What tubing are you using?That 600hr doesn’t make sense when you think of these as continuous duty pumps. That’s 25 days so you would have to replace the internal tubes less than monthly. Doesn’t compute. The manual and app does say 2k hour and the recommmend pharmed themselves say 1k hrs as I posted above. Coralvue recommended aside I’m sticking with pharmed as it’s been working for me at 4K+ hrs.
I would say buy the tubes in short pieces if you’re in a crunch otherwise buy the 2-3 meter bulk and last years.
This thread just reminded me I should replace mine this week. Checking ….4503hrs !!! Per the app
