A homeowner can find a sewer pipe in his yard by contacting the local sanitation or sewer district and determining where the main sewer line and connection is or by contacting a prior contractor of the home. It is also possible to dig in different parts of the yard to find the sewer pipe by trial and error, however, this method is inefficient.
Unless the homeowner is a professional contractor, it is recommended that digging in a yard for a sewer pipe should be done by those who do it for a living. Someone who is inexperienced can actually do more damage to their sewer lines and property by attempting to make the repair without the help of a professional plumber or contractor. Usually, problems related to sewer pipes involve completely excavating the pipes and then replacing them completely.
