Abstract
A P-trap drainage device having a tubular body and a plurality of internal angled vanes which direct water flow in a circular or whirlpool pattern has a short coupling portion having a coupling thereon, and an extension portion dimensioned and configured to fit within standard sizes of plumbing pipes. In use, the device causes vertically flowing water coming from the drain to the P-trap to “swirl”, increasing the efficiency of flow. The shortness of the coupling portion allows easier use of the device in typically cramped conditions.
Claims12
A plumbing device for use in a plumbing system having standard plumbing couplers and having plumbing pipes having a plumbing outer diameter and a plumbing inner diameter, the plumbing device comprising:
- a tubular body having an interior, an interior surface, an exterior and an exterior surface, and having a first open end and a second open end connected by the passage, and having an axis;
- the tubular body having a coupling section having a standard plumbing coupling thereon, the coupling section having an inner diameter approximately equal to such plumbing outer diameter;
- the tubular body having a vestibule insertion section having an outer diameter approximately equal to such plumbing inner diameter, whereby the tubular body insertion section can be at least partially inserted into such plumbing pipes;
- and
- at least one vane in the interior of the tubular body, the vane set at an angle to the axis of the plumbing device, the vane having a vane first end, a vane second end, and a vane thickness, the vane thickness varying from the vane first end to the vane second end;
- whereby water passing through the plumbing device is urged to rotate as it passes down the length of the interior of the plumbing device.
