Why Does My Clothes Dryer Vent Tube Keep Clogging?


On a couple of event, in the midst of performing a house inspection, I will ask the home-owner in the event that they’re having hassle with their garments dryer and if it appears to take very lengthy to dry their garments. More often than not they give the impression of being astonished and ask me how I might presumably know that. I am advised that the dryer began out high-quality then simply appeared to take longer and longer to utterly dry the garments, and so they’re getting ready to calling a technician or shopping for a brand new equipment. Then I take them outdoors and present them the harmful situation that exists and the reason for the issue… a dryer vent tube that’s utterly clogged with lint on the exhaust hood.

Not solely does this situation stop the equipment from drying correctly, it is a extreme fireplace hazard. Then I present them the explanation for the clog – a display put in on the top of the exhaust hood. “This display will not be alleged to be there”, I inform them, “and never solely is it a fireplace hazard, however it’s in opposition to constructing code”. To make issues worse, they inform me they beforehand introduced up the problem with their builder, and was advised that the display is required to maintain “critters” from coming into. What a very incorrect assertion. A correctly put in vent may have a flap (damper) on the top that opens when the dryer is working and closes when it is off. This prevents any critter entry.

Having a display, of any sort, on the top of the vent tube is nice for just one factor… stopping lint from venting and inflicting a clog in all the tube, interval”. Anybody who states in any other case is ignorant to the potential hazard in addition to the constructing code. The IRC (Worldwide Residential Code) may be very particular relating to the set up of garments dryer vents and states “dryer exhaust ducts for garments dryers shall terminate on the skin of the constructing and shall be geared up with a backdraft damper. Screens shall not be put in on the duct termination. Ducts shall not be linked or put in with sheet metallic screws or different fasteners that may hinder the movement. Garments dryer exhaust ducts shall not be linked to a fuel vent connector, fuel vent or chimney. Garments dryer exhaust ducts shall not prolong into or by ducts or plenums.”

There are others which are simply as ignorant to the code necessities. On a latest stucco inspection, I occurred to note a severely clogged vent hood. I requested the home-owner my customary query about their dryer and was advised that the tube clogged usually. They’d it cleaned out twice earlier than, and have been on the point of have it carried out a 3rd time. The corporate they used by no means talked about the display on the top of the tube. I would wish to suppose it was simply an oversight and never conveniently missed for job safety.

I additionally seen my neighbors’ newly put in roof with a brand new vent hood put in. For sure it was the unsuitable sort and may by no means have been used for a garments dryer vent. And guess what, it was already beginning to clog and the roofing firm wouldn’t restore it.

The Client Merchandise Security Fee estimates there are 24,000 garments dryer fires every year in the US, amounting to $96,000,000 in estimated property harm. Lack of upkeep and improper installations are the main causes, and LINT is the main materials to ignite. These fires will also be attributable to failure of mechanical and/or electrical elements inside the dryer itself, improper supplies being put into the dryer, and inadequate airflow because of improper set up.

An everyday inspection of your dryer elements and set up materials ought to be carried out as a part of common home-owner upkeep. Make sure to examine your dryer vent and vent hose usually for lint accumulation, and make sure there is no such thing as a display on the top of the tube. If the tube terminates in your roof, make sure to have knowledgeable examine the top for a display in case you’re not snug happening the roof.
