Spindrifter Drain
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). 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.
