Check Valve for Aquarium Air Pump, Hose Ø 4/6 mm, Clear - Zolux
Protect Your Air Pump from Water Backflow
This Zolux check valve is installed on the air hose, between the pump and the air stone.
When the pump stops (power outage, malfunction), it prevents water from the aquarium from flowing back up the hose toward the pump.
This prevents damage to the pump and stops water from leaking out of the aquarium.
Fittings for Ø 4/6 mm tubing, transparent body, dimensions: Ø 1.5 cm x length 5.5 cm.
In short: Install between the pump and the diffuser, ensuring the air flows in the correct direction.
A small safety measure to include on every air pump, especially if it’s installed below the water level.
Description
A small but essential accessory
When an air pump is installed below the water level, water can flow back down the hose as soon as the air stops pushing.
The check valve allows air to flow in only one direction: toward the aquarium.
In the other direction, it closes and blocks the water.
Features
- Type: Check valve for air circuit
- Compatibility: Ø 4/6 mm air tubing
- Dimensions: Ø 1.5 cm x length 5.5 cm
- Color: transparent
- Brand: Zolux
Installation
1. Cut the air tube between the pump and the diffuser.
2. Connect the pump end and the aquarium end to the valve’s ports, making sure the air flows in the correct direction.
3. Turn on the pump: bubbles should flow out of the diffuser as expected.
ℹ️ Good to Know
If no bubbles come out after installation, the check valve is likely installed upside down: flip it over.
It’s best to install it out of the water, near the aquarium, so you can easily check it.
⭐ Tip from the team: Install a check valve on every air pump, even if it’s mounted high up—it’s a safety measure that costs almost nothing compared to the price of a pump or water damage.
❓ Frequently Asked Questions

Does the check valve reduce the air flow?
It creates slight resistance to the flow of air, without interfering with the bubbling action of a standard air pump.
Is the tubing included?
No, the check valve fits a standard Ø 4/6 mm air hose, sold separately.
