Fixing an Exhaust Fan that Drips

Fixing an exhaust fan that drips can be a tricky activity, but it is not difficult. Instead of complexity, this job simply requires time and attention to detail. The exhaust fan itself is meant to remove odors in a room, but also general moisture. Because the moisture is sucked through its vacuum, the exhaust fan may have a buildup of moisture, which could “infect” other areas. Another way moisture could end up in places it should not id if the exhaust fan’s tubing sprung a leak, and the moist air that is supposedly running through it may be escaping, practically spraying the proximate area of the leak.

  • Duct Tape
Step 1-Jumping in

The first step requires plenty of patience, because you will need to follow the exhaust fan’s tubing with your hand. Feel up the tube to see where there may be some escaping air. For the most part, you will be able to note water dripping to indicate a tear in the line. However, there may be other tears that are still too premature to accumulate a whole water droplet, and since you are already in the neighborhood, it is highly suggested to check for other leaks. Note not to turn off the power. Although it sounds dangerous and can be quite intimidating while working with the power on, you will need the power to be on so that you can feel the line in action. If the power is off, then you cannot feel the air escaping through any holes since there will not be any air running through the line.

Step 2-Fixing Leaks

With just the use of duct tape, you can prevent mildew, mold, and any other serious potential hazard related to moisture that is built up in the fan exhaust. When you find a leak that is either spewing out water or just air, secure the leak by patching it up with duct tape.

Step 3-Knowing when to Quit

Although the duct tape can and should hold for a very long time on the leak, if you have more than a handful of leaks, you may want to replace the line entirely. Note, if you have one too many leaks proximate to each other, than duct tape may not be able to help. The reason why leaks that are too close together are more difficult to deal with is because the moisture from one leak could build up with another nearby leak on the same piece of tape, weakening the tape, and eventually you will be back in square one. So, if there are one too many leaks close together, simply replace the line.
