Floor drain assemblies and floor sinks help prevent clogs and flooding by allowing wastewater to flow into drainage systems. Floor drain grates mount over drain openings to allow wastewater and liquids to pass through but trap larger objects and debris, which may cause clogs. Floor drain bodies, sediment buckets, and seals filter solid particles from water and fluids to prevent damaging clogs to drainage systems. Trench drains direct water to a drainage system or hazardous liquids to a holding tank for proper disposal.
