  I am running two 75 gpd membranes in parallel. Which restrictor valve should I purchase? The one for 75 gpd or the one for 150 gpd?

  Bulk Reef Supply Hey Aaron,
  If you are running two membranes in parallel you would want a 75gpd flow restrictor for each of them.
  
  If you are running two 75gpd membranes in series (series would be like our 150gpd water saving upgrade kit), then you would have a single 75gpd flow restrictor attached to the second membrane in the series.

  which flow restrictor do i use for the dow filmtec 75 GPD membrane? the 550 or the 800?

  Bulk Reef Supply Hey Michael,
  You would want to order Sku 2000021 " 75GPD Flow Restrictor". Which does happen to be the 550.

  I have a Kent Hi-s r/o system,35 gpd. I recently purchased the 75 gpd membrane from you with a restrictor. My question, where does the restrictor go? I do not have one on my system to replace. Please help. Thank you

  Bulk Reef Supply Hey Brian,
  The flow restrictor always goes on the waste water line. Every unit has one (otherwise it would operate very poorly if at all) but they aren't always the same type. Sometimes they are located inside of the waste water line itself. I would take the waste water tube out of the elbow where it connects to the membrane housing. Pretty good chance you will find it hiding in the tubing there! Then you can remove it, insert the tubing itself back into the fitting, and then cut the tubing to install the inline flow restrictor from us!

  I purchased the 75 GPD upgrade kit for my 5-Stage Plus, do I need to upgrade my flow restrictor from the current 550 to the 150 GPD one?

  Bulk Reef Supply Hey Pete,
  If you have the 150gpd upgrade kit, it will add a second 75gpd membrane but you would keep the existing 75gpd flow restrictor.
