My incoming pressure is 70psi, temp is 63.3
Maybe that helps you judge against yours... |

My last thought is that it could be that the resin is getting old. I know the unit is new to you, but if the manufacturer filled the canisters in advance and then the unit sat in their warehouse a while, it could already be somewhat depleted. The resin starts to deplete as soon as it is exposed to air. This is a bit of a long shot, but could be an part of the problem. I'm sorry I couldn't help you solve this, but I am out of ideas. Maybe someone else will chime in some other thoughts.

The Di was in a sealed bag and I had to fill the canister myself. I checked on line and the ro membrane should givery a 97% rejection rate. It's summer here and most days for about 2 months it's been 20 plus c. I've been running the unit again tonight and it dropped to 2ppm.

Just an update if anyone is interested.
I have spoken with the manufacturer and they are sending me out new di resin and ro membrane as they agreed my rejection rate is low.

Can you measure the product to waste ratio? Do you know you have the right flow restrictor and it's installed correctly? Do you have any "complications" in your drain or product lines? (ie are they really long, kinked, connected to something that may introduce a restriction, etc.)?

There is a metre or so of extra flow in line that I have wound up. And a metre or so of extra line wound up on the waste line. I've put the small ball valve just before the t connection for the tds probe of the water going in line.

If I use the little ball valve to restrict the flow in it mess with the pump cutting it in and out.
