Reasons Why Water Is Dripping From Your Bathroom Fan

Have you ever noticed that when the bathroom fan is on while you’re showering or shaving, it drips and makes a distinct dripping noise?

You might have also thought, “That’s interesting, but what causes this?”


You might have been tempted to go around fiddling with the fan turning it on/off, or making sure the blades are not cracked or anything similar. But wouldn’t it be easier if you knew why this was happening and how to fix this problem?

Here are some reasons why water is dripping from your bathroom fan:

  • Your bathroom fan is old, and you must replace it with a new one.
  • The air filter may need to be replaced.
  • You may have a damaged fan blade or frozen condenser.
  • You could have a clogged drain or a leak in the bathroom faucet.
  • Dust and other particles have clogged up the vents.

The reasons why water is coming out of your exhaust fans and vents could be easier to identify and fix than you think.

There are many reasons why water is dripping from your bathroom fan, and this article will look at the six reasons why water is dripping from your bathroom fan and ten tips to fix them.

Reasons Why Water Is Dripping From Your Bathroom Fan

Water dripping from your bathroom fan can be slightly annoying, but it can also be quite a concern.

There are different reasons why water might be dripping from your fan, and there are ways to fix it without spending a fortune on a plumber.

Here are six reasons why water could be dripping from your bathroom fan:

1. The Bathroom Fan Is Broken

The Bathroom Fan Is Broken

Bathroom fans are simple devices with only two moving parts: an impeller and a motor.

The impeller is what forces air into your home through the vents, while the motor pulls the air back out again when you turn on your lights or open your windows.

The problem with most bathroom fans is that they’re not sturdy, which means they can break down over time.

When you notice water dripping from your bathroom fan, it is usually because one of these two components has broken down completely or has become loose enough for something to slip between them and interrupt airflow.

When this happens, water will start leaking out of any holes in your ceiling or around any grilles that are attached to it.

2. There Is a Leak in Your Plumbing System

There Is A Leak In Your Plumbing System

If you are getting water from the bathroom fan, there is likely a leak in your plumbing system.

The most common culprits are faucets, tub and shower faucets, toilets, and water heaters. These leaks can range from minor drips to major flooding.

The first step to troubleshooting this problem is to check for a leak in your water supply. This could be due to an improperly installed shower head, an old toilet, or even a broken pipe.

If the drip comes from other parts of the house, turn off all the faucets and plumbing fixtures before continuing with the next step. You can also try adding more water pressure to one area at a time until you find a leak location.

3. The Drain Pipes Have Been Blocked

The Drain Pipes Have Been Blocked

If you’re running a bath and the bathroom fan is dripping water from its base, it may be due to blocked drain pipes. A build-up of hair, soap, or other debris can cause this.

If so, unblock the drain using a plunger or a similar tool. Place one end of the plunger into the blocked drain pipe and push down hard until it reaches its base.

This should dislodge any blockage and allow the water to flow freely again.

4. Your Fan Is Clogged Up

Your Fan Is Clogged Up

The reason why this happens is that water gets trapped in between the blades of the fan and can’t get out.

The blades are designed to prevent water from getting between them, but if there’s enough buildup, then it can be problematic.

If the water is dripping from your bathroom fan, the other likely cause is a clogged air filter. The air filter on top of your bathroom fan is designed to catch dust, dirt, and other particles that get into the air ducts.

The problem is that if you have a lot of hair or pet hair in your bathroom, it can collect on the air filter and cause it to become clogged up.

You can easily unclog a bathroom exhaust fan by removing any lint or dirt caught between the blades and motor housing with a vacuum cleaner or similar tool.

5. Condensation in Your Ducts

Condensation In Your Ducts

This occurs when there is a lot of moisture in the air, which causes it to condense on the metal fan blades and drip down onto your ceiling.

Condensation happens when there is not enough ventilation or circulation in your home. The humidity levels are too high, allowing water to form on objects exposed to heat and moisture, such as your bathroom fan’s blades or ductwork.

You can help prevent this by keeping your house as dry as possible, especially during warm weather months.

You can also try running an exhaust fan in your bathroom or kitchen that will pull moisture out of the air before it can build up on any objects inside your home.

6. The Water Pipes Are Freezing

The Water Pipes Are Freezing

It could be that the water pipes are freezing. This is a common problem in the winter, and it can happen even when the temperature outside is above freezing.

To prevent this from happening, you should ensure that your pipes are not freezing by running hot water through them before turning on your bathroom fan.

This should keep the pipes from freezing and allow proper warm water circulation throughout your home.

How To Fix Water Dripping From Your Bathroom Fan

Ever noticed water drip from your bathroom fan? If so, then you need to know how to fix it.

Here are ten tips to fix water dripping from your bathroom fan:

1. Tighten the Mounting Screws on the Fan

Tighten The Mounting Screws On The Fan

When trying to stop water from dripping from your bathroom fan, you’ll want to tighten the mounting screws of the unit. These screws are usually located on the back of the fan and can be tightened with a Phillips screwdriver.

This will keep water from dripping onto your floor. You can do this by turning the screw clockwise until it’s snug but not so tight that it will cause damage to the fan.

2. Inspect Your Vent Covers

Inspect Your Vent Covers

If you have a bath fan, there is likely a vent cover above it. The vent covers are about 11/4 inches wide and about 2 feet from the ceiling. They keep your bathroom fan in the right place and protect it from damage.

These are typically made of plastic or metal and cover the vents in your shower or bathtub. If you find any cracks or holes in the covers, they should be replaced immediately.

If your vent covers are loose or broken, this can cause water to drip on you when you turn on the shower or bath fan. To fix this issue, tighten them with new ones.

3. Run and Clean the Fan Regularly

Run And Clean The Fan Regularly

Keeping your bathroom fan clean will help prevent it from leaking. Run it for a few minutes weekly to keep the motor lubricated and reduce any debris buildup causing leaks.

To do this, turn off the faucet and unplug it before cleaning it with warm water and mild dishwashing liquid.

Then wipe down all surfaces with a soft cloth to remove dirt and grime hiding in small crevices where water can drip down from an open pitcher or bowl.

4. Use a Hair Dryer To Dry Any Water

Use A Hair Dryer To Dry Any Water

A hairdryer can be used to dry any water that is dripping from your bathroom fan. Just place the hair dryer on the wall and turn it on. The heat from the hair dryer will help speed up the drying process.


Don’t put the hair dryer close to the blades. The heat from the dryer will cause your fan to get too hot, which can damage the blades and cause them to fall out of the motor housing.

5. Check Your Damper

Check Your Damper

If the water leaks from this area, then it may be causing the problem.

You can often fix this by replacing your damper with one that has an extra seal that will seal off the existing one. This will prevent water from entering the fan and causing damage to it.

If the damper on your bathroom fan is not properly adjusted, water will drip from it and down onto the floor below. This can be fixed by tightening the mounting screws holding the damper.

6. Consider Using a Dehumidifier

Consider Using A Dehumidifier

A dehumidifier is a great way to solve the problem of water dripping from your bathroom fan.

A dehumidifier will work by sucking out any excess moisture in your home, stopping the water from dripping down the wall and onto your floor.

Consider installing one near the bath and shower area, so there are no leaks in your house or building.

7. Ensure Your Fan Is Properly Connected

Ensure Your Fan Is Properly Connected

If your bathroom fan is not properly connected and working, it can cause water to drip onto the floor or ceiling. The best way to avoid this is by ensuring that your fan is installed correctly and the water supply line is properly connected.

The next thing you need to do is check whether or not the wiring for your fan is connected correctly. If there are any issues with this, you may need to call a professional plumber to fix them.

They can tell you any problems with the wiring, and if so, they can fix them quickly.

8. Check and Remove Obstruction in the Drain Line

Check And Remove Obstruction In The Drain Line

To do this, turn off the water at the main or shut off the valve outside your house.

Then use a flashlight or a small mirror to look for debris blocking your pipes. Some people also use a long-handled brush to clean out their pipes.

If you find anything blocking your pipes, clear them out so that water can flow freely through them again. Once you have removed any obstruction from the drain line, ensure no other clogs are in the line.

9. Add Insulation

Add Insulation

Adding insulation is one of the best ways to fix water dripping from your bathroom fan.

You can do this by adding extra pieces of foil or bubble wrap to the top and bottom of your fan. Adding these sheets should help you keep the fan drips under control.

10. Change the Position of Your Bathroom Fan

Change The Position Of Your Bathroom Fan

If you notice water dripping from your bathroom fan, it could be that the fan is positioned awkwardly.

In this case, try moving it to a different part of the room. This might help prevent more water from dripping.


No doubt, water dripping from your bathroom fan is a nuisance, but this article has helped you know that this problem can easily be avoided.

Water dripping from your bathroom fan isn’t usually a big deal, but it does make the area around the fan wet and slippery.

While scary at first, it’s nothing to worry about too much. Most of the time, the dripping will stop on its own, requiring only a reboot of the unit and a bit of patience.

These fixes allow you to easily prevent water from dripping from your bathroom fan.
