DIY Plant Watering Application
I'm building my own IOT plant watering system, and these valves are an effective way to prevent back-flow into my mini centrifugal water pumps. The forward pressure required to push water through them in the normal direction is quite low, and they are causing minimal reduction in pressure on the delivery side of the valve. I would use them again.

Good for special use with oxygen concentrator
I have 2 oxygen concentrators for night use, one in the next bed room one in the garage. I have tubing from both so if we have guests staying, I can run the one in the garage because of the noise. I used 2 of these small check valves in line will each concentrator, so I can just turn on the one in use, without changing the tubing around.
