Abstract: There are disclosed embodiments for an anti-ligature flush valve cover. For example, a one-piece flush valve cover is mounted to a solid surface using internal brackets to completely cover a toilet flush valve. A portion of the bracket is recessed from parts that contact the interior of the cover, so that a connector inserted into an opening on the bracket surface contacts the opening spaced away from the interior of the flush valve cover. The cover has a bottom edge that does not extend beyond the edges of the toilet fixture. Structure for a push button assembly for flushing the toilet is also disclosed.

Abstract: The installation block comprises a self-supporting body (1) made of foamed concrete into which a flush tank (2) with an inspection opening (2a) is foamed. A spiral hose (3), which forms a normally empty conduit (9) which empties into the flush tank (2) at one end and leads at the other end outwardly to the front side of the installation block (1), is also foamed into the body (1). To attach a water closet with subdouche, a flexible connecting hose (4), which comprises an attachment piece at the bottom end and at the other end is connected directly to the inlet valve of the flush tank, is inserted into the empty conduit (9).

Abstract: An insulating liner for a water closet tank that has a restricted top opening is disclosed. In one embodiment, the liner is generally rectangular in horizontal cross section so as to define two opposed sets of liner side walls, and one set of the liner side walls converges inwardly and upwardly from a bottom wall of the liner. The liner is formed of a flexible and resilient material so that the liner can be collapsed for insertion into the tank through the restricted tank top opening, and then can be released to resiliently return to its normal configuration where it bears against the interior of the tank side walls.
