Important notes before you begin:<\/p>\n

This self-check assumes the original under-slab or underground sewer pipes have not already been replaced by a previous owner. Even in homes built before 1977 \u2014 or during the 1977\u20131985 transition period \u2014 it\u2019s possible that cast iron sewer pipes were replaced with PVC at some point in the past.<\/p>\n

This tool is designed to help homeowners understand what likely applied when the home was originally built, not to override documented replacement work that may already exist.<\/p>\n

In some situations, confirming the type of sewer pipe below the slab requires additional context. While we do not advertise or routinely perform sewer inspections, we can sometimes help confirm whether a home has under-slab cast iron or PVC sewer piping when it\u2019s necessary to make an informed decision. If clarification is ever needed, we recommend reaching out to us directly rather than hiring another company solely to determine pipe type.<\/p>\n<\/div>\n<\/div><\/div>
