HydroLogic® Stealth-RO™ Quick Connect Float Valve - 1/4in QC

Automated Reservoir Filling Precision-Engineered for Stealth-RO Systems

The HydroLogic® Stealth-RO™ Quick Connect Float Valve is specifically engineered for integration with Stealth-RO™ reverse osmosis systems, providing seamless automated reservoir filling through a 1/4in quick connect fitting that snaps directly onto Stealth-RO output tubing without tools. The adjustable float allows precise water level setting, and the precision-engineered valve ensures reliable shutoff at the set level — preventing overflow and eliminating the need for manual monitoring. User-friendly installation and maintenance make this a practical, long-term solution for any Stealth-RO operator.

Key Features & Benefits

• 1/4in quick connect fitting — pushes directly onto Stealth-RO™ 1/4in output tubing for tool-free, leak-resistant installation.
• Adjustable water level — set your desired reservoir fill level precisely and the valve maintains it automatically.
• Precision-engineered shutoff — reliable valve action ensures accurate level control for consistent water quality and reservoir management.
• Hassle-free installation and maintenance — quick connect design simplifies both initial setup and any future servicing.
• Prevents overflow — automatic shutoff at the set level eliminates the risk of reservoir overfilling during unattended operation.

Who Should Use This

HydroLogic Stealth-RO™ system owners who want to automate reservoir filling and stop manually monitoring water levels during RO filtration runs.

Compatibility

Designed for HydroLogic Stealth-RO™ systems. Requires 1/4in quick connect tubing. For 3/8in QC systems (Evolution-RO 1000, TALLBoy®), use the corresponding 3/8in QC float valve.

Frequently Asked Questions

Does this valve work with other RO brands that use 1/4in QC tubing?

Yes — the 1/4in QC connection is standard across many RO systems, so this float valve will work with any compatible 1/4in QC output line.

How do I adjust the shutoff level?

Adjust the float arm position to raise or lower the water level at which the valve closes. Test and fine-tune after installation.

Is there a risk of the valve leaking at the QC connection?

The quick connect design provides a reliable, leak-resistant seal when properly inserted. Ensure tubing is fully seated into the QC fitting during installation.

What if my Stealth-RO produces water faster than I need?

The float valve automatically shuts off flow when the set level is reached, regardless of how fast the RO system produces water — protecting your reservoir from overfilling.
