How do I keep my sweep hose from getting sucked into the vac tube?
The sweep hose should be moving in a gentle sweeping motion. You can adjust its motion by turning the adjustment screw until it slows down to a gentle sweeping motion. Also, verify that your sweep hose scrubber is not blocking the opening at the end of the sweep hose. If it is, move the scrubber so that it will not block this opening.
