How to Install an Automatic Shutoff and Check Valve on a Reverse Osmosis System

Great video!! Struggled for three days before finding it. Thank you so much for posting.

In a 5 stg unit do you still run the low pressure line in from membrane and out to di stgs or at the very end of the unit closets to float valve.

I wonder why this needs the check valve while the Auto-shutoff valve already prevent the water flow back to that direction? Is the check valve purpose to conserve water?

[@teddygas9689]

What’s the check valve for? I have purchased an auto shutoff and a float valve only

[@flrpower5628]

You don't need the check valve if you install an auto shutoff valve.

So you replaced 2 check valves? Or is the valve on the bottom called something different?

[@charlesbonkley]

Seemingly, the bottom, waste-line fitting was removed for no apparent reason but was reinstalled.

I don't get it man, why are all these people installing the check valve on the waste water line? It seemed wrong and I see your video shows check valve installation on the purified water line, which makes way more sense since it's often going into a pressurized tank that could potentially backflow water into the membrane...

Per "Pure Water Products", Its purpose is to prevent backflow into the unit in the event of a clogged drain. You can add a check valve to the drain line of any RO unit.

I wished to know the proper way for my GE system and downloaded the PDF for it. Sure enough, the check valve was labeled to go to the waste line leading to the faucet. The other line leading to the manifold only had a screen filter in it. I'm learning this because I changed my spun pre-filter, carbon post filter & RO membrane last week and am getting white flecks all through my water now. The tank fills and shuts off within minutes, so It doesn't seem to be a check valve issue. Really stumped why so much calcium is getting through this past week.
