Looking into replacing my old smelly heater 4" duct pipe.

Is semi rigid metal pipe acceptable substitute? The only other selection I found at the "box" store was some spiral wound "foil" pipe that feels weaker that the original existing.

Also, the sections running to the bedroom and bathroom I was thinking of pulling the new in with the old. Is this a good idea?

My concern is what looks like the existence of nails under the floor that might puncture the pipe as it is being pulled.

I believe it was all open when originally assembled on the "jig."


One of the first things I did when we got our outback in 2011 was to drop the underbelly cover and replace ALL the ducts with ridgid ducts. The spiral wound stuff has lots of resistance to airflow and then wrap it with the thin adhesive backed foam/foil insulation. Airflow went up, and air was warmer coming out of the ducts.
