Yes. Pressure relief valves can be reset and VR stamped with full inspection by an authorized valve repair company. Some repairs may be necessary before the valve can be reset. For example, the valve may need a spring change.
Warning: PRVs should NOT be reset above the maximum allowable set pressure of the valve. We’ve seen this happen, and it presents a major safety risk. Before resetting the pressure on a valve, make sure that the pressure you want is within the allowable set pressure for the manufacturer’s valve series.
