A plumbing system, for draining waste material from each of a first draining device and a second draining device into a discharge pipe, includes a first trap in communication with open air and adapted to receive the waste material draining from the first draining device. The plumbing system further includes a fluid conduit providing fluid communication between the second draining device and the discharge pipe and adapted to drain waste material from the second draining device into the discharge pipe. The fluid conduit has a dimension smaller than a dimension of the discharge pipe. The waste material draining into the first trap drains from the first trap into the discharge pipe.
