Problems with a Dryer Vent in the Garage
Using a dryer vent in a garage can cause a lot of problems, which you should be aware of before installing a vent in your garage. However, not venting the hot air which is produced by the dryer can also cause problems, so must install one in your home or outside garage. Fitting the vent to the outside wall is the best way of ensuring that your home is less vulnerable to moisture and damp. Nevertheless, there are potential problems you will want to monitor after you have installed the dryer vent.
Problems with Leaks
The biggest problem that most people find with their dryer vents is that they is not completely sealed, allowing water to leak through the pipes. Correctly installing your pipes is not always the final solution to this, as pipes can move with humidity fluctuations, and also water can seep along the underside of pipes until a hole is found. Leaks in the garage can penetrate into any electrical equipment located there, such as heaters, so monitor your dryer for leaks.
Problems with Insects
Look for leaks at the end of the vent as well. These can sometimes attract insects into the home, and cause problems with infestations. Cockroaches and flies can easily enter the dryer vent when it is not in use, and then escape through incorrectly joined pipework. If you find that you have an infestation like this, then call pest control, and seal off the pipes using caulking.
Problems with Gases
A significant problem is the location of your dryer vent. If it is anywhere near your central heating flue, the hot air being vented can accidentally heat the gases in the flue, causing them to combust, or turn into more noxious gases. Make sure that your dryer vent is not built close to the flue, and also make sure that you don't use both items at the same time. You should also have a gas alarm fitted near the flue to alert you to possible toxic discharges.
Problems with Mold and Rot
Mold is another insidious problem attracted to the damp of your dryer vent. Mold can be spotted around the outside vent itself, or along pipes. Some mold is toxic, so you should take precautions, and remove all traces of fungus as soon as possible. Mold attracted by the damp can attack nearby wood and concrete supports, so you should also check these out, and replace any damage joists.
Problems with Fitting
A less serious problem, perhaps more of an annoyance, is fitting the vent in the first place. Many people drill a hole through the garage wall, and fit the vent this way, but if your garage is connected to another house, you may have to install the vent above the door. This can mean a lot of expensive pipe work, and also expose cars or bikes below the pipes to water or humidity damage.
