Restaurant
Upon allowing grease to enter a drain, the grease begins to accumulate on drain lines. With severe buildup, grease can clog the line causing backups and slow drains. Even with moderate grease accumulation, the restaurants will have problems with odors and drain flies which breed on the grease in the lines. Without proper grease trap maintenance, go the store will have exterior odors and experience excessive grease carryover into municipal sewer lines.
