Connections between a metal fitting and PVC pipe are made when connecting a cast iron sewer pipe to a PVC drain pipe. Drain pipes from a kitchen or bathroom sink are PVC pipe and run to the main drain that is in your home. Older homes will typically have a cast iron drain that is connected to a toilet. You can use this cast iron pipe to connect with your PVC drain pipe.
