How do you join steel pipe to PVC pipe?

To join steel pipe to PVC pipe, you can use a threaded adapter or a transition fitting specifically designed for this purpose. First, ensure that the ends of both pipes are clean and free of debris. Apply Teflon tape to the threads of the steel pipe before screwing in the adapter, then connect the PVC pipe using solvent cement if it's a slip fitting or a threaded connection if applicable. Always check for leaks after installation.
