RO/DI - not sure what to think/do

[seuadr]

All,

 

I've got a mighty mite 50GPD RO/DI system. I purchased new stuff for it, but purchased the actual unit used.

 

I got the air,water ice "max" replacement pack - plus the RO membrane new. http://theh2oguru.com/filters/filter-packages/max-pack-replacement-filters-w-di.html

 

i rinsed the filters individually by running 5 gallons each of supply water through them, and then bypassed the RO membrane for 5 gallons and finally ran the entire system 5 gallons before using the water.

 

now i am seeing some weird readings (or mebby not weird?)

 

:edit: forgot to add - i am using a HM digital TDS 3 - brand new from intank

 

heres what i've got:

 

input tap water: 149 TDS

 

after first filter (5 micron sediment): 380 TDS

 

after the second filter (carbon): 420 TDS

 

after the RO: 65 TDS

 

after the DI: 360 TDS

 

so - i removed all the other filters and ran just the RO/DI figuring that the other filters were not rinsed properly, or crap or whatever and with just the RO/DI i'm seeing 105, with just the RO 35 (after flushing for a gallon)

 

i'm not sure what is going on here - I've got the system piped like this(with a couple extra filters):

 

it doesn't show a flow path for the RO - might i have it backwards and the output should be from the cap end? (doesn't seem like it..)

 

Thanks for your time,

 

Jared

well, i'm a monumental idiot. i never turned the waste valve back on after changing the filters. DOH
