Usually you will notice a clog when you connect the hose to an inlet valve and there is no suction.

Step 3: Check the vacuum hose

Unplug the hose from the inlet valve and make sure it is not the hose that is clogged. To do this, put a marble or ball bearing in the hose to see if it will go all the way through.
