hello my name is shannon foshee i own the champion toilet 4260 also.
i called american standard last week to get a replacement tank i bought this toilet four years ago. i sent american standard a letter i needed a new tank i got hassled about it they wanted me to take pictures of the cracked tank i did not have a camera then the man wanted me to send him pictures of it that's hard to do if you don't have a camera and. he refused to send me a new tank under the ten year warranty. and i get a call today from american standard that they will be sending me a new tank. i.m still waiting on it i will let you know when i receive it.they acted like they wasn't going to.
thanks shannon foshee
