My house was built in 2003 in Winston-Salem, NC with the plumbing roughed in for a basement bathroom. The PVC pipe for the shower drain is 1 1/2" diameter. I was told by one plumber that it requires a 2" pipe but this is the pipe that was originally installed when the house was inspected at the time. Now I don't want to dig up the concrete floor to replace it if I don't have to. I know codes vary by jurisdiction and may have changed but before I call the permits office here can someone tell me if this might be true i.e., is this a requirement anywhere you know of?
