Camstopper Test Plugs - Nylon

The fast action lever modern design brings many benefits

  • 20 times quicker to install and retrieve
  • Non man-entry retrieval
  • Improved sealing pressures
  • Longer lasting durable pressures
  • Labour cost reductions
  • Allows improved compliance with Confined Spaces Regulations 1997

All new drains and sewers laid in the UK must be subjected to an air pressure test in accordance with BS 8005. For sizes above 300mm in accordance to BS 8000 or BS EN 1610.

  1. Tests should be carried out before back filling or bedding on or surrounding in concrete. Tests should be made manhole to manhole. The tests should be carried out by inserting drain plugs at each end of the pipe and assembling the 'U' Air Kit as illustrated.
  2. Air is pumped in by hand bellows until the pressure of 100mm is indicated on the gauge. Provided the air pressure does not fall below 75mm in a 5 minute period, the drain is deemed to have passed the test.
