Generated explanation

The illustration shows a toilet wet vented through a basin drain connection. The basin discharges through a trap into a vertical pipe that joins the toilet's horizontal drain upstream of the soil stack. The shared vertical section is labeled as a wet vent and specified to be one size larger than normal. Above the basin connection, a dry vent rises and turns toward the stack vent, with its horizontal section sloped back toward the basin branch. The toilet drain is labeled with a slope of 1/4 inch per foot toward the soil stack.
