Individual 225mm/9” sewer and drainage air test pipe stopper, with an expansion range from 219-231mm, designed for use in a standard air pipe test of 100mm water over air.
Please note: A pair of air test stoppers are required to perform an air test
This single air test stopper has both a blank and test end, allowing it to be used on either end of the pipe being tested. The stopper is inflated using a ¼” Schrader valve, and can be deflated using a pull tag on the surface, collapsing into an easily transportable and lightweight shape.
Our sewer and drainage air test pipe stoppers are manufactured and tested to BSEN 1610 - 1998.
