Description

This Air Pump Non-Backflow Check Valve Pack (2) is designed to help prevent water from back-siphoning down your airline tubing during a power outage or when the air pump is switched off. It’s a simple, low-cost safeguard for aquariums, DWC reservoirs, and any setup running airstones.

Why you’ll like it

  • Helps prevent back-siphoning through airline tubing (as stated)
  • Protects air pumps and nearby electrics from water backflow (common-sense benefit)
  • Easy inline installation on standard air line tubing
  • Pack of 2 for multiple lines or spare on hand

Best for

  • DWC/RDWC reservoirs and nutrient tanks with airstones
  • Aquariums and ponds using air pumps
  • Any setup where the air pump may sit below the waterline
  • Systems running multiple airlines that need one-way protection

How to use

Cut the airline tubing and install the check valve inline, ensuring the flow direction is correct (arrow/marking toward the airstone). Place it above the waterline where possible for easier inspection.

  • Install inline with correct direction (toward the tank/reservoir)
  • Test airflow after installation to confirm correct orientation
  • Replace if airflow becomes restricted or the valve leaks over time

Compatibility

  • Hydro: Yes (airline protection for reservoir aeration)
  • Coco: Indirect (for reservoir aeration only)
  • Soil: Indirect (for water storage/holding tanks only)
  • Systems: Standard airline tubing and air pumps (assumption: common airline size)

What’s included

  • 2 x Non-Return (One-Way) Air Pump Check Valves

Notes

  • Always confirm flow direction before use to avoid restricting airflow
  • Check valves are a safeguard—also use a drip loop and keep power points dry (general safety)
  • Inspect periodically, especially in humid grow spaces
  • Keep out of reach of children
