I first thought this is caused by a leak, but after running the units at full capacity for 10 minutes, there was no leakage. Also, this is only showing in 3 out of total 20 units. These are Oasis coolers that were installed 2 months ago, and were in good condition at the time of delivery and installation. What could be causing this? And how can I permanently fix it? would cleaning the pipes and painting them with Primer suffice? or would I need to replace? Thanks! submitted by /u/Electrical-Piece-513 [link] [comments]
