Hi John,
We don't do TVC or Endo on the NXstage as it has integrated ultrafilter stages. ISO 23500 states micro testing isn't required when these filters are used as per manufacturers recommendations.
We don't sample for metals etc but check historical incoming water quality data as standard pre installation, nothing ongoing. The DI challenge test data they give for the Pureflow, along with cond. measurement  is enough to give me confidence in the system.
They still do it but I think the chlorine test strip is a waste of time, I'd be surprised if these are good enough to show a change at 0.1

Can't seem to get hold of a LINX unit anymore, it was difficult enough before FMC took over. We have had patients come off the system due to having to replace the PAK every 2-3 weeks in our hardest water areas.
