Hi all,
I work on a lot of new construction warehouses which have trench drains running the length of aisles of racking of different products, whether it be fruits, milk, soup, anything that can create a spill that needs to be washed down. I am running into trouble trying to get these trench drains vented properly. Currently on this renovation, I am looking at plans (originally drawn by others) that show the trench drains being Circuit vented per IPC 914, but the vents are shown to extend up to bottom of slab, then hold tight to slab, routed to a column, then routed up through roof.
I don't think this is allowed as the vent needs to come up above the flood rim of the drains, correct? The vents are shown as pink in the image above, drain lines are green, and trenches in white. The racking is contained within the white box, with walking access around the outside.
I'm curious as to how others are installing drains like this. I need to rework these drawings to avoid the venting errors and want to avoid putting vents in walkways.
