Giải thích
Per the trap-to-vent distance table, a 1-1/2 inch trap arm may run a maximum developed length of 42 inches (3 feet 6 inches) to its vent. The 30 inch value is for a 1-1/4 inch arm, 60 inches is for a 2 inch arm, and 72 inches is for a 3 inch arm. Exceeding the limit risks self-siphonage of the trap seal.
