hissing steam radiators
Posted by robwan on December 04, 2003 at 07:56:27:
I had to replace a drippy condensate return pipe in the basement. Since then, my radiators are very noisy. Not banging, but a lot of hissing, enough to wake me up at night. The water level was higher than it should be for some reason (after I replaced the pipe, auto feeder), but I drained some water, and that looks normal now. The drainage was very red. ??? New pipe? Usually it's the typical rust color. Now it's back to the rust color. I'm not sure there's any relation, but I wanted to be complete.
Also, it's a single Input/output system for each radiator, but T's into an upper and lower pipe in the basememt. The top is insulated, the bottom isn't, and the bottom one (I assume the top was steam, the bottom return) was the one that had a few drips and was rusting out, which I replaced.

thanks for any advice. Also, I have one bedroom radiator that never gets hot. is it just blocked with crud? Can I disassemble and clean it out with something? Or do I need to replace it?
