Radiators not getting hot
HELP! No one can figure out how to get my radiators hot... I am not a plumber so bare with me. When I bought my home everything worked beautifully. Had some work done and dry walled basement ceiling (I know really dumb) my main feed and return were literally cut out and moved to a central beam in the middle of the house. I have a Monoflo setup with a plain t on the intake for each radiator and a Monoflo on the return. All the original plumber did was move in the main leaving all t’s To the radiators where there were and simply cutting out length in the main. At the same time each intake and return to each radiator increased in length by like 10ft and on top of it he use 1/2” pex instead of 1/2” cooper..... no one can figure out how to get my radiators hot again! Do I have to cut out our ceiling and replace all the 1/2” pex with 1/2” copper? OR can we replace all the t’a on the supplies with Monoflo as well as keeping the Monoflo on the return? OR can we somehow install a valve on the main between each intake and return to slow down the flow on the main and force the water through each radiator? PLEASE HELP!!
