RODI Output

[Gusto]

Hi Everyone,
I have a 5 stage RODI and I had an extra membrane housing and decided to add a second membrane and I was really going through DI resin.. I then decided to take off the second membrane and go back to the way it was and I was still going through DI Resin so I decided to test the output and the DI water coming out of the output is more than the waster line.. I know it should be at least 3 or 4 to one.. What could cause so much output? Thanks

Could the flow restrictor be missing?

Is there one in the tubing? I do have one like the below just the 800 model.. does that have a restrictor in it? Makes sense because I was moving around the hoses when I added the second membrane

Mine looks different but that‘s probably one.

Changing the flow restrictor on your membrane

Flow restrictors are essential to a properly functioning RO system. Be sure to have the appropriate flow restrictor for the membrane you have. If you decide to change your membrane to a higher or lower GPD membrane, you must also replace the flow restrictor to correspond with the membrane.

Thanks... I will have to call them tomorrow and see. Just not sure why I'm getting so much output..

Yes, this is it. Make sure to flip it up when making water. Flip down to flush the membrane on occasion like after making a large batch of RODI water. Also, ensure in/out alight with the restrictor like in that picture.
