Question:

How far can I take a bathroom vent to an exterior wall?

I have a half bath with no exterior wall, how far can I run a flex hose from a vent to an exterior wall? I could run it over the furnace, past the washer and dryer, which are enclosed in a bifold door closet off the kitchen and outside via the same wall the dryer is vented toThis would be about 20 feet - is that too far to go? The other option would be to vent it to the crawl space but that would mean removing part of a wall and redrywalling to do that, I can do that but would prefer a simpler way - its a town house so only 2 exterior walls to work with, and only one that is a viable optionHumidity isnt a problem, the cats litter box is the problem - thanks

Answer:

Make felt out of it, I have not try yet but you can get how to do it from internet.
I have a cat, and I use things like that for crocheting beds for herI also use them for scarves or hats (I live in Michigan, and I wear hats all winter)Using scraps makes them colorful and they will go with anything.
I finger weaved a scarf and then tied all my random pieces to make fringeIt looks very cool!
Use it in a scarf, hat or afghan projectLeave the tails tied tightly and let them hang out on one side of the project as a design elementOr, cut them into 1 inch bits and leave them on the bushes outdoors for birds to use in their nestsLonger pieces, if you garden, can be use to tie up plantsI-cord is good for tomato ties.
I just installed one with a 2.5 foot length of flex tube to my roofBut if you have to install vent tubing that far I would suggest using solid aluminum tubing with as little bending as possibleThe cheap acordian tubing would create way to much turbulance and render the fan very in effectiveIf you use solid tubing you would also be free to install a 3 inline fan down stream of the main bathroom fan on the same circuit for maximum effeciency.
