Hot Water Baseboard Heater Leaking

Options
I have old hot water baseboard heaters in my condo and one of them is leaking. Is there a way to stop the water flow to the individual heater until the plumbers are able to fix it (they won't be here for a couple of days)? I have attached a picture of the left side of the heater, the leak looks like it's coming from a cracked pipe in the far right side. Thank you!

    A picture of the leak or the other end would help. You have to shut off the valves at both ends to shut off that section of baseboard. Hopefully there is a valve at the other end. Otherwise you might try a hose clamp and a piece of rubber if the hole is very small.

    if you have a central heating system then you should have isolation valves on supply coming into condo and return leaving. now saying you should doesn't mean it does but i pretty sure all the condos and apartments i have worked on designed with central hot water heating system with baseboard have had isolation valves in the condos or apartments.

    Thank you for the replies. I have turned off the valves on the unit with the leak and the valve on the unit in the other room and the leak is persisting. Below are two pictures; one trying to show the leak (possibly from the valve), and another of the whole unit

    the heating loop is under pressure. you will have to relieve the pressure at the purge valve to stop the leak. its just left over water in the loop. have you tried to close the cap on that baseboard tee? you can even be able to replace it if it doesnt hold
