I have two questions, both regarding old radiators and valves for these.
I've been renovating an old home in new england. Before re-connecting the radiators to their pipes/valves, I wondered if it would be possible to clean out the radiator, with a hose and also adding something akin to radiator flush. Wouldn't that work?
Second, does anyone know a way to detach an old, leaking radiator valve that doens't come loose after repeated squirts with liquid wrench. I was admonished that applying too much force with a large plumber's wrench can break the pipe itself. With temperatures falling, I'd hate to be in the predicament where I had a broken steam pipe coming out of the upstairs floor, which would be pain to repair.
thanks, in advance.
