4” Bottom Drain ( No Air )- Evolution Aqua

Product details

4” Bottom Drain ( No Air )- Evolution Aqua is a 4-inch aquarium bottom-drain assembly designed to pull detritus from the tank’s base into your filtration system. Built around a Schedule 80 PVC drain body and compatible with a horizontal pipe connection, it uses a center standpipe to manage the flow path while the “No Air” design supports a bottom-drain setup that does not rely on air injection. This kind of plumbing component is commonly used in sumps and overflow-based systems where you want solids removal concentrated at the lowest point of the aquarium.

• Heavy duty Schedule 80 PVC construction for robust, long-term plumbing use
• 4” horizontal pipe fitting for connecting the drain to your return/collection plumbing
