RO/DI just installed/what can I expect

[Ron Cote]

I have finally got my RO/DI system installed this evening. Please let me know if what I discribe is normal. I have an Ocean Reef +1 5 stage at 75 GPD.
Here is what I've observed thus far:
The pressure gauge reads 40 psi after the third stage
the TDS IN reads 14 - TDS OUT reads 0 at the DI unit.
It would appear that the current rate of about 1 gal of RO/DI to maybe about 4 gal of waste water.

Does this all sound normal for just installed and should I expect a better ratio of RO/DI to waste as time goes on.

Thanks

that sounds right. however your psi seems low, usually they run best at around 60psi.

[Ron Cote]

Are you truly saying that it should be 60 PSI after the third stage or prior to the 1st stage input?

Thanks

I'm running my 90 gpd w/40 psi. Seems to be working. TDS Reading from filter is "0". If you don't have a TDS meter. They can be had for about $30.00 from Marine Depot.

4-1; waste water to clean is normal

Really appreciate the input of your experience guys. I'm sure that you can all appreciate those early steps.
