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. 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.
