Why Is My Range Hood Dripping Water?

 A range hood is a staple have for your kitchen. It works to filter out cooking odors, steam, and smoke from the air.

They come in various designs and sizes, so it’s important to know what you’re looking for before you try to find one that fits your needs.

Your range hood is drippling water because of Poor insulation that causes condensation build up in the exhaust duct and later air obstruction around the hood. Lack of insulation on your range hood is leading to water leaks.

Start by determining the measurements of your space. This will help you narrow down your options in size and style.

Different units fit over different sized stovetops, so make sure you measure accordingly.

Next, list all the essential features, such as push-button or rotary controls, an indicator of when it needs cleaning, etc.

The more bells and whistles your new range hood has, the more expensive it will be, but they’re worth it if you have them. Sometimes being able to silence the fan is enough.

What Are the Types of Range Hoods?

There are four different types of range hoods: downdraft, ductless, recirculating, and island.

Downdraft range hoods are by far the most common type. They pull the hot air and odors up through a duct hidden under the floor, then vent it outside.

A downdraft uses an electric motor to suck out the air. You can mount these over a cooktop or an island in the center of your kitchen.

A problem with this type of hood is that if you have low cabinets or want to put chairs nearby, there’s no space for air to circulate back into the room.

Thus, you’ll feel less fresh air coming out.

Also, they work best when paired with a cooktop because they don’t work as well with ovens since the heat comes from below, whereas most ovens are on a wall.

Ductless hoods are a great addition to a cooktop if you’re concerned about downdraft issues. They work just like the name suggests.

They pull air through an exterior duct and expel it outside through another opening. This is usually on the other side of your house or out of sight within the walls.

While this type of hood is ideal if you don’t have any open space below your cabinets, putting them in isn’t as easy as other types.

Installing exterior ducting can be very complicated and expensive. So keep that in mind before buying one.

Recirculating range hoods were for those who want their kitchen to remain fresh and clean but don’t want to vent a downdraft or ductless hood externally.

They work by pulling air from the kitchen and filtering it at maximum efficiency. However, they have to have an excellent plugin to work well.

For example, if you’re cooking on high heat and don’t have your fan plugged into a socket that’s working, then the air won’t pull out of the room.

so this type might not be ideal for you. All recirculating range hoods are now required by law to have an activated carbon filter that absorbs odors and smoke particles.

This can significantly reduce how much fine dust you release into the air every time you cook.

Island hoods are essentially what their name suggests: they’re attached to the top of an island.

These are great if you want to save counter space or have enough cabinets below your cooktop to set up a downdraft, ductless or recirculating type hood.

However, these are rarely installed because they’re hard to clean and can interfere with conversation.

Thus, it’s best not to put one in if you want easy access to the rest of your kitchen.

Why Is My Range Hood Dripping Water?

Your range hood drips because of poor insulation. The lack of insulation on your range hood is leading to water leaks.

Every range hood has some insulation lining the inside portion of the hood so that the steam and heat from cooking does not escape into the rest of your kitchen.

If the insulation is faulty, it will essentially be useless because of all the steam and heat that can escape through it.

This eventually leads to water droplets forming on your range hood. This makes sense since you need insulation for there not to be too much heat escaping the unit.

The problem with this is that when you go to wipe down your range hood after cooking.

That same water droplet will roll off into whatever you are wiping it down with or into your hand if you are using a towel or cloth by hand.

This can lead to a very unsanitary surface or hand, depending on what you use it for.

Therefore, consumers give our range hoods high marks because of their ability to stay clean and fingerprint-free, even after years of use.

It also means that they have the best possible insulation possible. This prevents water droplets from forming on them.

If you have an old model range hood in your home, you might purchase one of ours because it could be very similar to what you are experiencing now.

How Do I Stop My Extractor Fan From Dripping?

You can stop your extractor fan from dripping by fixing a washer on the tap’s neck.

This will stop water from dripping out of the neck when you turn it off but still allow air to flow through freely when on.

This solution is not suitable if your extractor fan has a backflow flap. Here, please consult an engineer.

Electricity powers the extractor fans and has a motor that drives a fan blade at high speed, forcing air into your kitchen or bathroom and taking smells and steam with it.

You can change the direction the fan pushes air around depending on where you want to get rid of smells.

These smells may come from under-cupboard extractor fans usually draw fumes up towards the roof, where they’re expelled through a chimney or diverted to the outside.

This is through an external vent pipe. Your kitchen hood fan sucks smell towards it and then pushes them out of your house via the duct.

Air draws into the extractor fan through an inlet grill at the bottom of the unit.

In contrast, damp air gushes out at high speed through another set of grills near the top – usually.

This means that water pools around these vents rather than falling back down into your cupboards below, but don’t worry: there’s a solution for that too.

An extractor fan with a backflow flap fitted will prevent steam from increasing when turning on your cooker ring.

The flaps are easily adjustable, so if you don’t want to cook with steam, you can widen them slightly so that water falls back down.

Your extractor fan draws air in through an external vent pipe.

This is usually fixed to the end of your chimney or wall socket for an outside socket, but if it’s loose.

Then look out for damp patches on the exterior brickwork around this point;

If there are any, get yourself a plumber because your vent is leaking and needs attention straight away.

A build-up of grease in the ducting surrounding your extractor hood could also cause water to pool at its outlet rather than falling back down into your cupboards.

Tighten all joints and check for leaks using a cotton bud dipped in mineral spirit if this is the case.

Will An Extractor Fan Stop Condensation?

Yes, your extractor fan does control condensation, but not as effective as a dehumidifier.

Extractor fans only remove the humidity from the immediate area of the fan, and less than 10% of moisture in a room is because of cooking or showering.

A dehumidifier removes more air from the space and reduces the risk of mold growth.

If you have an extractor fan on your cooker hood, ensure it’s working effectively to prevent smoke from spreading into other rooms.

How does condensation happen? This happens when warm moist air meets with a surface that’s colder than itself, e.g., a mirror, window, etc.

When this occurs, water droplets form on those surfaces until they’re no longer warmer than those surroundings and evaporate away.

You can prevent condensation by turning off extractor fans when cooking and showering.

A dehumidifier minimizes air moisture, which helps prevent condensation from forming on windows, walls, etc.

It draws out moisture from the air to put into water collection trays. Note: If your extractor fan works effectively, there shouldn’t be too much smoke coming back into other rooms.

Does Putting The Heating On Help Damp?

Yes, putting the heating on can help damp. Damp results from hygroscopic salts, which deposit in the plaster of exterior walls.

When the temperature drops at night, warm air leaving a house becomes saturated with moisture.

This moist air condenses on any surface it meets colder than its dew point. I.e., it has a lower temperature or relative humidity.

This includes internal and external wall surfaces, but since most internal surfaces are less exposed to cold overnight temperatures, only the outside walls usually have problems.

Damp patches will show up wherever masonry is exposed to these cold surfaces because condensation occurs during the night-time cooling period when there’s no heat.

Utilities are major energy users in most commercial buildings, but the indoor environmental quality is becoming increasingly important.

You can cut energy usage by reducing heating and lighting levels, improving insulation where necessary, and installing more efficient equipment.

New materials emerge that require less ventilation or have antibacterial properties.

Thus, the challenge for designers is to develop strategies that will allow these objects to accommodate all these requirements without compromising occupant health and comfort.

One way of increasing indoor air quality (IAQ) is through using hygroscopic salts such as calcium chloride and magnesium sulfate,.

Which causes humidity within a building to increase, thus lowering the risk of bacterial and fungal contamination and decay within interior surfaces.

These salts are normally applied to the exterior walls of buildings by spraying, brushing, or dipping.

Once they become hydrated (through absorption of water molecules), increased humidity within a building can benefit IAQ.

One downside to hygroscopic salts is that when they absorb water from the air.

A by-product is that any previously absorbed moisture also becomes released, which can lead to damp patches on interior wall surfaces .

– Particularly common with masonry materials such as brick and concrete having cold surfaces within a building at night time.

To prevent this occurrence, it may thus be necessary to install heating overnight in colder months.

This will help mitigate or prevent condensation from occurring on internal or external walls, potentially reducing the number of damp patches that are likely to occur.


It can frustrate when your range hood drips water or your extractor fan drips. You might have tried a few fixes without success, but don’t lose hope.

There are some quick and simple ways you can stop the leak for good. First, check if there is any food blocking the filter in your range hood – this will usually cause it to leak.

Next, make sure that nothing obstructs the exhaust pipe’s airflow near where it enters the wall cavity (this could also block airflow).

Finally, ensure that there aren’t any cracks or holes on either side of your extractor fan;

These could lead to condensation forming inside, which would then drip out onto surfaces below. I hope you find this information helpful.


Hi! I I faced many questions from customers about different products, and there was hardly any help on the internet. After learning all the things about these products as a manager the hard way, I decided to start a blog and help other people.
