Spectrapure ATO Spitting

[Furiousreefer]

I recently experience the Spectrapure Ato unit is spitting water And the pump and lines are running like going thur a speed bump. Jerking motion.

If its the UPLC II, its a peristaltic pump and how they work. Each time a rollervsqueezes the peristaltic tubing it squeezes some water out.
