About this item
- This aquarium check valve protects your air pump by preventing water from backflowing through the hose during a power outage or pump pause. A must-have accessory for your aerator.
- The air pump check valve measures about 5.5 x 1.4 cm and fits 4mm diameter air hoses and all standard aquarium air pumps, but not for CO2 systems.
- Turn off the air pump to harvest fish and shrimp eggs more easily. Our aquarium check valves prevent the pump from filling with water when turned off. You will receive 15 pump check valves. Sufficient amount is perfect for fish and shrimp farmers.
- The oxygen pump check valve is made of durable plastic and can be tightly connected to the hose without air leakage. Durable and can be used for a long time without making noise.
- There is a black arrow on the inside of the check valve, and the end of the arrow is the inlet connecting the hose on the side of the air pump. If the water outlet is stuck in the aquarium air valve, use a toothpick to push it from the water inlet side to the water outlet side.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
