  • If you buy a RO membrane housing you will need these. By Rob Coberg on 12/9/12

    If you go to home depo or lowes, the ones they carry look just like this "BUT" they don't fit on the side with the dual fitting on the housing. They are 1/8 too long and hit each other when you try to thread them in So you'll come back here to order the correct one's Plus this one has a check, that's for the processed water so it doesn't back up into the membrane.
  • Simple Fix By Chuck on 6/13/11

    Bought one of these to replace the one on the output side of my RO membrane that was failing. Simple to install and works great. If your auto shutoff on your RO filter suddenly stops working, and your waste water line starts constantly running this could be the problem. You can test the old one by removing it and blowing air through it with you mouth. It should not blow backwards (into the ro membrane) but should blow out of the membrane only. If it blows both directions replace it with one of these and you'll be back in business.
