The U.S. Consumer Product Safety Commission collects data on entrapments from suction in suction outlets in swimming pools and Spas. There are currently two national specifications for the testing and marking of manufactured safety vacuum release systems for swimming pools, spas and hot tubs: ASTM designation F2387-04 Standard Specification for Manufactured Safety Vacuum Release Systems (SVRS) for Swimming Pools, Spas and Hot Tubs, and ASME A112.19.17-2002 Manufactured Safety Vacuum Release Systems (SVRS) for Residential and Commercial Swimming Pool, Spa, Hot Tub, and Wading Pool Suction Systems. Over the last two years an electronically controlled system, containing several safety functions, in addition to those specified in the standards, has been developed, tested by an outside laboratory and certified to meet both the applicable standards. This paper includes the results of the testing and changes to the system to meet both the specifications and internal worse case failure analysis. This paper compares and contrasts the two applicable standards, as well as detailing the results of testing both in the laboratory and in the field.
