brwillo Posted November 17, 2015 Report Share Posted November 17, 2015 I have and old Bluebird de-airing pugmill. It was old when I bought it, but worked well. Lately it has stopped de-airing and I am getting lots of bubbles in the processed clay. It is still trying to de-air as the pressure on the vacuum gauge varies. I am hoping I don't have to disassemble it to solve this problem. Insight would be very much appreciated. Thank you! Link to comment Share on other sites More sharing options...
Mark C. Posted November 17, 2015 Report Share Posted November 17, 2015 Do you need a new vacuum pump?-that should be easy to check-just disconnect the line and see how much it sucks? Mark Link to comment Share on other sites More sharing options...

Mark No. I bought it new when I purchased the pug mill. But I will check it again to make sure the line is not clogged. Thank you for answering. Any more ideas?

Sometimes the plastic top that the gauge screws into warps, and needs to be replaced. David . Link to comment Share on other sites More sharing options...
