Commercial drain service. Pull floor urinal and install new drain assembly and raise urinal so it is level with other two. Serviced two faulty heating controls. Found white and black wires crossed In transformer 4x4 box. I put the wire like the zone is wired in kitchen, I also checked the thermostat’s to make sure they are working. I recommend customer replace power heads in the IT room ceiling. The gym motor runs but the shaft to the valve doesn’t move this is telling me the motor gear is stripped out.
