RO/DI operation questions

[adam2817]

OK, I just hooked up my NEW RO/DI unit from Coralife. Pure-flo II with the pump, to be exact. Is it normal for waste water to flow pretty freely and the PURIFIED water to trickle out? I got a 50Gpd filter. There isn't any operation information in the box other than set-up information. Any advice would be helpful.. Thanks :happy:

yes, the brinewaste water should be about 4 times more then the good water...get a measuring cup and let us know what you come up with.
What's the pump for, low water pressure?

The pump is for low water pressure, but it's supposed to save water. Instead of being 1-3 it's 1-2. 1 good gallon to 2 bad. I think the pump might be too much though. The waste water comes flying out and the good water drip drip drip. fast drip, but think it's more than it should be. My pressure might be just fine w/o the pump.

How much pressure do you have? I have 30 to 50 depending on my pump for the well. I have a 60 GPD unit that will give me about 11 GPD. I'm at a 5:1 ratio.
Water temp and pressure will effect the output alot.

I played with it a bit more and found a flow valve. They call it a flush valve, but if it's open, the water drips out, if it's closed, I get a 4-1 ratio, like I should. Thanks for the advice. :jumping:

I also read somewhere that the clean water will be low on Ph. Will I need to add buffer to the water B4 I put it in the tank? Or, will I need to add anything oter than salt, B4 putting it in the tank?

No, no buffer will be needed. Just add salt and a powerhead for 12-24 hours.
