Can I run the dryer vent hose down into my crawls space and back up into the furnace room then out the wall?
Distance is about 13'. Or should I go straight up through the roof? I'd rather not go thru the roof but will if it is the best option.
Thinking of doing some remodeling and moving things around.

 

Mine is run that way. Just make sure you use a metal pipe not the plastic crap.

A clean out in the middle might help as well.

 

Like he said with the pipe....But since I don't know if this will work for you but I have a junction on mine, in the summer it is blown outside, in the winter I have a lint trap and blow it into the house. being a single person the moister off a couple loads a week is good in this dry climate. Kind of silly to blow hot air outside since I paid to heat it.

 

Mine runs thru the crawl space and dumps outside.

I also have a valve on my dryer that allows me to dump the exhaust air inside the house. I got it at lowes

 

Mine runs through the crawl space to a vent on the backside of the house.

 

About those dryer vents,Keep them clean.Lots of house fires caused by dryer lint igniting.

 

Good point....I use a pipe brush on mine spring an fall when I switch my exhaust......

 

I think going down into the crawl space is a recipe for constant clogging. Low spots collect moisture, which collects lint, and in a few months you have a soggy lint ball clogging the works.

 

a cleanout cover would be very beneficial. Mine is straight once it goes under the house so I can clean from the outside.
Moisture hasn't been a problem that I have noticed.

 

wannadiesel is correct. Low spots collect moisture like a sink trap and will clog up in no time.

 

If I remember correctly from my days of installing dryers (20-30 yrs ago), you were allowed a 25 foot run. And every elbow counts as 5 feet!!

 

Yeah, 4" dryer vent, elbows (90 degree bends) = 5 feet of straight length. Tape the joints w/ duct tape and do not use sheet metal screws to attach. They collect lint and can cause a fire.

If you go with straight pipe put the seam up so moisture doesn't drip thru and slope it a little to the end so it will drain if moisture builds up.

Do not vent into the house if using natural gas or propane!

i think he should go with STRAIGHT pipe, it sounds better

 

And add a smarty to speed up the drying process.

 

might still be a mechanical dryer.
