HELP with RO/DI system

[Andy23109]

HELP!!!! Hi all setting up an ro/DI system and having some trouble. the flow is well down even though I'm running a booster pump. Pressure is good at 85psi. running 1 sediment 2 carbon 2 75gpd ro membrane and 2 di canisters. I will be the first to admit its a cowboy setup but would appreciate any insight. I'm only getting 220ml of ro/di to 610ml of waste water

What size flow restrictor do you have?

We have a valve on at the minute but we have a 550ml restrictor from brs on order but we have messed about a it and now making 310ml of ro/di at 0.00tds to 450ml of waste but the waste water is coming out dirty now
