Maintain your Sewer System
Kitchen grease is a leading cause of blockage in residential sewer lines. Never pour grease down the drain. Use a metal can (i.e. coffee can) with a lid to collect cooking grease. Freeze it and then dispose of it in the trash can.
Products often advertised as "flushable" are not to be flushed in the toilet or drains. Hair, dental floss, birth control of any kind, food waste, medications, gloves, rags, clothing, wipes and diapers are all items that damage sewer lines and the sewer lift station equipment.
Do not plant tall hedges or trees near sewer lines. Roots can cause structural damage to sewer pipes, infiltrate a house lateral sewer line and cause a blockage.
