hello Traders,maybe you can help me though this. ran my ro today for the first time. on sap. set pressure at300 with recirculating needle valve open . permeate meter was running at 3.5 and concentrate meter at .5. almost right at original owners marks on flow meters. permeate was a little higher. sap sugar was 1.3% going in 5% coming out concentrate side, .7% coming out permeate side? is this normal? it's a waterloo- small 300gph antique. I shut the ro down when I realized it. maybe 100 gallons of sap. it does have a lot of leaks, one's pretty big at 300 psi. feel like i'm missing something. any pointers would be much appreciated.
