Thread: condensate drain trapping
06-28-2005, 01:32 PM #1
I've been perusing through the Residential and Wall of Pride forums and have a question about condensate trapping on condensing furnaces. If the condensate is draining from furnace through 3/4" piping and into a pump, would a drain trap still be necessary? This an upflow system, a-coil on top, and condesing furnace. I haven't seen alot of pictures in the wall of pride section showing drain traps on some 90% units and was wondering what people are doing.
