After her tragic death, her mother, Nancy Baker, worked tirelessly to advocate for pool and spa safety. Virginia's family and Safe Kids Worldwide actively lobbied Congress to support a law, to require anti-entrapment drain covers and other safety devices for pools and spas. U.S. Rep. Debbie Wasserman Schultz of Florida sponsored the statute, which was signed into law by the President in December 2007.
State Requirements for replacing drain covers in swimming pools and spas
The definition of un-blockable drain in the Pool and Spa Safety Act is:
“A drain sump of any size, or shape, that a human body cannot sufficiently block to create a suction entrapment issue.”
I use the Paramount, SDX High Flow Safety Drain Cover. This universal cover can be used on any style drain and comes in two colors - grey and white.
