Default More RODI Help

Getting frustrated here.

Had phosphates in my RODI water a few months back so I ordered new filters, membrane and DI resin... Had been a while. All installed about 6 weeks ago.
Still having PO4 issues so I measured again and it was 0.10ppm on a hanna checker. Lines were flushed clear before taking sample water.
RODI is 4 stage. 1 micron sediment, 1 micron carbon block, RO membrane, then DI resin. I talked to the city of Nanaimo water manager they only add chlorine to our water, where we live should rarely see over 0.5ppm. They dose chlorine to 1.7ppm but we are near the end of a large distribution run. For the same reason turbidity should be low where we live as well, he went into seasonal specifics but lost me quick...

oh... and inline TDS meter reads 10 to 12(guessing ppm) going in and 0 coming out. Says it came factory calibrated.

Am I missing something really obvious here? Any suggestions would be appreciated.

Thanks. Jesse
