Pond Plumbing » Bottom Drains

The Koi Toilet Series drains have made a stand in todays pond market. They are built to last and offer many features that other drains do not offer.

• Sweep bottom design to eliminate trapping debris.
• Full 4" height over horizontal discharge pipe.
• 1" Air supply connection at the bottom through center column.
• Screws are fully encapsulated in large and strong screw pockets.
• Threaded center column for easy disassemble and maintenance.
• Wide and thick flange for better liner grip.
• Slanted air dome and high quality air diffuser with internal check valve function.

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.

• Specially Manufactured Dome
• Recessed Air Diffuser
• Socket Solvent Welded
• Triple Run Welds
• 4" Water Outlet
• 1" Air Inlet
• Fish Safe
• 4,500 openings in the air diffuser
• For Concrete or Liner Ponds

The membrane and backing plate of the Spindrifter fits into a recess in the specially manufactured dome (provided). The recess in the dome prevents the membrane from becoming detached. The complete assembly is secured to the bottom drain by means of a stem, which also provides the air inlet via a nickel-plated connector. All constructional materials are PVC and self-tapping stainless screws. All welds are triple run, suitable for concrete, fiberglass, or liner pond construction.

Removes debris that settles to the lowest point of the pond. No excavation required- allowing for easy retrofitting of existing ponds.

Connect to any suction line, pump or skimmer with pvc pipe or flexible hose. Even works great with swimming pool flex hose.
