A water source (12, FIG. 1) is provided for mounting on a toilet housing (32) rearward of the toilet bowl (18), which has a small rearward-to-forward depth (D) and low height (H), and which enables close control of the flow of water and any vacuum to the toilet bowl and its outlet. The source includes a frame (40) for mounting on the rearward portion of the toilet housing, the frame having two wide holes (50, 52) and a diaphragm device (54, 56) extending across each hole to separate water regions (60, 62) from air regions (64, 66) that lie on opposite sides of the diaphragm. The holes and diaphragms form two horizontally spaced water supply units 42, 44 that lie on opposite sides of the toilet bowl outlet 24 to efficiently use space. A spring or weight biases each diaphragm to compress the water region. The two water regions are connected together and to a flush valve (14) for supplying water to the toilet bowl. Where a vacuum assisted toilet is used, at least one of the air region is connected to the toilet bowl outlet (24) to apply a vacuum thereto when water flows out of the water regions.
