Re: How do you remove radiators for repair?
possibly. however, that is how you learn. you will need to shut off your boiler or heating source and then drain the sytem at the lowest point. then go the the highest point and crakc open the unions on the radiator. there should be a union fitting on both the inlet and outlet (supply and return) pipes of the radiator. use your large sized adjustable wrench and another for backup. loosen the union and be ready for the water.
this is why alot of walls behind toilets and radiators never get that touch paint.
Process of elimination. Good luck.
