Hi 

I've got a 300gpd R.o. which about 4 months ago i changed all the filters.

What should the Tds Reading be after the R.o?

Also my 1ltr resin chamber does'nt seem to get the Tds below 002? any ideas why?

Theres a lot of variants,
Whats your tap tds
Whats your mains pressure
1ltr of resin wont last long ( what tds is going into the di )
