Spindrifter Aerated Bottom Drain

The Spindrifter aerated bottom drain is known worldwide for its quality and design. This Spindrifter aerated bottom drain completely replaces the “Standard Bottom Drain.” The most noticeable feature of the Spindrifter bottom drain is the extra 1 inch DIA Pressure pipe connection in the sump of the drain. This allows the air supply hose to enter the sump independent of the water outlet pipe, thus eliminating the possibility of restriction to the water flow and somewhere else for blanket weed to attach.
