When your water softener’s performance depends on precise control valve components, the CS-PISTON Connected Series Replacement Piston offers a dependable and durable solution. Designed specifically for Connected Series control valves, this replacement piston ensures smooth operation by maintaining consistent flow and pressure regulation, helping you avoid common water treatment issues like inconsistent softening or valve malfunctions.
Key Benefits
- Restores optimal valve function to maintain soft water quality
- Prevents leaks and pressure drops with a secure, precise fit
- Enhances the longevity of your Connected Series control valve assembly

How It Works
The CS-PISTON works as a critical moving component inside your Connected Series control valve. It regulates the flow of water through the system by creating a tight seal that controls the piston’s movement. This ensures that water softening cycles operate smoothly, directing water through the resin beds efficiently and preventing unwanted bypass or leakage.
By replacing a worn or damaged piston, you restore the valve’s ability to maintain consistent pressure and timing during regeneration cycles, which is essential for effective water softening performance.
What to Expect
After installing the CS-PISTON, you’ll notice immediate improvements in valve operation, including smoother cycling and reduced water pressure fluctuations. During the first few days, your water softener will operate more consistently, delivering softened water as expected without interruptions.
Over time, this replacement piston helps maintain valve reliability, reducing the need for frequent maintenance or premature component replacements. It supports long-term system efficiency by ensuring your water softener’s control valve continues to perform within manufacturer specifications.
