RO/DI Q's & membranes

After reading numerous AZDesertRat posts about the subject, I have been scouring the net looking for adjustable flow restrictors. I came up with nada.

 

i posted pic of new membrane any idea who makes it so i can try and match a flow restrictor ? also in haste I actully plumbed it wrong now, now the discharge to good water ratio looks good if that means anything.

 

At the bottom of the page here are capillary tube flow restrictors which you trim according to your own water conditions for an exact ratio:

You will also find an adjustable needle valve type on that same page at the bottom. I tried the needle valve myself and had problems with it slowing over time causing the membrane to foul and die. I would stick with a capillary tube type and trim it myself for the perfect fit.

 

Thanks AZ...stupid Google.
