In the United States and Canada, the raw materials used to make PVC pipe often include heat stabilizers that contain tin. These organotin stabilizers have been tested and found to be safe for use in potable water applications. Studies have shown that one organotin, dibutyltin dichloride (DBTDC), may cause adverse health effects. However, this substance is not present in any of PVC pipe’s raw materials, nor is it formed at any point during pipe manufacture, installation, or use. The bottom line is that:
