Check Valve (one-way flow valve)

Protect Your CO₂ System with Reliable One-Way Flow Control

The ADA Check Valve is an essential safety component for any CO₂ injection setup. Designed to prevent water from flowing back into your CO₂ regulator, it safeguards your equipment and keeps your system running smoothly — giving you peace of mind every time your CO₂ is on.

Why It Matters

• Backflow protection — Stops water from entering and damaging your CO₂ regulator
• Compatible with ADA CO₂ systems — Included with the CO₂ Bubble Counter and CO₂ Beetle Counter
• Easy replacement — Simple to swap out as part of your regular maintenance routine
• Consumable part — Recommended to replace approximately once a year for optimal performance

A small part that plays a big role. Without a functioning check valve, a single pressure drop can send tank water surging back through your CO₂ line — potentially ruining your regulator. Stay protected and keep your planted tank thriving.

Replace annually as part of your CO₂ system maintenance for best results.
