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 may probably 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, they usually’re getting ready to calling a technician or shopping for a brand new equipment. Then I take them outdoors and present them the damaging 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 rationale for the clog – a display screen put in on the top of the exhaust hood. “This display screen will not be imagined 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 difficulty with their builder, and was advised that the display screen is required to maintain “critters” from getting into. What a totally incorrect assertion. A correctly put in vent can 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 screen, of any sort, on the top of the vent tube is sweet for just one factor… stopping lint from venting and inflicting a clog in the complete 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 concerning the set up of garments dryer vents and states “dryer exhaust ducts for garments dryers shall terminate on the surface 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 related or put in with sheet steel screws or different fasteners that may hinder the circulation. Garments dryer exhaust ducts shall not be related to a gasoline vent connector, gasoline vent or chimney. Garments dryer exhaust ducts shall not lengthen into or by means of 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 normal query about their dryer and was advised that the tube clogged frequently. They’d it cleaned out twice earlier than, and have been on the brink of have it performed a 3rd time. The corporate they used by no means talked about the display screen on the top of the tube. I would prefer to assume it was simply an oversight and never conveniently ignored for job safety.

I additionally seen my neighbors’ newly put in roof with a brand new vent hood put in. Evidently it was the improper 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 brought on by failure of mechanical and/or electrical components throughout the dryer itself, improper supplies being put into the dryer, and inadequate airflow on account of improper set up.

An everyday inspection of your dryer parts and set up materials must be carried out as a part of common home-owner upkeep. Remember to test your dryer vent and vent hose frequently for lint accumulation, and make sure there isn’t any display screen on the top of the tube. If the tube terminates in your roof, make certain to have an expert examine the top for a display screen in case you’re not snug occurring the roof.
