About this asset

Engineered for surge control, this water hammer arrestor Revit family features a rounded cylindrical copper expansion chamber on a threaded pipe tee. The component models a standard plumbing shock absorber assembly designed to mitigate hydraulic shock and pressure spikes in domestic water supply lines. It comprises an elongated cylindrical copper barrel with a smooth hemispherical domed top, tapering downwards into a detailed threaded male connection. This threaded shaft seats securely into a perpendicular branch tee fitting modeled along a straight supply pipe segment. Clean geometric profiles define both the chamber and pipe collar junctions, presenting crisp mechanical detailing suitable for coordination models and service run elevations.

The download is a 266 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 the family into your Revit MEP project to insert it along domestic hot or cold water pipework. Ensure correct alignment with the supply line centerline to establish proper piping connectivity. The component can be placed adjacent to quick-closing solenoid valves or fast-acting fixtures. Standard visual display options allow clear coordination in shaded, hidden line, or realistic views, aiding clash detection against architectural framing and structural chases.

Essential for commercial, healthcare, and residential water distribution models, this arrestor suits layouts requiring hydraulic water hammer protection near dishwashers, flushometer valves, washing machines, and booster pump stations. MEP engineers and BIM coordinators incorporate this unit into plumbing risers, riser cupboards, under-counter service chases, and mechanical plant rooms across hospitality towers, hospitals, and multifamily developments to ensure compliant pipework design and prevent damaging acoustic vibrations.
