ABC NewsA confidential industry study obtained by ABC News warns that popular drain covers found in millions of backyard and public US pools have been incorrectly tested and that their use could "result in serious injury or deaths." While the report has not yet been made public, one of the makers of the drain covers has quietly asked retailers to stop selling one of the covers to new customers.
The American National Standards Institute (ANSI), a national product standards certification group, found that earlier test results for four drain covers from three brands, Aquastar, Paramount, and AFRAS, were unreliable, and that the results of more stringent tests for swimmer entrapment were "cause for immediate action."
At least 11 people are known to have died from entrapment from heavy suction by pool drains since 1999, including 7-year-old Virginia Graeme Baker, whose death by drain entrapment in 2002 spurred the passage of a pool safety law named for her five years later. The Virginia Graeme Baker Pool and Spa Safety Act created stricter anti-suction standards for pool drain products.
The ANSI-supervised re-test simulated the blocking of the drain cover by a body for three of the covers, and "hair entanglement" for the fourth cover. Results for three of the four drain covers deviated from previously published results.
