First, test the pressure-relief valve located on the top or side of the water heater (Photo 1).
Place a bucket below the discharge pipe and gently lift the lever on the pressure-relief valve to test it.
Matching rupture disc assemblies, also with 400 psig pressure settings, are available to indicate which pressure-relief valve has discharged.

"When you add extra current-carrying paths, less current flows." The same paradoxical behavior occurs in a hydraulic system in which appropriate lengths of tubing and
pressure-relief valves replace strings and strings.
Hansen Technologies sets the standard for engineering excellence with its new reduced capacity pressure-relief valves.
