Dual dome roof drain Revit family featuring primary and overflow drainage bodies mounted to a shared metal roof deck receiver pan. The assembly incorporates two cast metal drain bodies set side by side within a flat rectangular steel bearing pan. Each outlet position is crowned with a heavy-duty, slotted hemispherical strainer dome in a dark finish designed to intercept gravel and debris while maintaining gravity flow. Below the mounting plate, dual cylindrical sump housings provide downward drainage connection collars with integrated clamping collar rings and hardware, enabling secure tie-in to roof waterproofing membranes.
The download is a 297 KB file containing a Revit family (.rfa). Load it into a project from the Insert tab with Load Family, then place it like any other component of its category; it schedules and tags with the rest of your model.
In Revit MEP workflows, place this plumbing fixture family directly onto roof slabs, decks, or roof assembly cutouts. Align pipe connectors to standard stormwater and overflow pipe routing, adjusting elevation offsets relative to structural deck levels to coordinate with gravity drainage runs and secondary overflow discharge points.
Essential for flat roof drainage systems, parapet roofs, and low-slope industrial deck designs across commercial warehouses, logistics centres, shopping complexes, and educational facilities. The dual configuration facilitates code-required secondary overflow protection, pairing directly with internal rainwater pipes, horizontal storm mains, and roof insulation build-ups.
