  • In this case, test the other outlets closer to the vacuum to gauge their suction too.
  • Most of the time, the outlets closer to the vacuum would have lost suction too. This means the clog is somewhere in the pipe from the outlet closest to the vacuum.
  • There could be cases where the loss of suction is not due to clogs. Then, you might have to go check the vacuum itself.

Ideally, you will have multiple vacuum pipe wall outlets. These outlets are connected to a central pipe that leads to the canister in your basement or garage.
