i've got 2 leaks in my black pipe connections in my primary loop, i'm losing 16 ounces of water every 24 hours from my pressurized system,i have the pressure reducing fill valve open for make up water,it would be a real pain to take it all apart to get to the leaks to fix them especially now, just wondering if i should be worried about adding new water to a closed system all winter. if not its not a big deal where the leaks are in my basement ,i was hoping they would rust shut but its been over a month, any way to seal them without taking it all apart
