## Description

1/4" RO Water Tube Fitting Check Valve,Straight Quick Push to Connect Check Valve,for Ro Water Systems,Water Filter,Water Purifier

Review: Value for the money - The check valve works as intended. I added this valve to the existing system. Installed easily and quickly. I looked on YouTube as to why the water was continuously flowing so I changed this with a new membrane and a flow valve and a drain valve and now using water as it should. YouTube has some great troubleshooting videos to help see why the system doesn’t work as intended. Not sure I need so many valves but now have extras.
Review: They work well. - No leaks. I'm happy with them.
