Koi Collection Aerated Bottom Drains

Koi Collection Aerated Bottom Drains

This bottom drain is known for its quality and design. This unit completely replaces the "Standard Bottom Drain."

The most noticeable feature of this bottom drain 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 on the bottom drain fit into a recess in the specially manufactured dome (provided). The recess in the dome prevents 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 on the bottom drain is via a nickel plated connector.
