What Does an AutoFill Extension Do?
Automatic swimming pool water levelers maintain pool water levels by opening a float-controlled valve when the water level drops below its set point.
The T6EXT provides a 6-inch extension for compatible Fluidmaster valve installations, helping accommodate the required component positioning within the automatic water filling system.
Correct installation and adjustment are important to maintaining the desired pool water level.
When to Replace the Extension
- The original extension is cracked or damaged.
- An existing Fluidmaster valve installation requires the specified extension.
- The extension is missing during AutoFill repair or reassembly.
- A compatible installation requires an additional 6-inch extension.
Verify the original component and current Pentair parts diagram before selecting a replacement.
