RO Filter questions

[Slyguy00]

So I just got an ro filter system, and have my plumber friend hooking it up. But he seems to think its hooked up incorectly and the instructions included are beyond garbage. How do I know if everything is hooked up right, and im actually getting RO water coming out. Is there a way to test or prove the water is ro? The shutoff valve that has 4 hoses connected to it, doesnt seem to make sense. Any information I can find online doesnt seem to help. Its a crystal clear 100gpd ro filter system. And info would be a huge help. Thanks

How many filters do you have, ie how many stages
I can't find any info on y0ur system

Here is a good link, page 8, that shows the connections to the auto shut off valve

To check out put water you need a TDS meter (total dissolved solids)
Make sure you throughput at least 5 gallons before you use the water, to get rid of impurities in the filters

I have 2 filters and the membrane. I have been informed it isnt for fish tanks. Its by crystal clear. Any thoughts? Also thanks for the advice

Get a TDS machine 25-35$ and it will tell you. The TDS should be zero coming from RO/DI not sure for straight RO also it will tell you when you need to change your filters

That ro unit will be fine for your reef tank.
