Hello,
I’m filling my WFP system with rain water only which is between 40 and 45 PPM.
I use 2 DI vessels in series.
I would like to know at which PPM level of the DI vessel n1 I should consider it’s time to change the resin of this DI vessel.
I personally was thinking that the good moment is when the DI vessel n2 begins not be at 0 PPM anymore.
What’s your point of view ?
