=Flush Cycle Operation=
The Model LF-220 Microflush Toilet is an electrically operated drop-through type toilet using approximately two quarts of water per flush. Wastewater is flushed from the bowl through a Hopper and drops directly into a holding tank. A Flapper valve at the bottom of the bowl holds fresh water in the bowl and seals out odors from the holding tank.
