Floor Drains

Smith Trap Seal Primers and Devices maintain water seals in commercial floor drains to prevent sewer gas from entering the facility through infrequently used drains and fixtures. This range includes active trap primer models that automatically deliver water to replenish evaporated trap seals, as well as passive trap seal devices that block sewer gas escape and eliminate backflow without requiring a water supply connection. Select models feature Labor Saver construction for simplified installation, and select models are lead-free for applications where lead-free compliance is required.
