In this fire fighting video, we'll be talking about the Inspectors Test & Drain Valve for ZCV Assembly of the wet pipe sprinkler systems in Urdu/Hindi. What is the test valve & drain valve and what does their role in emergency firefighting entail? We'll also be giving you a brief introduction to the valve uses. Finally, we'll be giving you a brief about NFPA codes. If you found anything which is inappropriate then convey it in the comments for my information and rectification in the future.
