Question: is cast iron plumbing the same as galvanized?
Answer: Cast iron pipes usually come in 3-4-5' sections with a big bell end on one end and are leaded together where they join. Galvanized pipes are brighter grey (more) shiny looking smooth pipe with 'threaded' ends into a cast or iron elbow or tee, BUT generally threads still show a little. Cast iron is very thick and heavy.
