Is the drain problem limited to one sink, bathtub or other single fixture?
• YES: The blockage is in your house. For example if the bathtub won’t drain but the toilet will flush, the problem is between the bathtub and where it drains into the main building sewer line. You then are responsible for taking care of the problem. • NO: If none of the drains in your home will work, the problem may be either the sewer main or your house service that is plugged. Go to question #2.
