Water in bathroom fan vent
I’m remodeling upstairs bathroom. I replaced the vent fan. The existing one was old but still ran, it was small but said it was 130 cfm at 3.5 scones. I replaced it with a fan/light combo that is 100cfm. It’s a small bathroom that all four of our kids use so it’s used heavily. When I was moving the 4” flexible vent in the attic around it felt really heavy. I lifted it up at the middle and could tell there was water in it. I kept raising it and dumped most of it from the outside vent. I can’t imagine that is normal. What would cause it to collect like that? It has the louvered vent on the outside and I can see it moving with the new fan on. It vents out the side not on the roof. The 4” flexible vent has the insulated layer on the outside. Not sure if that is necessary. Any thoughts? submitted by /u/ADMOatyMcOatface [link] [comments]
