Play It Koi's customers love the Rhino II Heavy Duty Bottom Drain with Air Diffusers. It's the most durable production bottom drain that we've found and is made in the US. They are sturdy, reliable, and a heavy duty solution for your bottom drain needs either under or over the liner applications. 

The Rhino II brings commercial quality to your pond at an economical price. All Rhino drains are made from Schedule 80 PVC and designed by computer generated machine fabrication and are thermally welded by hand to assure top quality dependable welds. All Rhino drains can be installed with extreme confidence in any application by beginners and experts alike.

A bottom drain can be said to be one of the most important parts of a pond installation, in that its integrity is paramount to the success of the entire project. This drain has been designed to make installations easy, with a dependable seal to protect against hidden leaks, which can happen with most other drain flanges available today. By having a wider machined flange, Rhino also allows for a greater margin of error by the installer when cutting the liner to fit the drain. Compare the engineering of Rhino bottom drains to any on the market and you will see the quality is evident! 

Features:

  • Thicker flanges and liner attachment ring that will not flex, distort or crack
  • All attachments are precision 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 other drains.
  • 1/2" airline input
  • 4" Drain pipe
  • Full 3" height over the discharge port of Rhino II equals more concrete over the horizontal discharge.
  • Direct pipe connection into the air bladder. (no snaking an airline through the pipe)
  • Rhino air drains contain a 1.5" commercial air check valve to prevent water from entering the airline.
  • Rhino drains do not use any injection molded components which would weaken the structure.
  • New in 2019, we've added the Rhino II 6 " Industrial size drain w/ air!

What is the key difference in a Rhino Drain?

Rhino drains are not injection molded! Injection molding is typically used to mass produce products for the retail market and is made of cheap extruded ABS Plastic. Other than mass production, injection molded products are typically designed to use minimal quantities of raw material to produce products in shape and form at the minimum amount of cost which of course allows those products to either be sold cheaply and/or produce high profits.

A bottom drain is the first thing to be installed in your pond, and the last thing that you want to fail! Install a Rhino Drain in your pond with confidence!

Perfect Bottom Drains with Nice Aeration Capability

I just built a new pond and used 2 of these bottom drains in my 8000 pond. The construction of them is really durable and tough. I am powering the pair of them with a Hakko 80L and it is the perfect amount of aeration for two. It was nice to get the bonus of aeration without having to run **** air lines and air stones over the top of the liner bottom of the pond liner.

Please Learn from my Mistake

Having made the mistake of purchasing another type of aerated bottom drain in my previous pond that ended up breaking off because it had a flimbsy neck, I vowed on my next pond that I would never do that again. I can't not stress enough what a pain in the neck it was to have to swim down and try to put it back on in 60 degree water.. I tried everything.. superglue, etc. scuba. etc. Ultimately had to drain the entire pond, take the fish out, and prime and glue it back in with a coupler. Then it broke off again and floated up to the surface and It's just not worth it. I'm not hear to bash the other brand but for those pond owners out there considering a bottom drain, I felt it was my duty to warn you of what can happen. Please try to learn from my experience. Don't try to save a few bucks and go for the slightly cheaper option here. It's not worth it! Anyhow, onto the real reason I'm here which is to share my experience with the Aquadyne Rhino II bottom drain. I am extremely pleased with the construction and sturdyness of this bottom drain. Just taking out of the box, I could tell already it was a world apart from the competition. I also like how easy it is to hook up an aeration line. While it's been just a month or so I can tell already, there is no way I'll have the same problems I had with the competitive brand. Haveing tried both Aerated Bottom Drain brands out there, the Rhino II is the way to go. No question.
