The Rhino II is the best designed 4" bottom drain for use in Gunnite, Shotcrete or Concrete but will also work excellent in 45 mil EPDM liner ponds. The Rhino II 4" bottom drain has an air diffuser dome for added aeration. Your air is pumped in a separate PVC line next to the 4" PVC drain line. Remember that aerated bottom drains like the Koitoilet I and Rhino II require an air pump like the Medo Air Pump.

Quality materials and superior construction differentiates the Rhino II 4 inch bottom drain over other bottom drains. Some of the features that sets this drain apart from the others:

  • 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.
  • 3" height over the horizontal discharge port for more concrete over the horizontal discharge port.
  • Direct pipe connection into the air bladder.
  • Rhino II 4" bottom drain with air dome contain an air check valve to prevent water entering the air line.

Very nice drainReview by Tim. W
I just built a new pond and used this bottom drain.It is really made tough. I really like the addition of air to my system without running air lines and air stones on the bottom of the pond.
