Review on Enhance Performance with American Standard 3280.040-0070A 4-Inch Flush Valve Assembly for Champion One Piece Toilets by Satish Tegan

Check the warranty on the toilet. Most are valid for ten years from receipt or date of manufacture in the tank. Call American Standard and they'll deliver it in a couple of days for free. Also install a connection between the toilet and the tank to replace the gaskets at the same time as dismantling the tank. To empty the tank, soak up the remaining water with the giant sponge and then wring the water out into the bucket.
