- Mur-lok Elbow Check Valve 1/8" Male NPT x 1/4" Push Connect
Works but noisy By Tom on 5/20/2014Tom would recommend this product to a friendBought one of these to replace the one I got from Kent marine in my auto shut off kit.
I have to say that it does the job of restricting flow to one direction and I have not had any problems so far with its function. The problem that I do have with it is, that it is noisy. When in use and the water is flowing through the check valve the check valve make a high pitched vibration noise. My RODI is in my garage and I don't hear it unless I am out there so it is not a big deal. I am not sure why or if it is a sign that it will prematurely fail but I am going to get a backup just in case.

If you buy a RO membrane housing you will need these. By Rob Coberg on 12/9/2012Rob Coberg would recommend this product to a friendIf 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 6/13/2011Chuck would recommend this product to a friendBought 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.
