I just installed an AC unit in my house. Somehow the water is flowing into the bottom pan. This pan has a float to shut off the system when water is present. I took off a duct and baffle and felt the coil housing drain. There is nothing plugging up the drain. I cut the drain pipe downstream of the trap and air vent. There is water draining out through this pipe. I watched that darn thing run for 20 minutes and didn't see any water leak into the bottom pan. Any idea where this water could be coming from? I had the tech back out and we are both stumped. It looks like I might have to disconnect the float and run a second drain line. Any help is very much appreciated.
