ok I have cut the restrictor tube twice, the first time the reading was 725 waste and 300 product and this 2.42 or a 2:1, the second cut I got a 700 waste to 300 good and this took it down to 2.33 or still a 2:1 ratio. but now the pressure is down to about 52psi? Or how much shorter can I cut this to? Here is how much I had cut both times and this is the length of the restrictor after the 2 cuts.

Any other options?

In my experience, shortening the FR can only make for more waste water, unless the end is crushed out-of-round. Be sure it's perfectly round. Look through the FR and be sure you see it perfectly round inside the tubing path. If not, manipulate it into roundness. If it is, cut half of the remaining white off. Worse that can happen, we'll send you another FR, but don't hesitate to make water in the meantime.

OK thank you.....I have placed a call just this past Friday afternoon and waiting on a call back. Could I add the low waste manual flush valve kit?

Ok I was able to call today and the gentleman that I had spoke to had said to take the restrictor out and put a ball valve in and then adjust that until I can get at least a 3:1 ratio. Once I see if we have a 1/4" ball valve or if I will need to make a trip to HD I will see what happens

I forgot to mention that the wast is 1050ml and good is 325ml. I think this is more than 90 gpd rate?

It's more, but within the +/-20% variance in manufacturer's spec.

Everything sounds good for you.

Hello. So I'm hoping you could help me out here. I have a 180gpd dual membrane RO/DI unit and was needing help with lowering the TDS going into the DI resin. I just purchased a new flow restrictor from SpectraPure (180gpd) and installed it into my unit. My TDS going into the first membrane is around 250ppm and the pressure going into the first membrane is around 76 psi with the use of a booster pump. Pressure going into the second membrane is 69 psi. The TDS coming into the DI cartridges is still reading at 20ppm. Both membranes are spectrapure standard 90gpd membranes and are both about a year old. I measured the product water and waste water just as described in your youtube video and got this: 480ml/min product and 1250ml/min waste. That comes out to a ratio of 2.6/1. I would really like to get my TDS <5 going into the DI resin. Would adjusting the flow restrictor help in doing that? Thank you in advance.

Luis,

Take a look at this video

http://www.youtube.com/watch?v=RRbdY...layer_embedded

This will help you out with the flow restrictor. There is not enough waste going through the membranes. This will cause higher membrane tds. We have better membranes that are far superior than our standard. The di will last 2-4 times longer.

First adjust your waste ratio to 4:1, and then tell me what the ro tds is.

JEremy

Thank you for the quick response. Once I get home I will adjust and then calculate again. Thank you.
