I see that yours is turned upside down which would force the media to put pressure on the plug and create a vacuum and draw the media out the house as it should...please tell me this is an instruction somewhere that you knew and not some kind of "common knowledge."
HAHA, no its upside down as i was removing all sand and flushed the hoses as i was then using baking soda for the motor. i later had to use sand on the heads as i was using too much soda to remove the paint that was on there.
now to help with your dilemma. i have to change tips on certain medias. if i use soda its a smaller tip. if its sand i use a larger ceramic tip. make sure to check all fittings. if used and the prior person had a poor setup. maybe moisture in lines. that can make mud and clog the connections.
also from time to time i had to shake the container as the sand was a tad moist. i had it laid out on a tarp in the sun for hours but even then was still moist.
kinda like a pressure washer(the gas ones with soap containers), if you want to use soap you can't use 15* tip as its too small to draw soap from the container, but a wider angle tip will work.
