The PSP20 is a US CPSP automatic pump shut-off tested to the ASME A112 19.17 SVRS standard for suction entrapment backup. There is no backup for a broken or missing cover as limb entrapment, evisceration (disembowelment), and mechanical entrapment are all still possible. In addition the SVRS standard test protocol does not test for multiple sources of water (dual outlets, skimmers, etc...) and as such devices tested to this standard may not detect blockage at levels described in the SVRS standard.
The Virginia Graeme Baker Pool and Spa Safety Act was signed into law in December 2007 and provides for methods to address dangerous suction entrapment hazards in pools and spas.
