Your caresaver is that quiet? I built a box to go around my Appion so it wasn't so noisy which cut the noise down significantly but a quieter pump right out of the box would be so much better..@rb I was referencing color and quality as circumstantial evidence that there was no oil pollution in the extract. We will be adding a backside scrubber to prevent any catastrophic leakage of pump oil, and we regularly vac still our butane supply to prevent significant contamination.
Honestly I don't think we could go back to a noisy pump like an appion. Probably just stop extracting all together. Hopefully we can get something that will satisfy everyone and remain nice and quiet while doing so.
@naka. Symptoms of a failing appion were changes in the high pitched scream and leaks. There is really no specific warning.
