I have an aquamaxx 100gpd RO/DI unit, where can I get replacement cartridges and membrane? I'm not even sure what all I need to replace and when I look up the filters, I find tons, I have no idea what I need.
I bought my RO/DI from Global, and he was cool enough to change all of the filters that I needed changed. I'd call him and see if he carries the stuff for your brand, and if he does I'd take it to him!
When I took my unit up to him, he told me:
That needs replaced,
that doesn't
that does
etc.
The stuff he said to replace wasn't that much, and appeared in pretty ugly shape!
Also low water temp can affect it's output. You can get an adjustable flow control to compensate. Rule of thumb is 4:1 waste/water ratio. 100gpd RO membranes are ~90% affective where 75gpd and under are ~98% affective. I think Filmtec is rated at 50psi for that value. GE membranes might be different. Some old ones are rated for 60psi. All that can affect the output.
