control Valve built on the Fleck 9100/1600 platform, specifically the FL91/16M-0.0 model. It comes as the control head only, without a bypass valve or discharge hose. It includes the integrated cover to protect internal parts and the mechanism that meters water use and switches the valve through its programmed cycles.

Is this the right size for you?

This valve fits softeners and filters designed for 3/4-inch Fleck 9100/1600 valve heads. If your system uses a different control valve size or platform, or if you require a larger flow capacity, you’ll need a valve specifically sized for that. Confirm your current system’s valve matches this model before ordering to ensure compatibility.

Living with it

Once installed, this valve functions automatically, tracking your water use and managing regeneration without daily input. It requires minimal maintenance beyond occasional cleaning or servicing by your plumber if you notice irregular operation. The valve’s durable construction means it should last years under typical conditions, with parts available if repairs are needed.

What it won’t do

This valve does not treat water itself; it simply controls the softener or filter’s operation. It won’t fix issues unrelated to valve control such as resin media problems, salt blockages, or supply line leaks. For those, additional parts or service would be necessary.
