About 28 million American households claim to experience a toilet clog each month, according to a July 2004 survey conducted for Kohler Co., which found that 27% of 1,000 U.S. adults faced this problem. Of these people, 23% said it happened one to three times per month.
More than 57% of survey respondents said their home toilet was more than 10 years old, which means they most likely require 3.5 gallons of water or more per flush.
