4-inch Bottom Drain
Bottom drains are an important part of any pond. When installing your bottom drain, make sure that it is installed at the lowest point of your pond. This will ensure that the waste will travel into the drain and into your filter system. For larger ponds use this 4" Bottom Drain. A 4" intake allows for larger pumps to grab water from a larger area reducing pump pressure. Should be used with 4" PVC. Comes with an anti-vortex lid, forcing the water to enter from along the ponds bottom. Center stem that can be cut for a perfect fit, making your bottom drain fish safe. SAE standard pipe connection, making pipe hook up a snap. Offset suction port, creates a swirl action inside the drain to help remove debris. Mounting ring, for easy liner installation.

Rhino Bottom Drains
Quality materials and superior construction differentiates the Rhino over other Spindrifter type drains. A few of the problems associated with the Spindrifter have been alleviated in the Rhino design including; Thicker flanges and liner attachment ring that will not flex or crack All attachments are machine fitted for extra strength with no need for gap filling All joints are hand welded resulting in more strength than the speed welds used on the Spindrifter 3" height over the horizontal discharge port for more concrete over the horizontal discharge port (the Spindrifter requires a collar to increase the height over the drain) Direct pipe connection into the air bladder (the Spindrifter requires you to snake an air line through the pipe) Rhino air drains contain an air check valve to prevent water entering the air line.
