Leaking / Overflow Unit in Attic


I noticed that for about a year or so I have water leaking from my AC (Central Air) that is located in my attic. The water looks like it's running (or leaking from a pipe) to my sofit / gutter then dripping from there to the ground outside. Now, I have a leak inside the house (see pictures where the water is coming from - looks like some kind of overflow?). It doesn't leak all the time but appears to build up then flow out for a while. Any advise what may be causing this problem? Thank you!

That main drain line is blocked up and needs to be cleared. usually we use nitrogen to clear drain lines. I'd have an a/c tech come out and put in an evaporator drain float switch in place of that fitting where the water is currently draining from. That way it will shut off the unit and prevent any more water damage in the event the main drain backs up again and water builds up inthe evaporator.

all of that water is humidity pulled from the air, why a/c systems need drain lines.

The pipe is draining into overflow pan. Overflow pan is not draining. Usually drain from pan is on side nearest your gutter. If you can access the point where drain drains into your gutter (outdoors, on a ladder), you can clear it with a long stiff wire or plumbers snake. If your gutters are totally clogged, they need to be cleared.

Not all condensate lines drain into the gutter. Especially not in my area. But good point as far as finding the exit point and snaking back to the unit.

Personally, I would cut the main drain line, cut out the old trap, install a new trap with a union before the trap so that it could be broken apart later (should be done every year) and the drain line cleared. Pvc pipe is very easy to repair/replace. some pipe, fittings and glue and you are back in business.

those are what I use a lot of times JJ, They are EZ-trap brand traps and some (the ones I use) have a float switch that will shut the unit down if they back up of clog.

Thanks all for the valuable information. I need to crawl up into the attic and go up on the roof to do some more investigating. Thanks again...I greatly appreciate the responses!!
