Clothes dryer venting. Do’s and Don’ts

Many years ago when I was doing maintenance work for a large property management company, I got a call to look at a clothes dryer that was not working properly. The tenant said that her clothes were just not getting dry no matter how long she ran the dryer. What I found was that the dryer lacked a lint screen, and the flexible vent hose under the house was sagging considerably and had been trapping moisture and lint for a very long time. The more moisture that became trapped in the hose, the more it sagged. The result was that the hose had become completely blocked by an oatmeal-like mixture of lint and moisture. No air could pass through this blockage, and the dryer could not do it’s job. In this case, replacement and proper routing of the vent hose solved the problem. When the proper flow of air is blocked, the clothes dryer has to work harder to dry your clothes, and this could lead to premature failure of the appliance, and in some cases could cause a fire. Whenever you have a home inspection, be sure to ask the inspector to look at the dryer vent hose, and it’s also a good idea to check it at least once a year. 9/1/2004 12:00:00 AM
