These inflatable devices are utilized to temporarily block the flow within pipes and drainage systems. For example, during plumbing repairs or when conducting pressure tests on newly installed lines, these tools provide a secure seal to isolate specific sections of the system.
Their application is crucial for maintaining system integrity and preventing potential water damage during maintenance procedures. Historically, alternative methods were cumbersome and less reliable, leading to significant downtime and potential complications. These tools offer a more efficient and dependable solution, minimizing disruption and ensuring accurate testing.
