ABSTRACT:
Water testing apparatuses and methods for detecting contaminants in water supplies, such as from wells or other domestic water sources. The apparatuses are for use in reservoirs, such as a water closet of a sanitary toilet. They include an enclosure which defines an interior chamber which is intermittently charged with water. The water charged to the interior chamber is passed through one or more filters, preferably a packed column, which removes or otherwise indicates the presence of contaminants in the water. A counter measures the water passed through the system. Water is discharged from the interior chamber using a siphon. The siphon and restriction of flow caused by the filters help control the direction of flow and substantially prevent backflow. The summit of the siphon includes a relief valve for venting gas during filling of the siphon discharge.
