Cast Iron Domed Roof Drain – RD-410

Roof drain Revit family featuring a cast iron sump body with an integrated gravel ring and slotted dome strainer for stormwater drainage systems. The assembly comprises a cylindrical cast iron drainage bowl finished in industrial grey coating, topped with a slotted dome strainer. A vertical perimeter flange forms an integral sediment collar and gravel stop around the central catchment area. Bolted fastening clips secure the removable strainer cap, which features radial drainage slots designed to filter debris while facilitating heavy rainwater discharge into the vertical outlet spigot beneath. Cast metal textures and robust wall thicknesses reflect heavy-duty mechanical engineering specifications for commercial roof drainage assemblies.

The download is a 307 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.

Load this RFA family directly into Autodesk Revit MEP or architectural models to coordinate roof drainage slopes and structural slab penetrations. Place the fitting on roof planes or connect it with vertical rainwater leader pipework via standard plumbing system connectors. The component aids clash detection against roof trusses and ceiling plenums while allowing accurate scheduling across plumbing fixture sheets and stormwater design documentation.

Engineered for flat roofs, inverted roof assemblies, and podium terraces across commercial, industrial, healthcare, and educational facilities. The fixture coordinates with membrane flashing details, insulation buildups, and parapet overflow layouts. Designers and hydraulic engineers frequently specify this unit when detailing primary roof drain systems, secondary overflow drains, stormwater management risers, and drainage penetration details in construction documentation sets.
