A blockage in the hose can be determined by inserting the hose into any wall inlet and, while power unit is running, check each additional inlet for normal suction by holding the palm of your hand over the open inlet.

However, if the blockage does not occur when the hose is changed, the blockage is probably located in the tubing system leading to the original inlet.
