We sprung a leak on a baseboard pipe. I have the loop valves closed off, and the drain pipe is trickling out. I want to completely drain that loop, but I'm not sure that the trickling is effective - it may be leaking into the loop from the main supply. We're not planning to use the water heater for baseboard heating anymore, so I'm fine draining the entire thing.
BUT, it also heats our domestic water. I assume it's a unique line through the furnace? Is is safe to open the main drain and drain all the water because the domestic is coming in/going out from the side of the unit? or would that also drain and kill our domestic supply of hot water? And of course it would need to keep running to heat our domestic water. The baseboard loop would be empty, and the pump/thermostats would be turned off too. But would having that empty during heating (heating the domestic line - if it is unique) damage the unit?
I just want to get the water out of the leaking loop entirely, but it doesn't seem like opening the drain valve to that section is getting the job done.
Note: This is an OLD water heater (hence wanting to get it stopped since planning to replace at least the house heating loops)
