I'm running a measly 5 stage. 10 micron, 5 micron, carbon, ro, mixed di. So far so good. The sediment filters get pretty gunked up though.

Some additional info, I have a whole house sediment filter and water softener. TDS into the RO/DI is 400-500 and out of the membrane is 10-20.6 - I just added the cation and anion cartridges to see if the resins last longer. I'm on well water and suspect CO2 is using up the anion in the mixed bed.

Apologies in advance for any thread derailment but....What kind of membranes do you run on your system?
Spectrapure 5 stage here as well.Spectrapure MaxCap 90 w/manual flush - 5 stages
source water - 75tds
pressure from the tap - 85psi
- 0.5 micron sediment filter
- 0.5 micron carbon block
- 90 gpd Spectra Select 99% membrane
- 2 capillary flow restrictors
one trimmed for summer water temps
one trimmed for winter water temps
to produce a 4 to 1 waste to product water ratio
- MaxCap high capacity DI cartridge
- SilicaBuster high capacity DI cartridge
I use this same system except I have the max cap 180. And I use the booster pump to reach 85 psi.Spectrapure MaxCap 90 w/manual flush - 5 stages
