Expert Insights

The 6-inch drain plug is the largest size in the PSI Urethanes yellow drain plug line, intended for bigger industrial floor drains that require a heavier seal. At 8 lbs, this plug uses its own weight to help maintain seal integrity, reducing the risk of displacement during fluid flow situations. Facilities with 6-inch floor drains are often subject to stricter EPA stormwater regulations due to the higher flow volumes these drains handle, making proper plug availability a compliance necessity. For facilities with mixed drain sizes, stock this alongside the smaller 2-inch, 3-inch, and 4-inch yellow plugs for complete coverage across all drain diameters.

Why Floor Drain Plugs Are Essential

Indoor floor drains connected to the sanitary sewer or storm system are a primary pathway for spilled chemicals and petroleum to leave a facility. SPCC plans and OSHA spill response procedures require the ability to seal floor drains during spill events to prevent pollutant discharge. Floor drain plugs deliver instant, tool-free drain sealing that meets regulatory requirements for indoor spill containment.
