I am told that I need to install shut off valves for each loop. I'm just looking for some advice as I have never done plumbing work in my life. Is this something a complete novice can do or should I suck it up and hire a plumber? Do I use ball valves or gate valves? How tricky is cutting the pipe and soldering the new valve? Help please....
There might be other things that need to be checked. There might be other reasons why you are getting air in system, and why it won't work it way out.
As long as you have to drain down the system to work on it , this would be a good time to have a good boiler man look at your system and see what all needs to be changed or repaired. Are there any bleeders in the baseboard radiation? How is the pressure in the system? There is a lot to a hot water heating system, and you could get yourself in a lot of trouble. Paul
