Walter is real good about getting back to people with questions. Try calling him also on Monday.
I would run the unit more to give the thing a chance to break in.. If you getting a 70 on the ro
end then you will be going through a lot of DI
resin. I hooked up a double DI
because I would burn through resin after a few hundred gallons. I now have the 8800 booster pump and I have not had to change my resin sense May. Still have a 1 on the TDS
, tested and have 0 on the PO4
and nitrates also. I have heard of membranes not running at 100% right out of the box, so maybe the membrane is bad... Give Walter a chance to get back too you.. Great customer service at AWI.
meters usually come calibrated so that should not be a issue, but stranger things have happened. AWI has calibration fluid..
