Why does my extractor fan drip

From the description sounds like your unable to get exit of the ducting lower than the fan, so condensation will always need some where to go. Either if you have external wall fit fan into bathroom, or try Positive Input Ventillation unit which fits in loft and will vent the entire property.

Hi, I have some tiles that have popped off on the vertical side of a bathroom window recess. I've remove all the tiles along Hi Folks, I hope to glean some advice before getting an electrician in to install a bathroom extractor fan. Any advice would be Hello, Following a water leak into my bathroom, from the flat above, our extractor fan stopped working.

I had this replaced Ask a tradesman. So far we have tried: 1 Fitting a new extractor. This is the only way to stop condensation running back down the duct line and into the fan. Liked There are a few solutions i can think of that will help prevent this. Chris, Whittaker Electrical. Just a thought. Hope that helps. When you cook on a stove, your high school chemistry and physics teachers are grinning somewhere. As you may have learned in class all those years ago, the process creates vast amounts of water vapor as you heat food and boil water.

When you heat up or fry meat, you also melt grease. Some of it gets converted to vapor, and tiny droplets of the grease can hitch a ride on some that vapor as it floats up from your stove. This is why exhaust fan manufacturers have very explicit requirements for both the minimum diameter and maximum length of the exhaust pipe that connects your fan to the outdoors. This is why most high-quality exhaust fans have high-speed fans.

The fan is trying to blast the water vapor outdoors in just a few seconds, rather than allowing it to meander through the exhaust pipe. First inspect the damper on the outside. If water drips from the bathroom exhaust fan, the damper that normally controls the flow of air through the pipe may not be working correctly.

It should open only under pressure from the warm air to let it out, and remain closed the rest of the time. Another option to control water drips is insulation on the ventilation pipe.

Replace or reposition fan. If the fan is right over the shower or bathtub, it gets the air at its warmest point, which means the air will condense very quickly in a chilly ventilation pipe. Run the fan effectively. You should also try to remember to run the fan we know, the sound is annoying!

This melted snow then finds its way into your home through a lousy roof vent or through your roof itself. Melted snow will essentially give you the same issues as rainwater. There can also be a broken damper that is allowing this water into your home. If you tried to save money by buying the cheapest fan available, that fan might not be up to the job. If you have a huge bathroom or the air must travel through a lot of ductwork to reach outside, you will likely need a stronger fan, or you may need to place your fan or vent somewhere else.

The bends in your ductwork also play an integral part in proper ventilation. You should take a leaking bathroom fan seriously. It is best to take care of any leak as soon as you can. As the longer the fan leaks, the more likely it can cause damage. This would depend on your insurance policy but in most cases; homeowners insurance will only cover damage from a water leak if it was sudden or accidental. But the damage caused by mold is usually not covered because a water leak brings on mold over time.

Something like a pipe bursting would be sudden and should be covered. But in most cases, water damage from a leaking bathroom fan is not covered. I was taught carpentry at a young age by my father. After highschool I worked with my father as a Union Carpenter for six years.
