Ball passage refers to the size of the ball that can pass through a toilet trapway without causing a blockage. It is a critical factor in toilet design, as it determines the likelihood of clogs and the toilet’s flushing efficiency. A larger ball passage allows for better waste removal, reducing the chances of blockages and the need for multiple flushes. The standard size for ball passage in toilets ranges from 1.5 to 2 inches, though some high-efficiency models offer larger trapways to enhance performance. Understanding ball passage is important for homeowners and plumbers when selecting a toilet, as it affects both functionality and maintenance requirements.
