In your house you have lots of drain line running from the toilet, sink, tub, washing machine etc.. Most are copper, galvanized, or cast iron. If you don't have PVC you are more likely to have clogs, leaks, and broken pipes. Trying to do the job yourself can be dangerous from the sewer gas since it can make you sick. We already have the right tools, parts, and experience to do the job to state plumbing code.
You will only see this once.
