    So...my house was built in 1967...and at that time it met the standards and codes for building in unincorporated cook county. But today (2017) an inspector noticed a small back pitch in the cast iron waste line going out to the septic tank..(the back pitch is in a 30"section of the 4" pipe)...but the house seems structural fine (no leaks or smell)... when i sell, would the new owner be required to get that up to today's code? Should a good plumber recommend leaving it good enough alone or risk repair the back pitch (which could break the existing pipe(s)..and cause much chaos)?

    "codes" NEVER allowed backpitch, so if it really does have backpitch, it could NOT have met any codes when it was installed. However, if it was correct when installed, then it should be able to be repaired without any "chaos".

    Chicago plumbing code: Is it true that if you have a PVC sewer waste pipe under your floor, you can't just leave it there and install an overhead PVC sewer drain to meet code? I was told by a plumber that even if I have an overhead waste sewer pipe installed to replace the underground PVC, I must remove all the PVC in the floor even though it's cemented in and no one can access it without digging up the cement?

    That seems strange. I have pulled out old cast that was badly rusted through. Anyone from Chicago on here that would know that answer?
