Step-by-Step Guide on How to Connect PVC to Cast Iron
Step 1: Measure and Cut the Pipes
Measure the length of the PVC and cast iron pipes that you want to connect. Use a PVC pipe cutter to cut the PVC pipe to the desired length. Use a cast iron pipe cutter to cut the cast iron pipe to the same length as the PVC pipe.
Step 2: Prepare the PVC Pipe
Use a PVC primer to clean the end of the PVC pipe that you will be connecting to the cast iron pipe. Apply a generous amount of PVC cement to the same end of the PVC pipe.
Step 3: Install the Rubber Gasket
Slide the rubber gasket over the end of the PVC pipe with the cement. Push the gasket down until it sits on top of the cement.
Step 4: Connect the PVC and Cast Iron Pipes
Insert the end of the cast iron pipe into the rubber gasket. Twist the PVC pipe slightly to ensure a tight seal. Tighten the stainless steel hose clamp around the rubber gasket and cast iron pipe to secure the connection.
Step 5: Test the Connection
Turn on the water and check the connection for leaks. If there are no leaks, you have successfully connected PVC to cast iron.
