Bathroom Extractor Fan install using rigid plastic duct

In this video I show how I installed a 100 cfm bathroom extractor fan using 4" PVC rigid duct. I chose rigid PVC duct as it has a smooth interior surface unlike the regular flexible ducts. A smooth interior means better air flow which maximizes the effectiveness of the fan to move air out of the bathroom. I show how I ran the duct in the attic and explain how I positioned and cut a hole through the stucco to the exterior for the vent. Disclaimer: check your local building codes, or call a licensed contractor to be sure that installing this type of duct is acceptable in your area. Here is what I used Fan: Delta Breeze 100 cfm https://www.homedepot.com/p/Delta-Breez-Integrity-Series-100-CFM-Wall-or-Ceiling-Bathroom-Exhaust-Fan-ENERGY-STAR-ITG100/308110557 Duct/Pipe: 4" Drain Pipe https://www.homedepot.com/p/Advanced-Drainage-Systems-4-in-x-10-ft-Triplewall-Pipe-Solid-4550010/100135310 Fittings: 4" PVC for example https://www.homedepot.com/p/NDS-PVC-S-D-45-Elbow-4-in-Hub-X-Hub-4P03/100111278 Exhaust Vent: Builders Edge 4" Exhaust Vent https://www.lowes.com/pd/Builders-Edge-Polypropylene-Exhaust-Vent/3819149. NOTE: as discussed in the comments this is designed for new installation where siding is fitted over the flange after installing the vent. I was able to use it as retro-fit due to the thin (1" thickness) of my existing 1970s stucco. For a retro-fit you may need to go with another style vent if your wall is more than about 1" thick.
