Dryer Vent Leaking
Dryers are supposed to dry things, non leave puddles on your floor for you lot to wade through. Water that stands on your floor is a nuisance. It’second likewise a slipping adventure in addition to can damage together with stain the floor surface.
You are non the offset to accept a problem with a leaking vent, as well as at that place are several possible reasons why your dryer vent is leaking. I accept compiled this listing to assist you lot figure out what the effect is too to solve the problem every bit speedily equally possible. So, say goodbye to cleaning up pool afterwards puddle!

Dryer vents can leak if there is insufficient insulation, improper ducting, or blocked ductwork. A vent tin also leak if there is a problem alongside the backdraft damper. Adding insulation, correcting or clearing out the ductwork, or repairing or replacing the damper should solve the issue.
No Ductwork Insulation
A lack of or insufficient insulation for the dryer vent ducting can cause leaking from your dryer vent. This is due to the condensation that tin form inside or exterior the ductwork without insulation. Both of which will effect in H2O dripping from the vent.
A dryer channels hot air (which has skilful H2O retention) into the drum, where it soaks upwards the moisture inwards your wearable. Dryer vents are intended to remove this hot as well as humid air from the appliance and exhaust it outside.
The problem is that condensation occurs when that hot air meets the cooler exterior air too tin no longer agree the same quantity of H2O equally it cools. This is peculiarly problematic for the rattling humid air that is exhausted from a dryer or the bathroom.
When the air loses its capacity for H2O content, droplets grade, together with you lot are going to have a leaking vent.

If you lot’re interested inward a more than scientific explanation of how this happens, yous will discover it inward my article on why bath fans drip.
So, y'all require to protect the vent in addition to keep the air of differing temperatures separate until it reaches the exterior together with can mingle too condense without creating problem for you lot. This is why it pays to ensure that yous install the ductwork amongst proper insulation.
Solution
If your insulation is the problem, and then fixing the leak is every bit unproblematic as adding or replacing insulation on the dryer duct.
Insufficient insulation tin can be a consequence of besides niggling or quondam insulation. Of course, you lot will experience condensation issues if at that place is no insulation at all.
You need to brand sure you accept skilful lineament too the right sort of insulation that is well-fitted on the ducting then that it tin properly role.
You may select to call an proficient inwards for this job, equally it is non equally slowly every bit it may sound to go the insulation to sit snuggly about the ductwork, together with they volition be able to brand sure everything is right.
Improper Ducting
Insulation is non the solely thing that tin can be wrong with the ductwork; the leaking can besides be a event of a problem amongst the ducting itself. There are several areas to expect at when it comes to ductwork. Its length, straightness, together with inner surface all play a part in preventing or causing leaking.
If the ductwork is besides long, has as well many bends, or has a ridged inner surface, and then it interferes with the menstruum of air to the outside.

When ducting has features such every bit these, roughly moist air will rest inward the ducts for besides long together with will cool. This volition inevitably outcome inward condensation as the air cannot hold all the humidity. The condensed water will run dorsum down the dryer duct together with out the vent when it cools.
Excessive bends or a textured surface inward the ductwork volition too encourage lint to build upwardly in the ductwork, which volition campaign blockages that can effect in leaking. A duct that is besides long together with bows volition too promote blockages.
Aside from the above causes, leaking could besides issue from cracks or holes inward the ducting. These interfere alongside the airflow. It is as well allowing condensation to leak out at those sites.
Too many bends, a ridged inner surface, in addition to an excessively long ducting path all contravene the International Residential Code requirements for venting dryers.
Solution
You should consult the manufacturer’second recommended duct length for the dryer. It is possible to shorten the ducting for the appliance by cutting it or purchasing a shorter piece of ducting, only I would suggest you consult alongside a professional for advice if y'all are unsure.
You will accept to supersede the ducting alongside a more suitable fabric that has a smoothen inner surface or if the ducting has get damaged or warped in addition to is no longer directly.
If the vent is leaking H2O because the duct is cracked or has a hole, you lot volition need to supplant the duct to cook the problem properly. Any other solution to a hole or scissure inward your vent is entirely temporary too volition likely need repeated sealing.
It is worth considering that you lot might call for to hire a professional to brand modifications to the ducting for the use of appliance warranties.
Blockages inwards the Duct
Even if the ductwork has been set properly, blockages can take place. If your wearing apparel take started coming out nonetheless damp, this is a adept indication (along with standing H2O) that your dryer vent is clogged.
In a dryer vent, the almost mutual culprit is dryer lint. Lint is the fine material fibers that come up off your clothes when you lot dry them. It can easily make upward inwards the vent in addition to at the exits. Dust can besides be deposited inwards the vent inwards the class of gunk.
If you are the type to forget items inwards your pockets, you may require to inspect your dryer vent for the misplaced gum wrappers, paper, in addition to bits of tissue tin likewise clog up the vent.
Hair is as well a potential, both yours in addition to your pets’. I take a fluffy Canis familiaris, and his fine hair gets everywhere too on everything.
Solution
You tin can remedy a blockage event past clearing out the dryer vent. It may finish up existence a piddling mucky, simply yous should live pool-gratis.
In club to preclude lint from building up together with blocking the vent, you lot should regularly clean out the vent together with the dryer’s lint trap. The lint trap is supposed to grab equally much lint as possible, which volition aid forbid also much from entering the vent. However, this office is impaired when the trap is overly full.

Cleaning out lint from the dryer vent also helps decrease the risk of fires starting equally it manages the sum of lint inwards your home’sec environs by lowering the amount of lint that tin can blow back into your abode through the vent.
Broken Ducts
Broken ducts permit air to escape into other spaces, reducing the pressure inward the ducts. This affects velocity pressure level, which is what moves the air along the ducts. Thus, a broken duct tin issue in air remaining within the duct longer than it should.
Then longer the air spends in the ducting, the more than fourth dimension it has to cool down. Moisture is condensed out in addition to is gratis to drip back down to the dryer.
There are besides a number of dangers linked to broken ducts, like rot, mold, carbon monoxide poisoning, and lint fires.
Solution
The solution to a broken duct is to supervene upon the broken department (patching is non an effective method). You tin can do this yourself, peculiarly if the outcome is amongst the transition duct, or you can hire a professional person. Good options include a full general contractor, an HVAC specialist, or fifty-fifty a roofing specialist.
Faulty Backdraft Damper
A backdraft damper is like a one-style valve, allowing air to menstruum from ductwork to the outside, only sealing against air entering the ducting from the outdoors.
The backdraft damper on the dryer vent is, like insulation, essential inwards keeping the outside air in addition to air from the dryer assort patch it is inward the ducting. If your backdraft damper is faulty, this can outcome in condensation in the ducting together with leads to the dryer vent leaking.
A backdraft damper tin can be faulty due to several reasons:
- It is the incorrect size for the vent.
- It is incorrectly installed.
- Parts of the damper have become damaged, worn, or blocked.
- It is a manufacturing mistake.
All of these reasons tin impact the airtightness of the damper, pregnant that it isn’t performance equally intended too is affecting airflow out of the vent or allowing cooler air into the vent. Both scenarios will, of grade, event inward condensation in addition to leaking from the dryer vent.
You may besides notice a common cold draft or a dissonance coming from your dryer if at that place is an upshot with the backdraft damper.
This is frequently a bigger result alongside dryers that are vented through the roof because rain in addition to snow are more probable to enter the vent.
Solution
If it is a manufacturing mistake, y'all take likely installed a new backdraft damper latterly as well as tin can render the product for a replacement or refund. So, allow’sec expect at the other issues.
It should live tardily to diagnose an incorrectly sized damper equally whoever installed it would accept made some modifications to connect the vent output to the damper. Tape, excessive silicone sealing, as well as the noticeable mismatch between damper in addition to vent are all signs that y'all should be replacing your damper alongside one that fits.
If your damper’s flappers open up inward, it has been incorrectly installed. This is oftentimes a unproblematic matter of cut out the silicone seal, cleaning the damper as well as the vent, too resealing the damper dorsum into the vent inwards the correct direction.
Seals are the exclusively damaged parts of the damper that can live removed together with redone. Mold on the seals or a lint buildup can block the flappers from operation correctly. Replacing the seal amongst a mold-resistant caulk will help, too regularly clearing the lint volition forbid hereafter troubles.
