Hello,
Thank you for reaching out to American Standard. I’m sorry to hear of the issue you have had with your American Standard product. That model is for a Cadet but you would need to have had the white flapper installed in your original unit. Please contact us at 1-855-815-0004 and an American Standard Consumer Connection Advisor will be happy to assist you. We are available Monday - Friday between 8AM - 7PM ET and Saturday, 10AM - 4PM ET.
Sincerely,
Your American Standard Consumer Connection Team
