I work for Fresenius and I have a Aqua B system which is about 4 years old. I have noticed when disinfecting the PsP1 gauge located at the bottom of cabinet 2..
I have noticed it is showing 1bar and looking back at my past disinfection it was 2-2.5bars.
It is actually flagging when I complete my TMS pm work order.
I just wanted to get a little education on the pressure gauge and what may be causing the pressure decrease.
I really don't want to call Fresenius since there is so much red tape on getting any answers.
Thanks..

The gauge is actually tied into the RO. So there isn't a pre-filter or anything. The gauge is pretty steady so I don't think it's the gauge.

Product output? A little detail can improve our response. Check the flow diagram, and give us some insight?
