 Paraffin plug in the tubing? More often than not that was caused by
over filling the paraffin containers. The vacuum pump will pump for
three minutes and does not sense when the retort is full or empty
completely. The tubing fills with paraffin and hardens. I believe the
heating element is between retort chamber and the rotary valve, so the
tubing is at room temperature. We have found that a little less solution
is better than more. Stay beneath the lines, the lines are our friends.

 Water is part of the fume control system. Do we like our VIP's? We
have two, year old VIP5s, one VIP 2000 and five VIP 3000s. We just had
to learn how to care for them.
