First, low water in the toilet BOWL case. If the water in the toilet BOWL is low after flushing, I see four likely causes, in order of most likelihood -. 1) the fill valve is not putting enough water into the toilet bowl.
The siphon in a toilet is shaped like an upside-down U, connecting the toilet bowl to the pipes leading down to the sewer. In the toilet's resting state, most of the water does not rise from the bottom of the bowl through the siphon. However, when water is rapidly added to the toilet via either the flushing mechanism or someone pouring water into the bowl, the siphon tube fills up completely; this in turn creates a pressure differential.
