The federal VGB Act requires ALL public pools and spas must have a drain cover compliant with the 2007 ASME A112.19.8 standard. The VGB Act also requires that all public pools and spas with a direct suction single drain install an additional device (SVRS, vent line, gravity feed, automatic shut-off, or drain disablement). Approved covers and other devices can be found on the CPSC website.
However, public pools and spas in Florida must also meet the DOH requirements found in 64E-9, F.A.C. Specifically, these ANSI/APSP-16 (previously 2007 ASME A112.19.8) approved covers must also meet the Florida maximum flow rate of 1.5 fps.
In Florida, most public pools/spas are gravity drainage; therefore, they meet the second requirement under the VGB Act. However, there are approximately 7,000 remaining pools/spas that are single drain direct suction. The DOH will be requiring all direct suction public pools/spas to be retro-fitted to gravity drainage to comply with the gravity drainage requirement per the revisions to 64E-9, F.A.C.
