Question 4" PVC Dryer Vent Pipe OK?

I'm re-routing my gas dryer vent piping (about 84" total length with one elbow), and am wondering if there's a downside to using 4" PVC pipe instead of the standard aluminum ducting? (still using a short piece of flex to hook up the dryer, though)
Seems less prone to damage, has tightly sealed joints, and a smoooth interior wall. It would seem easier to brace to the wall, too.
Anybody run into any problems that I should avoid, or is this just another case of ordinary overkill?
Thanks in advance!

Hello OverMyHeadAgain. Welcome to my Gas Appliances forum and our Do-It-Yourself Web Site.

Personally I do not see or know of any reason why PVC cannot be used. It is slightly overkill as you mentioned. The should not be any reasons why using PVC not being allowed in the local codes either.

However, I would not know what your local codes are since codes vary widely from area to area. Calling the dryers manufacturer and the local city office may provide additional insights before you start the project.

If you do install the PVC and it works well, locate your question once again from within this forums list of questions, use the reply button again and update the readers of your question with the completion results and how the piping works.

Doing so helps all the readers of this forum learn more.
