new returns - now valves on radiators are clogged

Steamhead (in transit)

that a lot of the boiler's heating ability was being wasted underground. Now that the leaking returns have been repaired, the boiler is cramming a lot more steam into your system than it was sized to handle, hence the strange noises and the sludge being washed out. It may be necessary to have a steam pro look at your system to determine if this is the case or if you have boiler water quatily issues.

installed new returns - now valves on radiators are clogged

Question:
We just recently had some of the return pipes for our boiler replaced. Mainly, it was the ones nearest the boiler, the ones that go underground and then come back up to the boiler. It was good we replaced them because when one of the elbows was taken out of the ground, it had about four or five 2" holes in it, and the pipes were filled with a lot of rust. My mom was the smart one who figured out we had a leak underground based on a continual damp spot surrounding the spot where one of the returns enters the floor of the basement.

But since the pipes got replaced, the valves in my apartment seem clogged. The valves never used to make any noise. The only noise I ever heard from them was a whoosh sound when the boiler came on and the air rushed out of the pipes. Now every valve in my apartment has a gurgling sound.

I checked the new steam pipes and everything seems fine except for one thing that worries me, and makes me wonder if it is the cause of the clogged valves. At the joints of some of the pipes, the plumber put some black gook to seal up the pipes. Could this stuff have gotten into the system and clogged the valves?

I'm very worried because if all of the valves in my apartment got suddenly clogged after this repair, then it means that the valves on the mains in the basement are probably clogged too.

So my question is what could have clogged all my valves suddenly? Is it due to changing a section of the returns in the basement or is that a coincidece? Maybe lots of rust got dislodged when the section was changed, and that's clogging the valves? Or is it the black gook used as a sealant on some of the joints that is causing the problem?

Any feedback will be much appreciated -

Thank you,
Janet V.

job incomplete

get the plumber who installed the piping to come back. his job is not completed until he delivers you a working system. many things could need adjustment.
