Two Different Siphon Designs
- American toilets use a self-priming bell (greedy cup) siphon in the bowl, while many UK toilets put the siphon in the cistern (syston).
- The two designs change flush behaviour, water use risk, and user experience significantly.
Practical Uses Of Greedy Cup Siphons
- Greedy cup siphons are self-priming and used in urinal cisterns, lab glassware, and washing-machine softener drawers.
- Their fill-and-siphon behaviour enables periodic or repeatable draining with minimal control mechanisms.
Water Computer Project
- Steve built a water computer using greedy cup siphons and made a video about it after many failed versions.
- He invites listeners to watch the video and acknowledges the hard work behind the successful build.
