Where can you research where your underground pipes are?

To research the location of your underground pipes, you can start by checking your property's blueprints or site plans, which may indicate their locations. Additionally, you can contact your local utility companies, as they often maintain records of underground installations. Utilizing services like "Call Before You Dig" can also help, as they provide information on buried utilities. Lastly, consider hiring a professional locator service equipped with specialized tools for accurate detection.
