How To Fix a Leaking Dryer Vent Pipe

A dryer vent can be one of the most essential parts of any appliance in the household. For home safety and reliable performance, a high-quality dryer vent pipe makes drying clothes and finishing daily chores easy and efficient. But when the unit stops working up to its capabilities due to a leak in the dryer vent pipe, you’ll want to address the problem much sooner than later.

Dryer vent parts (connector, pipe)

There are a number of ways to fix a leaking dryer vent pipe, but it mainly depends on the specifics of the required repairs. There could be a crack or a hole in the pipe causing leakage and affecting performance. There could also be a blockage inside the pipe of lint buildup or something foreign that needs to be vacuumed out or removed by hand. Or you could also be experiencing a faulty connection, a damaged or rusted vent pipe, or even a major condensation issue due to the outside environment and inclement weather or climate in your area.

What Causes Leaks In Dryer Vent Pipes?

As previously stated, there are any number of factors that could lead to leaking dryer vent pipes and bringing up the need for repairs, either DIY or by a professional repairman. In addition, the pipe leak could be caused by any number of dryer parts, creating a domino effect your dryer may not recover from if you don’t address it in a timely fashion.

Vent Blockage

• Vent Blockage – One of the most common causes of dryer vent leaks. Lint or fabric fibers may build up over time within the dryer vent pipe, which could in turn block the much-needed flow of air. Blockages can also cause condensation of the hot, moist air released by the dryer and result in a damaging water leak. Most vent pipes that are curved become more susceptible to possible blockages from lint that collects in the curved portion.
• Condensation – Commonly seen in colder climates, condensation results when the warm dryer air is vented to the outside into the cooler air. If you have an improperly insulated dryer vent pipe, this can naturally result in the cooler pipe creating dripping water and harmful condensation.
• Broken Flapper – The outside opening of a dryer vent pipe has a flapper that opens when the dryer air goes through the pipe to find an outlet. If the flapper is not shutting properly when the dryer is not is use, you may find water from rain or snow may accumulate inside. Even worse, a small animal or bird can crawl in as an escape from the outside and cause damage or build a nest that blocks the vent. Make sure to check the flapper from the outside to ensure it is not working right.
• Vent Exhausts Improperly – All dryer vents should have their outer parts directed to the outdoors, or even through the roof. Some homeowners end up having their vent pipes routed to the attic or a garage, which can cause multiple issues. Hot air routed to indoor spaces like an attic or garage will result in moisture buildup that can cause mold, mildew, and water accumulation, which can be damaging to the building structure.
• Cracked/Damaged Vent – Dryer vent pipes can break from being bent too much, moving the appliance against the pipe, accidentally kicked, or simply old age. Cracks or holes in the pipe can lead to condensation that leaks in from the outdoors or possibly from other nearby pipes.

What are the Best Methods for Fixing a Leaking Dryer Vent Pipe?

When preparing to fix a leaking dryer vent pipe, it’s best to do your homework and have the necessary tools and knowledge ready. For fixing the above issues, here are some handy tips for
• Vent Blockage – For dryer vents blocked with lint or fabric buildup, you can use a vent brush to remove the accumulation and repair the flow of hot air through the pipe.
• Condensation – Warding off the possibility of condensation in your dryer vent pipe can be done by insulating the entire vent pipe, along the whole length, in order to prevent temperature discrepancies that create condensation.
• Broken Flapper – Replace the broken flapper as soon as you can, or hire a professional service to do so, in order to keep water, snow, or frost from entering the pipe and causing leaks. If you can’t immediately replace the flapper, at the very least place a screen over the pipe to keep small animals from entering the apparatus.
• Vent Exhausts Improperly – Simply ensure your dryer vent pipe is routed outdoors or through the roof of the home. If this is not the case, you may want to hire a repairman to properly exhaust the dryer vent.
• Cracked/Damaged Vent – The best method of fixing a cracked or damaged dryer vent pipe is to replace it with a new one. You can also try heavy duty heating and cooling duct tape if it’s a small crack or hole, but most experts recommend replacing the pipe to be safe.
