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.
Things You'll Need
- PVC primer
- Flexible rubber coupling
- PVC glue
Turn off the water to your home by closing the shut-off valve. Close this valve by turning it clockwise.
Clean the end of the PVC pipe that will be attached to the iron pipe with a clean cloth. Apply the PVC primer to the end of the pipe.
Insert the rubber coupling into the opening on the cast iron pipe.
Apply PVC glue on the end of the PVC pipe with the primer. Slide the end of the PVC into the rubber coupling on the cast iron pipe.
Tighten the metal clamps on the rubber coupling with the screwdriver to seal the coupling to the pipe.
Open the shut-off valve to turn on the water and test the new PVC connection.
Tips & Warnings
- Tighten the clamps on the rubber couplings if you see water drip from the connection.
