Clearing the Dry Abrasive Hopper
In addition to the Dry Abrasive Hose, another area that an abrasive hose blockage can occur is in the abrasive hopper and/or mechanism at the bottom.
[NOTICE] If your abrasive valve does not look like the one pictured, please contact customer support through our ticketing system in order to have the upgrade sent to you. If you still have the older plug style and try to remove the head in this fashion, it will cause damage to your valve.
5. Shine a flashlight from the plug hole, depress the pinch valve button and observe from the abrasive hopper outlet
a) If light from the flashlight is seen, pinch valve passage is clear and the abrasive clog/obstruction has been cleared
b) If no light is seen, pinch valve passage is blocked and you must continue with the rest of the procedure.
