Abstract
Disclosed are valve assemblies for controlling flow from a toilet bowl to a trap way. In one form there is a cartridge unit in which a pivotable gate is mounted. The gate can swing from a blocking/closing position to a position in which it is essentially hidden away in a recess out of the main flow path. The surface of the gate facing the bowl is inwardly dished to further facilitate flow optimization.
