Did You Know?

Sewer backups and overflows are typically the result of grease buildup which can cause property damage, environmental problems and other health hazards. The easiest way to solve grease problems and help prevent overflows is to keep fats, oils and grease out of the sewer system. Never pour grease down sink drains or into toilets.
