Pair of 850mm/34” sewer and drainage air test pipe stoppers, each with an expansion range from 844-856mm, designed for use in a standard air pipe test of 100mm water over air.
Each air test stopper has both a blank and test end, allowing it to be used interchangeably on either end of the pipe being tested. The stoppers are 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. Each stopper is fitted with handles on either side to assist with positioning and removal.
Our sewer and drainage air test pipe stoppers are manufactured and tested to BSEN 1610 - 1998.
