The Rhino 90 Degree Drain is fully constructed of Sch 80 PVC and comes ready to install onto your horizontal plumbing removing steps from assembly time to make your assembly process easier. (4" Shown in Picture)

Aquadyne Rhino Drains set the standard for quality and dependability. They are easy to install and will provide a lifetime of worry free service. Rhino drains are made from Schedule 80 PVC and designed by computer generated machine fabrication and are thermal welded by hand to assure top quality dependable structural welds. As you will see, the quality of our drains is paramount over any other drain on the market today. Great efforts have been made to fabricate these drains to a commercially durable standard so that the 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. Compare the engineering of Rhino bottom drains to any on the market and you will see the quality is evident.


  • 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.
  • 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 entering the airline.
  • Rhino drains do not use any injection molded components that weaken other drains.

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. 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!

This works perfectly and does a great job picking up leaves and debris from the bottom of my 7,000 gallon koi pond. leaves, sticks, gunk, you name it - I find all kinds of **** in my pump basket. Great product.

Best drain ever.

Simple to install. Works really well. My application was for a 2500 gallon above ground fish tank. I selected these for their construction. Extremely well built and sturdy. I would have no concerns using these buried below a concrete pond. Awesome product at an awesome price. Just be careful with smaller fish as they can get below the top plate.

Good recomendation

I called Play It Koi for some advice with my koi Pond project who recommended this Rhino bottom Drain. I Placed the order over the phone which was easy and painless. The Rhino arrived in 2 days and I also ordered some UV bulbs showed up safe and sound a day after that. Pleased with the recommendation and the service I got.
