Aquadyne 3" Rhino Retro Bottom Drain (MPN RHRET-3)

The Aquadyne Retrofit Bottom Drain is designed for ponds and aquatic environments that cannot accommodate a traditional bottom drain installation. It is a durable and reliable solution for situations where a liner, concrete, or other barriers prevent underground plumbing. To set up the drain, you just need to fill the ballast area with small stones, sand, or other heavy inert materials. Then, connect a suction hose or rigid plumbing to the side port of the drain and attach it to the pump suction line. The drain should be placed at the center or deepest part of the pond, allowing the pump to effectively remove suspended solids and debris from the bottom. During the colder months, the drain can be easily relocated to a shallower section of the pond. By doing so, the warmer water in the lower parts of the pond where fish tend to congregate can remain undisturbed, maintaining a comfortable environment for the fish during colder temperatures.
