I didn't really know what to shoot. The last one is of the 'bad' zone. As you can see, the returns are off. So now we don't have heat at al in those zone. We had a plumber do the original piping. The HVAC folks said it was piped incorrectly and redid the connection from boiler to our water heater. If you want me to shoot something else, just let me know. thanks.
