Slow drainage is most often caused by an issue with your private sewer lateral such as offset joints, or blockages caused by roots or grease. For help addressing problems with defective private sewer laterals, please contact a licensed plumbing contractor. Make sure any plumber you hire for a private property sewer emergency is familiar with District policies and programs.
If lateral replacement is needed you may qualify for financial assistance through our Grant and Loan Programs. If neighbors are having similar slow drainage, there may be a problem within the public sewer pipe. For service, call the District at 415-259-2949.
