The Drain-Plus condensate trap is specifically designed for HVAC draw-through (negative pressure) systems. The trap is installed at the end of the condensate lines on the main line and auxiliary drains. The unit maintains a drain seal whether or not condensate is present. Drain-Plus contains a ball and rubber O-ring that form a seal on the condensate line anytime the unit is running. By sealing the condensate line, no outside containments can be sucked into the system. Since the condensate line is not under any negative pressure, water is able to flow unimpeded.
