|In response to Re: Dryer Vent Condensation|
: Question: Is there a roof vent design to minimize/eliminate dryer vent condensation during cold weather?
: Background: The last 5-7 feet of my dryer venting goes through unheated airspace in my ceiling where it finally exits at the roof vent. Condensation within the venting is causing water to drip at the 90 degree elbow about 3 foot below the roof vent. The water drippng can be heard for awhile, but stops after about 15-20 minutes of dryer time. I removed a light fixture nearby to verify that the drips occur from the lower elbow seam. I placed some foil/rubber seal tape along the bottom half of the seam since that's as far as I could reach. The drips still occur. The vent cap on the roof is of a standard design: about 12 inches in diameter having a ^ shape, but flatter. The dryer venting was recently cleaned by a chimney sweep. He removed a lot a lint. Most of it was damp which had clogged the venting. He also said it could take a few days/dryer cycles to remove ant remaining moisture in the venting. Thanks for your advice. Dan
