WSP Meter Assembly - 3"

The WSP Meter Assembly - 3" is designed to measure exactly how much water your system uses so it regenerates only when needed, not on a set schedule. This precision helps avoid wasteful running and unnecessary wear on your water softener or filter control valve.

What a plumber first sees at the valve

When a plumber inspects your water softener or filter setup, one of the first things they notice is the control head on top of the tank. In systems that regenerate on a timer, this head simply counts down the hours and triggers a cycle regardless of how much water you’ve actually used. The WSP Meter Assembly replaces that with a flow-metering head. Instead of guessing, it tracks the water volume passing through, so your system only regenerates when it really needs to. The plumber will see a sealed connection with precise flow measurement ports, ready to fit tanks with a 3-inch valve opening.

How the control head manages water use

The heart of this assembly is its metered control head. It counts the gallons or liters of water you use in real time, providing accurate data to the softener or filter valve. This means your system regenerates based on actual water consumption, not on a fixed clock. By regenerating on demand, you avoid wasting salt, water, and wear on the system components. The sealed ports help prevent leaks and ensure consistent performance over time. This metering control head is compatible with a range of control valves designed for 3-inch tank openings.

The role of this assembly without media

This meter assembly does not contain any media itself. Instead, it fits on top of your existing 3-inch water treatment tank, which holds the media that treats your water—whether that’s softening resin or filtration material. Its job is to monitor water flow precisely, so the media inside your tank works efficiently and regenerates at the right intervals.

Tank compatibility and practical capacity

The meter assembly is designed to fit tanks with a 3-inch valve flange and porting. This sizing makes it suitable for typical residential water softeners or filtration systems that use 3-inch connections. The actual water treatment capacity depends on the size of your tank and the media installed within it, not on the meter itself. The meter simply ensures your system regenerates according to your household’s water use rather than an arbitrary schedule.

Is this meter assembly right for your home system?

This assembly suits residential water treatment systems equipped with 3-inch tanks. It’s ideal if you want to avoid the inefficiency of timer-based regeneration and prefer a system that adjusts to your actual water consumption. If your system uses a smaller or larger valve size, or a different tank configuration, you’ll need a meter assembly compatible with that size instead. Confirm your tank’s valve diameter before ordering to ensure a proper fit.

Living with the WSP Meter Assembly

Once installed by your licensed plumber, the meter assembly requires little maintenance beyond routine system upkeep. Its sealed connection ports and durable design reduce wear and accuracy loss, cutting down on service hassles. Unlike older timer models, it helps your system run only as much as it needs. Periodic checks by your plumber can confirm the meter is accurately tracking flow, but you won’t have to replace or recalibrate it frequently.

What this meter assembly does not handle

This assembly only measures water flow and controls regeneration timing. It does not filter, soften, or treat water by itself. For addressing hardness, sediment, iron, or other water quality issues, you will need the appropriate media inside your tank. This product also doesn’t include bypass valves or hoses; those must be arranged separately by your installer.
