Air Manifold and Taps : 55 gal drum
The commercial bead filters that use air to wash the beads use a blower for
a hot tub. It is a high flow blower. The air is introduced through the
intake piping that normally runs water from the pump, using a backflow
preventer on both the pump feed and the blower feed. This keeps the air
from going back through the pump, and water from going into the blower. A
means of having the return water from the filter to the pond, diverted to
waste during the cleaning phase is needed to discharge the dirty water to
sewer or to flower beds, and then when clean, the water sent back to the
pond.
This will be no problem for me. My french ditch pump force water to the
front yard. Thanks for straighten me out.
