Low pressure in boiler but zone 1 worked still worked while zone 2 did not?
I came to a house for a no heat call. It was a Larrs Endurance boiler. Some how the first floor got heat but the basement was not. In the end it was just low pressure issue, about 10 psi at the time. I would have thought both zones would not work if there was not enough pressure so I was looking for something wrong after the boiler with in the basement zone line. How is possible for one zone to work and not the other with low pressure?
