Used in concealed drainage lines where a cleanout is desired that allows the testing of piping above through the use of an internal threading inside the tee

  • Reduces the chance of mold – due to water spilling inside the chase.
  • Controlled testing environment – provides contractor with effective means of controlling the filling and draining of piping system.
