An email came from our building’s management about an HVAC contractor flooding a unit with 200 gallons of hot diluted glycol. It seems most units have two shutoff valves for baseboard heating, but a few have four. The contractor was unaware of this and shut off two, leaving two open. I didn’t even know we have shutoff valves for heating, so I located them today. And there were four, which I’ve now labeled.
