    What is a syphon jet flush toilet? I am putting in a new toilet on the fourth floor of my house and the water pressure is not that great. Does a syphon jet flush toilet need alot of pressure or is it like a regular toilet that is a gravity fed toilet?

    A siphon jet bowl has a jet at the front that water comes from, and it starts the siphon.

    Old style bowls only wash down from the upper rim holes.

    So I don't have to worry about having strong water pressure? Its not like a public restroon 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.
