I tried to find this answer here on my own but I do not know what I am looking for. The other day when we turned the heat on we noticed after it had been on for a while that a few of the radiators had water bubbling around the air valves and the shut off valves. Is this something we should be concerned about it. It has not happened since and I am wondering if this is something normal when the system has been running awhile to heat the house. Thank you for your help.
