We have a central vacuum system in our house:

Somewhere along the line, something got stuck so various rooms do not have suction.

How can I unblock it? Should I try fishing it out, or will that just jam it in further (I don't know what it is in there). I suppose if I got enough line, I could just keep pushing it till it came out the end.

I'm comfortable / competent enough that if I need to cut into the wall and remove that part of the pipe and replace it, I could do that too - though then how do I figure out where the blockage is?

  • you could reverse the suction (attach a vacuum cleaner on the port while the system is shut off) and see if that loosens the clog Jan 23, 2012 at 18:02
  • @ratchetfreak Interesting; will give that a go this evening.

  • @ratchetfreak A variant of that seems to have solved it (it was a sock). If you post as an answer I'll accept.
