Automatic Shut-Off Valve with Quick Connect Fittings

My system was constantly making RO water

Simple installation, just make sure you install the new exactly like you removed the old, TAKE A PHOTO FIRST. This item and the little elbow check valve are probably the two most important items you should have on hand.

Better phone support would be helpful

I have had no water filter for 7 weeks now. I have paid a plumber to come to my house 3x now. Each time, the issue is determined to be a different part. For the price of this part, I really wish someone had thought EARLY ON, it could be this, this or this causing your problem. Have me buy them and not pay and wait to get back in the plumbers schedule each time. Proactive troubleshooting. I can the. Return or keep the not needed items. But the way you troubleshoot is costing me. On the third time, for the $24, I feel you should have sent the item for free. Will this even solve the problem or will there be more parts you can suggest ???
