Medical center plumbing repair. Replace the mixing valve in the Pav A water room for the dialysis unit. After the unit was installed, the only way I could get the discharge water temperature above 80* was to turn the cold water stop down. I set pictures and videos of the valve in operations in the customer file. Showing the stops in the picture with temperatures and the hot stop opened and cold turned down, with eyewash running at the time of installation.
