Which term describes a condition where a receptacle is filled beyond its flood level rim?

The term that best describes a condition where a receptacle is filled beyond its flood level rim is "flooded." In plumbing terminology, when a receptacle, such as a sink, bathtub, or toilet, is filled to the point where the water level exceeds the maximum allowable level (the flood level rim), it becomes flooded. This condition indicates that the receptacle is unable to handle the volume of water it currently contains, leading to potential overflow and water damage.

In contrast, while "overflowed" might seem somewhat relevant, it refers specifically to the act of water spilling over the edges after reaching the flood level, rather than the state of being filled beyond that point. "Drained" implies the removal of water, which does not apply to the condition of excess water in the receptacle. "Leaked" suggests water escaping from a container due to a fault or break, which also does not accurately capture the state of being filled beyond the intended level. Thus, "flooded" is the most appropriate term to use in this context.
