Viking EasyPac Residential Riser Manifold Assemblies are available in sizes 1”, 1-1/4”, 1-1/2”, and 2” for NFPA 13D and NFPA13R residential fire sprinkler systems. The configuration eliminates the need to drain the system before installing the relief valve, while a built in test port allows hydrostatic testing without draining the system. The EasyPac Residential Assemblies include pressure gauges, Potter flow switches, 3-way gauge control valve and 1” drain valve (or 1-1/4” for 2” Manifold). The EasyPac assemblies are made with steel bodies and are available in threaded or grooved connections.
