The original mission of the 360 Siphon was to provide an odor free, environmentally friendly, healthier living environment for the RV customer for life. Of course it had to be affordable and easily installed in any setting, whether a factory, service center, or the customer's driveway. That goal cannot be accomplished if there is any possibility of a downdraft occurring at the rooftop point of exit for holding tank fumes. Current inexpensive vent pipe caps actually cause that downdraft when exposed to any wind, whether the RV is stationary or mobile. The stronger the wind, the bigger the problem. Since moving air is the culprit, and cannot be avoided, found?a way to make wind a ?friend? instead of a ?foe?.
