Frequently Asked Questions
This product is sold in five pack size options: 1, 2, 3, 5, or 10 pieces. Purchasing in larger quantities reduces the per-unit cost and ensures you have spare check valves on hand, which is advisable since these small components can wear out or be damaged during maintenance.
The check valve is made from durable plastic, which is resistant to both freshwater and saltwater exposure. The plastic housing does not corrode, making it reliable for long-term aquarium use. The internal flap mechanism is also plastic, ensuring it remains functional without rust-related failure.
The valve measures approximately 52 x 15mm (2.04 x 0.59 inches). This compact size makes installation straightforward — the valve fits inline with standard 4mm aquarium airline tubing and can be tucked discreetly behind or beneath the aquarium where it won't be visible.
The valve is black. Many aquarium check valves use color coding to indicate installation direction. Confirm the correct orientation (typically with the colored inlet cap facing the air pump) before installing, as a reversed check valve will block airflow rather than allow it.
The internal flap allows air to flow in only one direction — from the pump toward the aquarium. When airflow stops (during a power outage), water pressure from the submerged airline tubing would normally push water back toward the pump. The check valve's flap closes under this reverse pressure, blocking the flow entirely.
Install the check valve in the airline tubing between the air pump and the aquarium, with the correct directional orientation. Position it above the waterline of the aquarium if possible — this adds a physical elevation barrier to back-siphoning in addition to the valve's mechanical protection.
