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 –  ratchet freak Jan 23 '12 at 18:02
    
@ratchetfreak Interesting; will give that a go this evening. –  vcsjones Jan 23 '12 at 18:11
    
@ratchetfreak A variant of that seems to have solved it (it was a sock). If you post as an answer I'll accept. –  vcsjones Jan 24 '12 at 19:26
