Can You Use Pvc Pipe For Bathroom Exhaust Fan

Most exhaust fans have either a 3 or 4 outlet.

Can you use pvc pipe for bathroom exhaust fan.

Does anyone know what i should use to connect my bath fans to pvc pipe. You can use round galvanized ductwork or pvc sewer pipe. If they did run the exhaust fan into 2 pvc you will not get the air movement you need. Viewed 3k times 1.

Otherwise the exhaust duct gets too cold when it runs through the attic. I was going to use plastic flexduct but i can make the bends bends and some of length using. On 2020 01 31 by mod use 4 pvc pipe as an exhaust 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.

Using pvc pipe for bathroom exhaust fan duct. Is it legal to have the flex tube vented to a dormer vent but the tube ends 1ft short of the actual vent and not connected directly to it. 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.

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. A cold duct allows condensation of moist indoor air leading to drips from the exhaust fan. Also on a long run especially vertical you are bound to have problems like you have now. To connect to the pvc go to an hvac shop and ask for a male 4 to a female connector.

That said there is nothing stopping you from using regular rigid metal ducting. I m not familiar with a code that requires rigid ducting for bathroom fans. Is there any particular type of piping to be used through the attic metal ductwork pvc etc. By the way some home depot s and lowe s sell this stuff if you know what to look for.
