100mm Mechanical Cleanout Test Plug - DN100 Testite | 115-MTP-100

The Testite 100mm Mechanical Cleanout Test Plug is purpose-built for cleanout testing of drainage systems, capable of handling up to 12 metres of head pressure (equivalent to 40 vertical feet of pipe). Designed in the USA, this plug installs entirely by hand in seconds — no tools, hoses, or gauges required — making it a fast, clean solution for hydrostatic and air testing on-site or during pre-handover drainage inspections.

The expandable rubber gasket compresses to form an air and water-tight seal within the 100mm cleanout access point, while the clear cap provides a viewing window to monitor test media as it drains — eliminating the guesswork and mess associated with traditional plug removal. Plated steel components resist corrosion, and the plug is reusable across multiple test cycles when hand-tightened correctly and tension released prior to storage.
