ABSTRACT:
A sanitary pan flush cistern which includes structure to permit full-flush or partial flush as required. The cistern is a conventional lidded container housing usual outlet valve on a valve-rod, a press-button in the lid to open the valve and a float-controlled water admission valve. It also houses a pot which in turn houses the outlet valve, and has a normally open doorway furnished with a lid. Linkage connects both the lid and the valve-rod to the press-button so that when the latter is pressed the valve is opened and a full flush passes the outlet valve from the pot and from the outer vessel by way of the normally-open door. When the press-button is lifted the outlet valve opens as before but the door is closed so that the flush is limited to the content of the pot. In accordance with the invention the linkage is length adjustable and the press-button preferably non-rotatable.
