Observation
1. JB ABV of phase 50 different type from pervious phase.
2. We found plug spare 3 type on the platform yellow color and Black color and red color then mostly JB which has found water ingress have plugged by yellow plug.(See attached file)
3. Yellow color plug has threaded quite too short (just have 2 threaded) and don’t have rubber seal inside, then possible the point water might be ingress this way.
