According to their website, the American Backflow Prevention Association is an organization whose members have a common interest in protecting drinking water from contamination through cross-connections. ABPA is an organization dedicated to education and technical assistance. Through its network of regions and chapters, local needs and interests are supported with the resources of the national organization. ABPA is committed to advancing all aspects of backflow prevention for the continued protection of all water users.
The ABPA and Safe-T-Cover have frequently met to exchange information relating to backflow prevention and protecting the water supply. One of the key topics they discuss is RPZ flooding, as is shown in this video of an RPZ discharging water, thankfully while in an enclosure and not indoors. https://www.youtube.com/
