Mandrel testing, also known as a deflection test, uses a metal tool called a mandrel to identify and solve various problems within your sewer lines. Performing this test helps our contractors determine if a pipe has bent under stress and pressure from the soil above. If the mandrel gets stuck within the line, there is a blockage and we can repair or replace the affected pipe. If your line passes this test, we know it is functioning properly.

Mandrel Testing Services Trenchless Pros

Deflection testing effectively detects any problems within your sewer pipes. Although it’s not the most complex method around, mandrel testing is reliable. Here’s how our team does it.

Your contractor will begin by pushing or pulling a mandrel through each pipe. It is a tool, made of metal rods and fingers, that digs through the pipes but stops when it runs into an issue or blockage. Proving rings can then be used to determine if each deflection is within its tolerance. We complete our process in regulation with city policy to help your line get the clearance it needs.

Mandrel testing remains a tried-and-tested pipe inspection method. The service is available for residential and commercial properties. Whether you’re having a new line installed or updating one for your city, the Trenchless Pros team is here to help. Call for a free estimate today!
