Aerated Bottom Drain (Concrete)

Aerated Bottom Drain - This unit completely replaces the "Standard Bottom Drain". The most noticeable feature is the extra 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 fit into a recess in the specially manufactured dome (provided).
Price: £137.00


The recess in the dome prevents the the membrane from becoming detached. The complete assembly is secured to the 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. The tube size can be specified by the customer. A connector for tube sizes up to 1/2" bore will be supplied at no extra cost. Weight of the unit 5kg approx.

Stocked drain has 4" (waste ) socket, and 1.5 " high pressure socket for air line.
