Flushing Kohler parts and customer service
Seal has been leaking for a while so I scan the QR code attached to the tank lid and it offers a website that doesn’t exist for parts. I found the guide that comes with the toilet and find the list of parts that seemed to match my toilet. ( not a wall mount, specifically a dual flush option). Ordered 2 seals that would replace mine and they arrive far too small for the application. What a complete disappointment
