RODI Unit producing A LOT of waste water, but only drops of filtered?

[Turnage]

Okay, thanks!! I have a manual flush valve, do I turn the flush valve on when my turn on/off valve for the supply is on?

Not sure since my rodi system doesn't have a flush valve. I would assume you want to keep the flush valve close when producing rodi water. You would only open it when you have replaced the carbon or membrane filter. Hopefully another r2r member can chime in on this.

Yeah, I know you typically flush after every RODI unit use. I’m just not sure how to flush it lol

I flush before use. Let’s see the valve

the flush valve bypasses the restrictor which should increase waste water. honestly i rarely use mine (cause i am lazy).

it allows you to flush the settled high TDS water out of the system instead of sending it to your DI resin.

to better explain, you will have water that creeps through your membrane between rodi runs,, that higher TDS water can either be flushed out before it hits your DI or you can allow it to go to your DI (if you dont use the flush valve

not sure you need a flush valve though if you are taking your unit off of the sink every time after use.. there would be no pressure to cause water to creep through the membrane

all it really does is save your DI resin from premature capacity

Red Sea reef salt

ok.. some (many) have lots of clay and stuff in them that can leave floaters or cloudy water.. i'd just make sure you let your salt mix, mix for 24 hours before using.

your system is only 4 stage, so i would really recommend a tds monitor to validate when the DI is expired. and change out your carbon timely, unless you test your waste water for chlorine regularly

Yes a TDS meter in my opinion is essential. Here's what I have. It's cheap but gets the job done.

City or well water?

You will hear noise as they start to fill. Watch your pressure guage and when it drops you will need at least a new sediment filter
