The “UTS-Smoke-Kit-Plus” makes identifying leaks in drains and pipes dramatically easier & cleaner. Potentially identifying leaks in minutes that without the aid of high quality artificial smoke would take hours. Producing a persistent water-based non-toxic smoke. The smoke can travel through hundreds of metres of drains. The unit runs off of water based Aerosols which re-seal after use, so they can be used time and time again until exhausted.
