How should a large galvanized pipe be connected to a smaller PVC pipe?

• A. Female adapter
• B. Male adapter reducing
• C. Female adapter reducing
• D. Male adapter

Answer: (C)

To join a large galvanized pipe to a smaller PVC pipe, you need a transition that starts with a female threaded connection to mate with the galvanized pipe’s male threads and then reduces to the smaller PVC size. A female adapter reducing fits this need exactly: its GI-side uses female threads to thread onto the GI pipe, and its opposite end steps down to the PVC size so you can connect to PVC with the appropriate method (typically a solvent-w Weld or a compatible PVC end). This setup provides a secure seal on the metal side and a proper connection on the plastic side in a single fitting. Using a just female adapter wouldn’t handle the size change, and a male adapter would not properly mate with the galvanized pipe’s threads or with PVC in the way needed for a reliable transition. Similarly, a non-reducing option wouldn’t provide the necessary diameter change.
