While Plumbers are required by code to install Trap Seal Primers to floor drain traps, they must also ensure they do not make connections between the potable water system and any potential source of contamination, without suitable/approved backflow protection. In the case of Trap Seal Primer supply lines, this Cross Connection between the potable water system and the sanitary drainage system has, for the most part, been overlooked with respect to approved backflow protection. I believe this is primarily due to the fact, that a device which provides a practical and approved method of backflow protection for Trap Seal Primer supplies, did not exist.
