The owner of this building had an 8" underground pipe burst. Then he took it upon himself to utilize an abandoned existing 6" fire service adjacent to the building. The original 8" fire service was located directly in front of building 'A' and ran directly under the building with the riser located behind building 'A' which continued on to feed two other buildings located behind building 'A'. All three systems were modified 5 years back and had the 3/4" end branch line piping changed to 1" pipe and heads changed out for the 50 year head inspection. Preliminary calculations that I reviewed from previous contractor indicated inadequate water for the current occupancy and that Reliable F1FR were used. I had to loop the existing pipe schedule system and limit there rack storage to 12'. The owner chose to lower the storage height rather than invest in upgrading the system.
