My new American Standard Titan toilet had a leak. I determined it was coming from the tank and assumed it was most likely the tank bolts. I took the tank off and reinstalled it but it still leaked. I took it apart again and figured out the rubber gasket where the fill valve connects to the tank was defective when installed at the factory. Due to your poor manufacturing, I had to remove and replace the tank twice and had to risk cracking the tank two extra times. Plus you caused me to waste my time redoing it. Don't think I can recommend American Standard to anyone I know.
