Rodi Help

[qhduong]

Ok I was dumb and connected the waste line to input, and input as the waste line. The rodi still produced some water out of the output. Is this water usable or should I dump it?

If I understand you right….. DUMP.

So the water went though the system backwards??

 

[qhduong]

Yeah I think it went backwards. I have about 5 gallons of this "bad water" mixed in my ato reservoir of 14 gallons that already went into the system. And another 10 gallon or so in storage. How bad is this?

Yeah I guess it did... No wonder my water was so slow lol.

Any damage to membranes or filters you think?

I’m still not following. What chamber did the source water go into first?

 

[dakoop]

If in doubt get rid of it and start fresh. Flush the system if you have the option

Water went through flush valve first, lol

Connect properly and flush
Check output with tds meter

 

[qhduong]

For what it's worth the water connected wrongly still produced 0 tds the whole time.

There's a good chance the water it produced never touched carbon, so probably still has chlorine in it. This can be mitigated by adding a dechlorinator (like Prime) to the ATO reservoir. It's also likely that it did not go through the membrane. It may have touched some DI resin so may have been slightly "filtered". But I would not risk it.
As far as your RODI system, set it back up properly, run it for 5 minutes without collecting any water, and then collect some and test for chlorine, tds, etc.

What I'm concerned with more now is its been 24 hours and I've been topping off the tank with this water.

1) what's the harm to the tank?
2) even with 0 tds, is the water that harmful? Input typically is 25 tds to start.

Answer to #2: Probably not. It's more likely to provide "food" for undesirable microorganisms or algae, but aside from chlorine and chloramines, not catastrophic, especially if it's just a small amount over a short period of time.

Edit to add: if it's been over 24 hours, chlorine is no longer an issue, just possibly ammonia if your water company used chloramine.

Yeah no chloramine here. I'll just dump the water in storage and do some water change and call it good lol. Just felt so stupid after I found out.

Running water backwards through an RO membrane will damage the membrane.
Suggestion: hook the system up correctly, and then run it for 10 minutes and report here the TDS of your
1) tap water,
2) RO water, and
3) DI water
