This is a fire fighting system tutorial video about "Anti Vortex Plate Assembly" according to NFPA-20 and NFPA-22 in Urdu / Hindi language. It is basic learning detail information about types of firefighting pumps. It is also important for Firefighting/MEP technical staff. Here sharing my experience and knowledge that will be helpful to learn & grow for Engineers & Technical staff. If you found anything which is inappropriate then convey it in the comments for my information and rectification in the future.

I have explained the following in this video:

1. What is anti-vortex plate assembly?
2. Why anti-vortex plate assembly is important?
3. Where anti-vortex plate assembly is required?
4. Installation detail of anti-vortex plate assembly.
5. NFPA-20 and NFPA-22 detail of anti-vortex plate assembly.
6. Disadvantages of vortex for fire pumps.
