Is the foam "tight and concentric"? Will it bear the applied horizontal force of 1/2 the water-filled piping weight within the ZOI? Don't tell Kraig Kirschner - he'll have a stroke.

Just a thought for the Forum: If a CPVC system is encased in a chemically compatible spray foam insulation system, is seismic bracing still required? Seismic bracing and restraint is to prevent "differential movement" between the building structure and the piping system. If the system is held in place by the foam, (with insufficient mass or acceleration to break out of the foam) what more could you ask of a restraint system? Additionally why would this only apply to CPVC? Theoretically you could foam in place all types of sprinkler or mechanical systems and provide the bracing and restraint that way.
