We carry the top manufacturers of pressure testing equipment for pipes, including Lansas, Cherne, Sklarz and more, to fit your job’s needs. Whether you’re looking for a flow-thru plug (also known as a bypass plug) or a test plug to find a leak location or test line acceptance, United Rentals has rugged inflatable test plugs to help you get the job done. Not using the correct pipe plug can ruin a test, crack pipes and waste resources, so getting the right equipment for the job is important. Inflatable pipe test plugs come in various sizes for temporary sealing and are designed for sewage, water line or any other type of pipe that requires maintenance. Our United Rentals expert technicians service and maintain all our pipe pressure testing equipment to ensure things will run smoothly and reliably on your next project.

FAQs About Pipe Plugs & Testing Equipment

What are pipe plugs?

  • Pipe plugs are temporary solutions to seal and hold pipes in sewer lines, water lines and more to test leaks and water pressure. Inflatable pipe plugs can be fitted into the section of the pipe that requires testing and inflated until snug.

What is the best pipe for water lines?

  • Although PEX, copper or PVC pipes can be used, it is recommended to use a galvanized metal pipe. Galvanized steel has a coating that provides a barrier to corrosion and extends the life of the pipe.

How do you seal a leaking pipe?

  • To stop a leaking pipe, you must first turn off the water supply, then drain the water from the damaged pipe. After that, you have a few choices to temporarily stop the leak before you repair the pipe. You can use a water pipe epoxy compound, pipe wraps, pipe clamps, rubber pipe connectors, plumbing repair tape or repair sleeves.
