Product Description
The Municipal Pipe Plugging Water Bladder is a water-expandable plug designed to block large drainage pipes and culverts during maintenance, repair or new connection work. Filled with water on site, it expands to seal the pipe interior, diverting or stopping flow without heavy machinery.
It is widely used by municipal utilities for sewer and storm culvert isolation, allowing safe downstream work while bypassing flow through a temporary pump line.
