Trippy you sound happier now. Is it all sorted now? Are you producing pure water yet? What is your lowest tds now? Keep checking it before the di cos if your water pressure is very good you should be getting nearer 10 ppm before the water goes through the di.
I'm just being nosey really.

As said replace the di resin. Also worth buying is another of those 10 inch cannisters and running 2 in tandem. That will guarantee 0 tds. Whereas i reckon it will be 1 or 2 ppm like mine is most of the time.
Once all is set up and working properly it is best to run the RO without connecting to the di vessel for a couple of minutes beforehand. That will squeeze every last bit of resin use out of it all.
