Ran into this in a hi rise. Ice machine drain running thru an unconditioned ceiling space on the floor below. Passed that one off to the building engineers. Wish I could tell you how it ended.
water leaks, the guy on top just gives you the run around, to make sure go and look upstairs at his floor, is it dry? if it is, then insulate or cool down your place a little...
How can it be possible that 1/2" insulation isn't thick enough? Maybe if the cast iron pipe was turning into a giant ice ball or something, otherwise I can't see how this is possible. It's just a stupid drain line. Maybe he should just encase the whole damn ceiling with 4 feet of expanding foam.
If you are sure there are no leaks then up the insulation to at least 1" and not just the trap. Run it all the way I the ceiling.

I'm assuming that the water is on the inside of the armaflex? It sounds to me like the pipe is leaking somewhere and pooling up inside of the insulation. Fix the leaks first, then insulate the drain lines if still needed.

You need real plumbing pipe insulation. You might end up having to put some sort of pan under that trap to allow the condensate to re-evaporate into the air.
How thick is the wall of the insulation you used?
Ice water purge causing floor sink and drain to condensate into store below Hey people, Looking for some feedback on a condensate problem. I have a small market that is below a restuarant. All drain lines from the restaurant are exposed in the ceiling of the market. So, were having an issue that when the ice machine purges, all of that cold water sits in the p-trap and the cast starts sweating. Same thing happens with the floor sink. I've done the obvious and insulated the lines with armaflex, glued and siliconed all the seems. Then wrapped with 10 mil tape. Seems all I've achieved is a water tight water vessel? Thought about using heat tape? Also thought about trying one of those heat exchangers for the incoming and purge water to get the temp down. Any ideas?
