Re WP 4821 EndX HEPI H2 Parker Valve Replaced--now in Bleed Mode
Brought down the system pressure, changed H2 Actuator to Bleed mode, isolated H2, switched valve, brought system pressure back to 80psi, checked for leaks. Back on steady ~1000pdt. Will bleed until Tuesday (way longer than should be needed.) Old Valve L176; New Valve L014.
