How2Day: Home Water Filtration Code Requirements in Florida

Residential water filtration requirements in Florida are based on voluntary water quality standards developed by NSF International. This private, non-government agency accredited by the American National Standards Institute (ANSI) works collaboratively with industry, public health agencies and consumers to create equitable, realistic public safety guidelines in over 50 classifications. National Water Quality Association guidelines are also considered code compliant for residential water filtration products used in Florida.

The most common targets for water filtration in residential settings include odor generating or poor tasting substances and deposits. Florida law requires water filtration systems designed to eliminate or control the taste of chlorine, sulfur and other aesthetic contaminants list NSF 42 compliance on packaging and descriptive literature.

Florida law requires that residential water filtration products designed to guard against organic and inorganic chemical contamination note compliance with NSF 53 on product markings and descriptive literature. Products classified under NSF 53 are also approved for effective control of radiological contents in drinking water.

Residential drinking water filtration systems that use reverse osmosis are required by Florida law to have back-flow prevention equal or correspondent to the use of air gap entry to drainage systems. NSF standard 58 or Water Quality Association Standard S-300 must be cited on residential reverse osmosis products in order to be code compliant in Florida.

Florida Law requires that residential water filtration units use connecting tubes according to manufacturer specifications. Tube diameter and fabrication must comply with NSF standards 14, 42, 44, 53, 58 and 61. Check product labeling to verify material specifications and follow manufacturer recommendations.
