    Default How long is to long for a Dryer vent?

    I know not really plumbing, but didn't know where else to put it.

    My gas Dryer is in the basement and the vent goes up 7 feet then makes a 90 degree turn and goes to the wall about 7 more feet. Should I add a fan in the vent line to help with the venting?





    EDIT: Saw the "Venting" category right after I posted. Sorry.

    The 90 degree transition adds an equivelant of 5 feet of restriction in the ducting.
    When you add 7 feet plus 5 feet ( the 90 degree ) plus 7 feet = 19 feet.

    However ... I would suspect there is also a 90 degree elbow coming from the back of the dryer so ... 5 + 7 + 5 + 7 = 24 feet. which should be fine without any additional fan needed.

    Besides ... I wouldn't put any type of fan inside the dryer duct since it will add restriction and will get covered in lint which may cause this fan to overheat.


    Hope this helps.

    Thanks, I've been worried every time I use it.
