About this asset

Grey cast iron backwater valve body Revit family featuring an integrated brass internal threaded seat ring for MEP drainage systems. This drainage component features a heavy-walled cylindrical body finished in a matte textured grey protective coating. Viewed from the top collar, the fitting integrates a precision-machined brass internal retaining ring with stepped recesses and notched alignment slots designed to receive internal check valve mechanisms or threaded assemblies. The cast outer shell maintains a uniform diameter from base to rim, providing robust enclosure for subterranean or in-line wastewater installations. Minimal exterior ornamentation ensures smooth integration within standard piping sleeves or slab penetrations.

The download is a 328 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 family directly into a Revit MEP project to represent drainage accessories within sanitary piping layouts. Align the component with gravity drainage runs, connecting it inline or hosting it within floor assemblies and utility trenches. Verify pipe connector sizes, elevation offsets, and slope parameters in plan or section views to facilitate accurate clash detection against structural slabs and foundation grade beams.

Intended for commercial, industrial, and multi-family residential wastewater drainage infrastructure, this fitting is typically deployed in basement mechanical rooms, parking structures, and sub-grade utility vaults. It coordinates seamlessly with cast iron soil pipe runs, floor drains, and cleanout stations to prevent sewage backflow during surcharge events. MEP coordinators and plumbing engineers search for this component under cast iron backflow preventer, in-line backwater valve, and drainage check valve assembly.
