I have an Eljer corner toilet with a hairline crack in the tank.Been VERY unhappy with the lo-flow performance, and would like to replace with a toilet w/ FlushMate or similar feature to assist flush. Is Eljer the only company making a corner model; or is there a way to put a regular toilet in the corner without having to add the expense of moving sewer hole, replacing tile, etc. Any help/advice is appreciated, thanks.
