We'll the problem is that i had another r/o hooked up the same way and had no issues although it was less gallons per day.
The new thing is i have now put 20 gallons through it and 2 of the 3 di are now black. So out of 20 gallons that exhausted 2 of my di resins. The tds in Calgary isn't that bad....
Apprently something is not right...
