A one-half-inch Type K soft copper pipe routes from a wall supply connection to provide a trap primer for a floor drain. The copper line extends with a slope to deliver water to the floor drain trap, maintaining the water seal. A separate lavatory trap connects above the floor assembly, with piping continuing to the plumbing wall per the architectural plan.
