So I don't have to worry about having strong water pressure? Its not like a public restroom toilet?
Most toilets for home use have a tank combined with the siphon jet.
It can either be a gravity tank, which works with any pressure over 20 PSI
or a pressure assist, they would need more pressure to work well.
Commercial valves rely on large pipes to each toilet.
You will never be able to use those in a home successfully without adding a storage tank behind the wall.
If you're buying a toilet with a tank, then the 20 PSI is all you need.
With the siphon flush, some water comes from the small hole on the near side of the bowl, and the rest comes from the rim as it rinses down the bowl.
