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.
