Black Friday busiest day for plumbers

CINCINNATI, Ohio - U.S. plumbers say Black Friday, the day after Thanksgiving, is their busiest day of the year, thanks to holiday meals and guests. Big holiday meal preparation and cleanup mean lots of grease and food go down the kitchen drain. Holiday guests require additional clothes washing, showers and toilet flushes, straining household plumbing. ?Often, a house already has partially clogged drains that aren?t noticeable until holiday guests arrive and overwhelm the system,? Paul Abrams, a spokesman for Roto-Rooter, a 24-hour plumbing company, said in a statement.
