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?
