Just a strait forward video performing a hydrostatic test as per NFPA 25 (2014 edition) on a Fire Department Connection. My municipality still goes off of NFPA 25 (2014), I'm not sure if later editions of NFPA 25 have changed however I doubt it. I know some companies out there use an air test, however this is NOT acceptable as per NFPA 25. NFPA 25 is very clear that it requires a hydro(liquid)static(at rest) test.
There isn't really much to this video it's a very basic test, but since I was doing this work today I figured it was worth uploading a video for anyone that is curious about what is involved for this test/how to perform this test.
If you're interested in how a WET alarm check valve works/all of its trim/components, click on the link below as I used this exact same building/alarm valve in the video.
