Hello,
I just installed 4 new radiators in my basement to a water system the problem is only one radiator on the left side of the basement works (get hot). The other 3 on the right side does not?
I did try to bleed them, I noticed that there were no air coming out only water, and they eventually do get hot after bleeding a few gallon of water, but then they'll return to being cold? Can anyone advise?
