RO Filter questions
 

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

Crystal clear
 

That ro unit will be fine for your reef tank.

Thanks for all the input guys. Where would I go about finding a tds meter for that price? I would also like to make sure I have it hooked up correctly. It comes out very very slowly and it says its supposed to do 100gpd.

so I took the auto shutoff valve apart, only to find the seals inside are all mangled and have clearly been installed wrong. So now my next question is where would I get one of those ASO devices? This is turning out to be quite the headache.

simple drawing from Aquasafe Canada but shows connections, look up their site also as they have parts

If you're willing to manually turn on & off your RO system & monitor it while running, there's really no need for the ASO valve. I've actually never used mine since it's been finicky from the start & I've never been able to bring myself to fully trust it. The system would continue to produce waste water even after the shutoff valve on the pure water container closed. I've been thinking of bypassing or removing it altogether. I only make RODI water when I'm at home these days. Not everyone has that option, but it's pretty much the best way to ensure you don't end up with a flood at one point or another. Actually, I've even forgotten it's on when I'm at home & had the odd mini-flood. Generally I use the timer on the kitchen stove to remind me, but I've also installed a small battery operated water detector on the basement floor beside the collection tanks. This has saved me some major mopping up operations since there's no drain in my basement floor.
