Having problems with your Vacuums ?

The upstairs portion of my cetral vac works fine. the downstairs portion never has worked.


Answers :

There are two components involved here, wiring and pipe.
Have someone go to the vac and turn on manually, briefly while you go to an inlet on the lower portion downstairs and open the door. Then shut the vac off.
If you have suction downstairs at this point with the vac turned on manually , your pipes are all connected and the issue is the wiring for the lower level of the house. It will need to be connected to the wiring from the upper level. A good installer will have roughed in the system with the necessary wiring running along the pipe from each inlet. You should find a piece of wire hanging beside the pipe at each of the lower inlets. This low voltage wiring will need to connect to the main line by colored sequence. Your problem may be as simple as a bad splice where the wiring connects to the main line , or a second wire hanging inside the wall behind an inlet which has either come loose or been omitted. Do not unscrew the connection screws at the back of the inlet screws fully where the wires connect as they contain a spring loaded terminal which may fall apart.

If you have no suction, the piping has either not been connected to the pipe from upstairs or your lower piping is clogged. You will need to trace back and find your main floor "drops" in proximity from below , then connect them into the balance of piping for the system, being certain to connect the wiring at the same time. Post back with what you find and if you need more help.
Last of all if you actually have moderate suction on the lower level, but not enough , you may have blockage in the lower line or a leaking valve door upstairs. If clogged you will need to use another vacuum a ad draw the blockage out at a lower floor inlet, generally the one closest to the vac.
Please post to confirm what you have found.
