THE AQUA SAVER acts as an on-demand water

system for In-Sink-Erator commercial disposers. The
Aqua Saver System senses the load of the disposer
motor, and regulates the amount of water necessary
for grinding and non-grinding situations.

OPERATION

The aqua Saver System senses the load on the
disposer motor, and regulates the amount of water
necessary for grind and no grind load situations.

When the disposer is turned on and not grinding
food waste the water flow to the disposer should be at
a slow rate - 1 gallon per minute (GPM).

When the disposer is grinding food waste the
increased load is detected and the water flow rate
increases to insure that the food waste is flushed
through the drain lines.

When the disposer is finished grinding the water
flow decreases back to the slower rate of 1 GPM.
