4. A method for a plumbing parts supplier to reduce inventory and increase profitability comprising the steps of:
selling a kit that includes a sink drain assembly for a first application and means for converting the drain assembly to operate in a second application; and
eliminating from inventory a second drain assembly made specifically for the second application,
wherein the sink drain assembly for the first application is a pop-up drain assembly that has overflow ports and a pivot rod for moving a drain stopper between open and closed positions,
wherein the means for converting the drain assembly is a sleeve that fits inside the drain assembly and covers the overflow ports so that the sink drain assembly can be used in a sink that does not have an overflow channel, and
wherein the sleeve has a pivot rod port through which the pivot rod can pass.
