Rhino - Retrofit Over the Liner - Bottom Drain for 3" Pipe

Product Features
Product Reviews
Simply the best bottom drains on the market!

As with all Rhino Drain products, there are no cheap injection molded parts to break on any drains in the Rhino product line. The Rhino Retro Drain is constructed from heavy duty PVC materials and will not damage your pond liner like cheaper products with sharp edges.

The latest Aquadyne Retrofit Bottom Drain offers a quality innovation for a stable and rugged over the liner bottom drain for those who do not want to install a drain through a liner, or for pre-constructed ponds that do not have a bottom drain. This drain is especially useful for pond and aquatic environments that have pre-existing liner, concrete, or any other situation that would not allow underground plumbing to be installed.

Simply fill the ballast area of the drain with small stone, sand, or other heavy inert material. Then attach a suction hose or rigid plumbing to the side port of the drain and attach to the pump suction line. Place the drain in the center or the deepest part of the pond so that the pump can easily suck up suspended solids and debris from the bottom of the pond. During the winter months, the drain can be easily moved to a more shallow part of the pond leaving the warmer water in the lower parts of the pond undisturbed where the fish collect in colder temperatures.

Keeping solid waste and debris out of your pond is a very important step toward keeping your fish healthy and preserving your own personal sanity with regard to maintaining a cleaner pond.

Often too late, pond owners discover that their ponds begin to fill with leaves, dirt, and debris that require the ponds to be emptied cleaned and refilled multiple times per year, not to mention having to take care of the fish when they are out of their home, plus upsetting the ecology of the pond. A good bottom drain is the first step in keeping the bottom of your pond cleaner and your pond healthier.
