Maintenance type: Observation - No Service Performed
Performed by: Four Seasons
Notes: While maintaining the 1B unit, the technician noted that after "bumping" (i.e. opening and closing) the reducing valve, the boiler filled up. This means that the boiler was not full of water. Some corrosion/gunk in the valve could have been blocking a proper pressure reading.
