A frustum-shaped toilet bowl (26) includes a reversibly rotable saucer-shaped seal (46), or saucer. The saucer can automatically be rotated upward hermetically to compress closed against a sealing ring (48) that surrounds the outside of the bowl near its bottom outlet (32). The saucer is normally closed to prevent sewer gases from entering a bathroom from an adjoining drain line (36). The closed saucer can retain human waste or test balls in the bowl or, when opened, permits them to free-fall of their own weight into the drain line. The bowl has opposing water outlets (42) which are connected to flushometer valve (34), which is connected to a source of pressurized water. Depressing a button (74) automatically provides a wet spot in the bowl to prevent falling feces from sticking to the bowl. Depressing the button a second time opens the saucer and causes additional water to stagger flush solids while they are moving in the pipe. A two-stage staggered flush propels solids further than releasing the wet spot water and the additional water into the pipe together. A urine flush uses about 250 ml (0.25) gallons and a feces flush about 4.0 liters (1.0 gallon) of water. A 2.00 to 3.00-liter (0.50- to 0.75-gallon) flush carries 100 test balls about 18.2 meters (60 feet) in the drain line.
