Bathroom vent leaks are one of the most common problems homeowners face. This is because the materials that make up these vents are not water-resistant, and they are exposed to a lot of moisture in bathrooms. Bathroom vents can also be damaged by things like chemical cleaners, so it’s important to keep them clean.
The first step you should take if your bathroom vent is leaking water when it rains is to check for any cracks or holes in the duct. If there’s no visible damage, then you may need professional help from an expert who specializes in fixing leaky bathroom vents. After you have ensured that the problem is not with your duct, it’s time to look for a more common cause of leaks in these vents.
The most likely culprit is condensation inside the vent pipe. To fix this issue, all you need to do is increase ventilation by opening windows and using exhaust fans or open doors near bathrooms if possible. The next step would be checking whether any large appliances are causing pressure changes on your bathroom venting system. This could include things like an air conditioner or furnace being turned off too quickly which causes suction within the plumbing lines! All you have to do here is make sure that everything on the line has been depressurized before shutting them down completely for extended periods of time.
