Aladdin EasyFit Isolator - the quick-fit plumbing isolation-valve for pressurised-pipe
Professionals cut pressurised pipe only as a last resort. Until today, if a plumber needed to isolate part of a 15mm water-pipe system for maintenance or repair there were only 2 options: draining down, or freezing.
Both methods take 30 to 50 minutes and damage the environment through dumping (particularly hot) water, or releasing hydrofluorocarbons (gas-freezing).
