VapourBlock Drain Sealer & Trap Primer

VapourBlock is a professional-grade liquid trap sealer designed for drains that sit unused, the leading cause of sewer gas odors in vacant properties. Poured into the P-trap, its citrus formula forms a protective layer over the standing water, dramatically slowing evaporation so the water seal stays intact for extended periods. It remains effective in freezing conditions, making it ideal for winterizing cabins and cottages, rental turnovers, basements, utility rooms and infrequently used commercial floor drains.
