Residential riser and commercial riser (Riser manifold assembly) is a pre-assembled, pressure tested riser kit, which is ready for installation right out of the packing box, saving installation cost and time.
The riser manifold normally provides 5 parts in a single assembly for use in NFPA 13, and NFPA 13D/13R: a short length of riser piping, a flow switch, a pressure gauge, a drain valve (Or test and drain valve), and other necessary fittings. Optional Pressure Relief Kits feature a 175 psi pressure relief valve and trim components, which automatically relieve excessive pressure through a flexible hose connected to the manifold drain outlet.
