I need to disconnect and move for a few minutes the compression / expansion tank (aprox. 6-10 gallons) on my boiler / hot water radiator system. I am planning to drain the water in the tank after shutting off the input valve coming from the boiler (with the boiler turned off), unsolder the copper pipe connection,and then reconnect and reinstall the tank (between the joists of the basement ceiling where it is currently).
Question: Do I have to do anything special to make sure there is some air in it or will it automatically on refilling from the system have enough air to fulfill its function?
I already drained 3 or 4 gallons thinking that it was only a holding tank for overflow, and once the flow dropped due to lack of an air intake, I reopened the valve. Since water continued to come out I realized that this was not just a holding tank (I know, this was stupid and I should have asked first).
Second question: By draining this amount, is it likely that I removed all air from the system, creating a hazard once I restart the boiler?
Thank you - regards.
