Gerber Toilets / Do not buy from them
Gerber Toilets have a weak flush and clog easily I have six Gerber 1.6 gpf toilets and they all work the same. Terrible! All six require multiple flushes to clear the bowl and if you use any toilet paper, better hold the flush lever 8 to 10 seconds. This is definitely NOT a flush and forget.
One of the six clogs more often than the others, even when holding the flush lever down, and I'm half tempted to rip two of them off the floor and check for manufacturing differences. How can one be SO DIFFERENT than the other? (Already checked the vent pipe) The Gerber warranty only covers "materials and workmanship" but not performance. You have to call the installer for that. If you go to the Gerberonline.com website, they made sure that this is a product "not found in big box stores" which means you have to work through their distribution network, ie plumbers or plumbing fixture stores.
This toilet is a plumbers delight! It generates all kinds of trouble calls which translates into $$$$$. If I was a plumber, I'd push this product too! But I wouldn't have one in my house ...
