In terms of design, what is a common characteristic of siphon jet toilets?

Siphon jet toilets are known for their effective flushing mechanism, which relies on a siphoning action to remove waste. A wide trapway is a common characteristic of siphon jet toilets. This design facilitates a smooth and efficient flow of waste and water during the flushing process, preventing clogs and ensuring the toilet can handle larger volumes of waste. A wide trapway minimizes resistance as solids are pushed through, enhancing overall performance and reducing the chances of blockages.

While other characteristics like tank-less operation or low-profile design might pertain to different toilet types, they do not specifically define siphon jet toilets. Additionally, the flush mechanism can vary in complexity, but the defining aspect here is the wide trapway which is integral to the siphoning action that these toilets utilize effectively.
