Customer Questions & Answers

Can this be used inside a wall to vent a dryer?

Asked by: keeby
I believe the answer is yes it can be used and also that it does meet code requirements for IRC. In regards to the IRC, because this duct is galvanized the thickness should be 0.0157" for 30 gauge. That being the case I guess it depends on your interpretation of the IRC statement of "minimum thickness of 0.0157 inches (0.3950 mm) (No. 28 gage)". I would read that to mean that the 0.0157" thickness is the important part with the (No. 28 gage) simply providing guidance for standard steel.

Can the pipe be cleanly cut or sawed to size?

Asked by: Myster
vahandyman's answer is great, however, I would add that on this gauge of sheet metal tin snips work just fine and are cheap if you don't already have a grinder and cutting blade.

what gauge is the pipe ?

Asked by: bob
30 gauge as confirmed by Master Flow. I would add thought that I believe this does meet code requirements. Because it is galvanized, the thickness should be 0.0157" for 30 gauge. That being the case I guess it depends on your interpretation of the IRC statement of "minimum thickness of 0.0157 inches (0.3950 mm) (No. 28 gage)". I would read that to mean that the 0.0157" thickness is the important part with the (No. 28 gage) simply providing guidance for standard steel. Thus, my conclusion would be that this does meet IRC requirements, hence why Home Depot sells it.

Can this pipe be used to vent a natural gas hot water heater?

I am planning on using it in a chimney so clearance is not an issue.
Asked by: mototriplex
I'm fairly sure this varies by City Building Code. You should check with your City before using it. There usually has to be a certain rise angle and distance from any combustible material.

It was a cinch to install and the toilet fumes go through it like a breeze. I'm so impressed that I'm sure I will buy many more. If you are my friend don't be surprised if you get one soon

I finally got around to changing out the dryer vent pipe that was the foil covered flexible coil type duct. I'm glad I did as I saw how filled with lint it was getting, plus with all those coil ridges it was slowing down the flow out of the vent too. I purchase two of these new metal ducts. Assembling them together was easy once you get them lined up with your thumbs and sort of press them downward together so it catches and work from one end to the other. I had to cut one to size length, trying an aviation snip but I didn't like the finish edge I was getting and it was ark ward in cutting. Thus I did it the slow way with a hack saw and steady short strokes cut it more nicely. Sorry did not have the right cutting tool but with the hacksaw it works but much slower pace. Then using a file to remove the metal burrs and round smooth that cut edge. Sheet metal piping is notorious if you are not careful and get careless will give you oversized paper cuts. Anyway with the proper length assembled together and installed I noticed an improvement in venting and clothes seem to dry faster. Really happy with using this product for my dryer venting.

Though cutting and collapsing the pipe down was trivially easy, it failed to install itself in place and I had to do all the work. Because of this I'm knocking a few stars off.

It is a little hard to work with; some pieces fit together easier than others to make the cylinder. Connections can be a little tricky too, once you tape it up though it works just fine.

This piece of duct pipe is very sturdy and looks great, especially compared to the 25 year-old piece it replaced. Nice shiny finish and the side seam snaps together with a tight fit.
