Why should we clean our dryer venting system?

In June, 2020, the National Fire Protection Agency (NFPA) issued a report on this topic. Below is a summary of the report’s findings:

“Report Highlights-

In 2014-2018, local fire departments responded to an estimated average of 13,820 home structure fires per year in which dryers were involved in the ignition. These fires caused an average of seven civilian deaths, 344 civilian injuries, and $233 million in direct property damage annually.

One-third (32 percent) of dryer fires were caused by a failure to clean. This appears to be mainly lint build-up, as 27 percent of dryer fires started when dust, fiber or lint ignited.

Many years ago I had trouble with our dryer. I kept adding dryer time, but the clothes kept coming out damp. I cleaned all the vent pipes, the dryer itself, everything I could think of. So I called Sears. The serviceman noticed that the lint screen was clogged with soap. He asked me if we did a lot of our laundry in cold water, yes, we do I replied. He explained to me that the soap, which was not totally dissolved in the cold water clogged the lint screen in the heated dryer. And, that is why our clothes were coming out damp…FYI Guys!!!!!

What does a poorly installed vent pipe look like?

The vent that comes out of your dryer should be vented to the outside of the house. The vent itself can be bent or constricted as you can see form the images below. Restricted airflow is dangerous.

How about a properly installed venting system???

The best venting material is galvanized metal pipe, galvanized metal elbows held together with screws and aluminum tape.

Vent piping materials:

The market offers various type of venting pipes, but we suggest the galvanized steel because it’s smooth and it won’t catch the lint. The next best is the corrugated aluminum pipe. The vinyl isn’t even allowed anymore by code and the tin foil type is thin and is prone to rip and catches a lot of the lint.
