Dryer vent roof jack

[M Kelekci]

Can this roof jack be used to serve dryer vent?

[John Arnold]

I don't see how it could. There has to be a backdraft damper.

I have one similar to that on my house, but then it is 25 years old.

Ummm ... as far as the question goes "Can this roof jack be used to serve dryer vent?", the answer is 'Yes, it CAN be used for a dryer.'

BUT, it is *not supposed to be* used for a dryer. :)

Jim,

How come Jane didn't get that replaced for you when you bought that home?

Those CB agents. :(

I think it was the sorry inspector that missed it.;)
