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.
The membrane and backing plate on the Spindrifter bottom drain fits into a recess in the specially manufactured dome (provided). The recess in the Spindrifter bottom drain prevents the membrane from becoming detached. The complete assembly is secured to the Spindrifter bottom drain by means of a stem, which also provides the air inlet. Most water pipe sizes can be accommodated, the customer to specify. The air inlet is via a nickel plated connector.

Spindrifter 1 Inch Direct Air Feed Kit
The Spindrifter Direct Air Feed Kit allows you to hook up your air pump direct to the Diffuser; this means no Airline has to be threaded down the 1″ pressure pipe. This has a number of advantages but the main one is no water can find its way down the 1″ Pressure Pipe, which potentially will hold stagnant water and the dreaded blanketweed.
The Spindrifter bottom drain is known worldwide for its quality and design. The Spindrifter bottom drain completely replaces the “Standard Bottom Drain.”
The most noticeable feature of the Spindrifter bottom drain is the extra connection in the sump of the drain. This is where the machined Direct Air Feed connector glues in, supplying Air to the main diffuser stem. 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.
The second part of the Direct Air Feed glues on the end of the 1″ pressure pipe which typically will be located in the filter house, enabling you to connect to the Air Pump.
This Direct Air Kit also prevents any back pressure, causing premature failure on your Air pumps.
