I need a back flush toilet (not a wall hung unit) and after reading all the comments I don't know which one to purchase. My choices appear to be American Standard (bad reviews) Gerber, Manfield & Zurn. I live about an hour from Houston, Texas but don't know where to buy a back flush toilet (ADA height would be nice). The internet has good prices but returns sound like a nightmare. What's a girl to do? Any help would be appreciated. Ann from Baytown
