Pressure Relief Vaults


Pressure Relief Vaults or PRVs are a great addition to any pumping system or existing water and sewer mains. Romtec Utilities designs and engineers the complete pressure relief valve assemblies. We fabricate the unit with all fittings, piping, PRV valves, pressure regulator valves, reducing valves, control valves, and more. The prefabricated PRV vault is then shipped to your project site for easy installation. Romtec Utilities also provides complete design drawings for the PRV assembly and any electrical design work required for the assembly components.
