EasyPro 3" Bottom Drain with Air Diffuser (MPN BDA)

Adding a bottom drain to a pond has proven to be beneficial for many pond builders. It helps in keeping the pond clean by allowing easy removal of fish waste and other debris that accumulates on the pond's bottom. Without a bottom drain, ponds that are over 2 feet deep can become stagnant. The features of this bottom drain include increased air circulation and cleaning capacity. It is equipped with dual rubber gaskets and six stainless screws for a water-tight penetration through the liner. Additionally, it is designed to be used with 3-inch schedule 40 PVC fittings and pipe. The bottom drain also comes with a 10-inch rubber air diffuser that connects to the top section. It includes a half-barbed inlet fitting, and it is recommended to have an airflow between 0.5 to 1.5 cubic feet per minute through the diffuser.
