Water Volume Issues
Toilets hold a lot of water. Drano needs to sit on the clog. It needs contact time to work. The large water volume dilutes Drano. It washes the cleaner away quickly. This reduces its effectiveness. Sink drains have less water. The clog is closer to the drain opening. Drano can reach it there. In a toilet, the clog is deep. The water pushes the Drano away. It just sits in the bowl.
