Thanks Eddycurrentguy.
I live in Toronto, Ontario, and am using the NFPA 13 handbook, however I am finding it difficult in how deep the pipe should be. It states in NFPA 13 that the pipe clearance shall be provided to prevent breakage of piping due to building settlement, however it does not...
Does anyone know how deep underground piping (for sprinkler systems) should be when it passes under a building foundation? I am having difficulty finding this information in NFPA 13. Any help on this would be greatly appreciated.
Thanks
