But I am a plumber and have access to cast-iron sewer lines and long turn elbows. So I’ve been wondering for my first build whether or not a cast iron burn tube with cast-iron riser would be acceptable.
I have looked all over and have never found anyone who actually made the burn tunnel out of cast-iron versus regular steel. Thanks to any contributors.
