Abstract
A plumbing spout is disclosed that discharges a hollow cylinder of water. In one form, the inside of the cylinder can be viewed from the top of the spout. Concentric walls are provided in a spout body to equalize the pressure of the entering water around the spout circumference. An inner wall extends below an outer wall when the fluid discharges from the spout to assist in cylinder formation. The portion of the inner wall that extends below the outer wall preferably also flares outwardly.
