Thanks Matt, but the challenge is that this assembly needs to be capable of being buried. I’m familiar with the ones used inside buildings and we’re not inside a building.

The seismic design category SDC) is “D”. I am being told by the project ME that we should I have a packaged fire pumphouse, discharge exists horizontally through the wall and then turns down to connect to the underground outside of the bldg. The seismic design category SDC) is “D”. I am being told by the project ME that we should have a flexible connection on the discharge side outside the bldg. to accommodate the potential of 8-inches of movement between the pumphouse and underground piping system. I’ve looked around to try and find such an assembly for 8” pipe suitable for an outdoor installation and so far haven’t found such a device. So, my question for those out there in seismically active areas, is this standard practice and who makes such an assembly?
