I tried it with the valve at the bottom of the tank wide open, partially open and nearly shut - all it did was clog up after a few seconds. I tried bigger and smaller nozzels - no change - clogged after a few seconds of operation. [Reply]   [No Email]

Guys on here say not to use playsand so I don't can't remember the reason think it was something called silicosis from the dust. [Reply]  [No Email]

The only time it seemed to work much at all was when I completely removed the valve on the end of the hose and sprayed with a 1/4 opening. [Reply]  [No Email]

Silica sand should not be used without a breathing respirator that is rated for silica dust. I use silica sand in my cabinet blaster, but it has a shop vacuum attached to it. [Reply]  [No Email]

It had 3 valves on it when O got it and yep had the same problem. I removed the valve at the bottom so it now has only the 2 upper ones and as long as the sand is good and dry and the air is good and dry it does ok but you do at times have to shake it some to keep it going [Reply]  [No Email]

Only till the sand starts to flow. Usually have to mess with it a couple of times Last time I used mine I ran it without the valve at the end of the hose cause I was tired of unplugging the hose. Seemed to work just as well. Someone else mentioned on here to use coarser abrasive in the cheap units cause it flows better. Have not tried that yet. Still think waterblasting off the pressure washer is easier and less messing around. You may not have a pressure washer or want to deal with the water mess. [Reply]  [No Email]

Screen some sand then spread some out in the sun to dry then try to see if that makes a difference. Jim Will [Reply]  [No Email]
