SENSEN Non Return Valve

The SENSEN Non Return Valve is a simple, essential safety accessory that protects your air pump from water backflow. Installed inline on airline tubing, it ensures air travels in one direction only, helping prevent water from siphoning back during power outages or when pumps sit below the waterline.

Ideal for hydroponic reservoirs and aquarium-style aeration setups, this low-cost valve helps prevent pump damage and unwanted leaks. A smart addition to any air stone or diffuser system for safer, more reliable operation.
