Premium PVC Bottom Water Inlet for Aquariums
Optimize your aquarium's water circulation with our innovative bottom water inlet fitting, available at Atradesen.com. Designed to be installed at the bottom or lower side walls of your fish tank, this fitting is an essential component for custom sumps and advanced filtration systems.
🌊 Innovative 120° Fan-Shaped Flow
-
Broad Water Coverage: The unique 120-degree fan-shaped outlet distributes return water evenly across a wider area. This powerful flow design effectively prevents fish waste (detritus) from accumulating at the tank's bottom.
-
Space-Saving Profile: The low-profile directional nozzle sits flush against the glass, maximizing the swimming space for your aquatic pets without bulky pipes protruding inwards.
-
Drinking Water Grade Material: Manufactured from 100% safe, non-toxic PVC. Connects seamlessly to your hard plumbing using standard PVC cement/glue.
⚠️ Installation & Sizing Guide (Crucial!)
To ensure a safe and leak-proof setup, please read these Atradesen.com guidelines carefully before ordering:
-
🚨 CHECK VALVE REQUIRED: If you install this inlet below the water line, you MUST install a plumbing check valve on your return line to prevent catastrophic water backflow/siphoning during a power outage!
-
Minimum Glass Thickness: To maintain thread structural integrity, this fitting CANNOT clamp glass thinner than 5mm.
