Eugene and Victoria Richard of New Hampshire filed a class-action lawsuit on Aug. 5 against Wal-Mart and Rockline Industries, alleging the two companies showed deceptive business practices when selling flushable wipes.

Rockline Industries manufactures Equate flushable wipes for Wal-Mart. According to a report in Legal Newsline, the couple says that despite advertising otherwise, the wipes do not break down when flushed and can cause problems in pipes. The Richards say their septic system leachfield failed, which required them to hire professional plumbers.

The lawsuit was filed in the U.S. District Court Eastern District of New York. Along with damages, it seeks an order declaring the defendants’ practices improper and an injunction requiring the defendants to inform the public about the true nature of wipes.
