Abstract
Disclosed is a condensate trap system for condensing appliances. The trap includes a cap, a dip tube extending through the cap from a top end to a bottom end, and a canister that houses a cup and has a bottom drain port. An opening along the dip tube proximate the top end is in gas communication with a pressure sensor. The canister's top end is removably coupled to the cap, with the dip tube's bottom end disposed within the cup interior. During normal operation, condensate received at the cap fills the cup, overflows, and exits the canister via the drain port while the opening remains unsubmerged. If the drain port or downstream plumbing is obstructed, liquid rises to submerge the opening, interrupting gas communication and generating a sensor signal indicative of a blocked condensate path.
