We had 8 in the last lab I ran, and we were up to #6 returning them for service as the pump quit on all of them, and this then blew out their cals. They need better QI in the manufacture.

Thank you for the reply. What error message did you get when the pump blew? or was there one?

It was not the pump but the tubing connecting the guts. There would be no detecting happening no matter how much I blew into the tiny hole above the water trap. This meant that nothing was being sucked in thru the vacuum. It made the regular pumps noise, but for naught.

I've experienced the same problem now.

To me, it appears that the plastic on the shell of the case gets dented easily from removing/attaching the water trap.

The dent allows room air to get mixed in with air from cannula, and it always reads low. I've seen one that read high, and that was obviously a different problem.
