Abstract
A conventional bathroom sink has an overflow port and an overflow conduit. A conventional drain pipe for the conventional sink has overflow ports in fluid communication with the sink's overflow port. A vessel sink does not have an overflow port. A prior art drain pipe that does not have overflow ports has been used with vessel sinks. The present invention provides a new drain pipe with overflow ports for a conventional sink and means for covering and sealing the overflow ports in the new drain pipe so that the new drain pipe can also be used with a vessel sink that does not have an overflow port. Means for covering and sealing the overflow ports include an inner sleeve that fits inside the drain pipe, an outer sleeve that surrounds the drain pipe and grommets and hole plugs that that fit inside the overflow ports, where all of the means cover and seal the overflow ports so that the new drain pipe does not leak when used with a vessel sink that does not have an overflow port.
