INAX Dover Dual-Flush toilet review with pictures and comments.
Inax uses a dual outlet rinse in the bowl that swirls the water to wash out and flush the bowl.
The Dover has a skirted bowl that uses an adapter for the closet flange. The flush valve spins out for servicing. For a standard rough-in, you will need an extra long water supply line. The fill valve is on the opposite side from what we are used to.
