well you really don't have a choice...if you put a dip in exhaust piping ...it will collect water at some point...then what? ben srI need to vent my bathroom fan through my crawl space (15 feet wide). Im worried about the sloping of the duct, can you look at the attached picture and see if I'll be okay?
What worries me is that my upstairs bathrooms vents connect to roof vents. Sometimes the duct falls off of the vent and then its hanging in the attic. So the duct goes about 5 feet up, then 5 feet down (because there is a support halfway up). When this happens, I get water that runs back down and ends up on my bathroom ceiling. I was told this is because the line goes up then down. So now I'm worried about doing this in my basement.
BTW, I really don't have another choice. I *could* go through the basement wall, but the wall has ceramic tile all the way up to the ceiling and I really dont want to mess with cutting it out. I'd rather just go up and over the wall.
Thanks!

Because going one way would end up on the front of the house (which I don't want for cosmetic reasons), and going the other way would end up under the deck out back. And I'd really rather not vent the bathroom right under the deck where people sit so they have to smell bathroom odor! My drawing has it going out the side of the house where all the utilities are.Why can you not run it the other way between the joist?
It's cinder block wall, but there is only 3/4 of a block showing outside. That would put my vent in the ground, almost. So any snow would completely block the vent.2. If you have to run it as shown, why do you have to go back up and out through the band joist? Why cant you go through the foundation? Is it poured concrete? Just run 3 or 4 inch DWV PVC sloped at 1/8 inch per foot out to the wall, punch through. Grout in a steel nipple with epoxy cement, then go through with the PVC. Put a street L facing down on the end and put 1/4 inch screen in end to keep out creatures. Stuff backerod and sealant around pipe
Okay, metal or PVC pipe is fine with me. But am I still going to have a problem dipping down and back up if I use metal or PVC?corrugated flex is no good for this, as moisture will build up in the pipe.
I'm curious what the experts say about this...... and going the other way would end up under the deck out back. And I'd really rather not vent the bathroom right under the deck where people sit so they have to smell bathroom odor!
