Pentair EU9 Debris Valve

The Pentair EU9 Debris Valve is a replacement part designed to retain collected debris inside the bag assembly for compatible pressure-side automatic pool cleaners. It helps improve cleaning performance by preventing debris from falling back into the pool through the vacuum intake.

Key Features

OEM replacement valve for select Pentair / Letro / Kreepy Krauly pressure-side cleaners.
Keeps leaves and floating debris from being expelled back into the pool intake throat.
Easy to replace—typically accessed by removing the bag assembly on the cleaner.
Made from durable rubber material suited for repeated use in pool environments.

Technical Details

Part Number: EU9
Application: Debris valve for pressure-side automatic pool cleaners
Compatible Cleaner Series: Legend, Legend II, Legend Platinum pressure-side units
Material: Rubber flap / valve assembly

Installation & Compatibility Notes

Before replacing the valve, turn off the pool circulation pump and release any residual pressure in the cleaner system. Remove the debris collection bag or collar to expose the old valve. Align the new EU9 valve in the same orientation, secure or reinstall the bag assembly, and restore system operation. After installation, observe the cleaner to verify that debris is retained in the bag and not escaping the intake.

Maintenance Tips

Inspect the valve regularly for signs of wear, cracking, tearing or deformation—replace when performance declines.
If debris is being expelled back into the pool or cleaning efficiency is reduced, the valve may be worn and due for replacement.
Keep the bag assembly and valve area free of large debris or objects that could block the flap or restrict its function.
Use as part of routine seasonal cleaner service to maintain optimum performance.

Why Choose This Valve?

Installing the Pentair EU9 Debris Valve restores proper retention of captured debris in pressure-side cleaners, helps maintain pool clarity, and reduces the need for re-cleaning. It is a low-cost replacement that supports smoother cleaner operation and fewer service calls.
