Can You Use Pvc Pipe For Bathroom Exhaust Fan

That said there is nothing stopping you from using regular rigid metal ducting.

Can you use pvc pipe for bathroom exhaust fan.

Most exhaust fans have either a 3 or 4 outlet. Use flex vent pipe to go from the fan to the vent pipe pvc. If they did run the exhaust fan into 2 pvc you will not get the air movement you need. Is there any particular type of piping to be used through the attic metal ductwork pvc etc.

Using pvc pipe for bathroom exhaust fan duct. I have to run a length of about 3 meters of duct from the fan to the outside where there will be 2 90 bends. Someone suggested a fernco coupling but a 3 fernco fits perfect on the pvc but it s too big for the fan s exhaust outlet. Also on a long run especially vertical you are bound to have problems like you have now.

You can use round galvanized ductwork or pvc sewer pipe. I was going to use plastic flexduct but i can make the bends bends and some of length using. To connect to the pvc go to an hvac shop and ask for a male 4 to a female connector. Active 4 years 1 month ago.

On 2020 01 31 by mod use 4 pvc pipe as an exhaust duct. I m not familiar with a code that requires rigid ducting for bathroom fans. A cold duct allows condensation of moist indoor air leading to drips from the exhaust fan. Viewed 3k times 1.

Ask question asked 4 years 1 month ago. You will get condensation build up from steam moist air when the pipe runs through a colder area. Otherwise the exhaust duct gets too cold when it runs through the attic. Does anyone know what i should use to connect my bath fans to pvc pipe.

If you need to reduce the 4 to 3 tell them this or just explain what you need. Mass local here unlike dryer ductwork it s not going to be subjected to high heat or a potential for significant lint accumulation.
