Abstract: A toilet has a pressurized reservoir tank which is connected to a source of water via a backflow preventer, a pressure regulator and an aspirator. The inlet to the tank extends from the upper portion of the tank down into the lower portion to discharge water in the lower portion until a preset pressure in the tank is reached. A flush valve body provides a seal between a captured seal ring and a valve housing and a secondary seal between the bottom of the valve body and an annular surface of the valve housing, which also serves as a downward stop. In an alternate embodiment, a breather hole is provided in the upper portion of the inlet tube to allow for draining of the reservoir tank.

Abstract: A shroud apparatus which mounts under a wall-mounted lavatory to enclose the trap of a lavatory is disclosed. The shroud has upper and lower rearward attachment regions which are hidden by the walls of the shroud when the shroud is viewed from the front. The shroud defines a hollow interior portion which is upwardly open to receive the trap. It also includes a shroud fastening element in its upper rearward attachment region and a securing element that cooperates with said shroud fastening element so as to restrict the forward movement of the shroud. A connector is attachable to the bathroom wall and to the lower rearward attachment region of the shroud.
