We have a 9 year old home the pipes for central vac were installed but never used.
Now we have installed the vacuum and the suction is pathetic..how can we trouble shoot this problem...?
The first thing I would suggest is to see (feel) the suction at the vacuum unit itself. If you can disconnect the tubing from the unit, turn it on and feel for a strong suction. If this is "good" the issue is most probably with one or more of the tubes being blocked or, where they join to another section of tubing (pipe),the connection has separated. This just required gluing and I'd also suggest duct tape over the joint. Check all the connection and this should solve the issue.
thank you for the suggestion. we know the vacuum itself works well..and agree there must be an opening somewhere. as the walls are all finished it will require a camera on a very long line to see where it has blocked or come apart
