Adafruit water solenoid review (v2)

Demonstration of this Adafruit water solenoid from Amazon: This water solenoid: https://smile.amazon.com/gp/product/B...

As one reviewer put it: «Description says it is 1/2" NPS, but other reviews said 1/2" NPT would work. My experience with this valve is that 1/2" NPT does not work and there are no readily available connectors for 1/2" NPS. I tried connectors that just said 1/2" pipe threading, and those did not work (I'm assuming those were NPT).» [https://smile.amazon.com/gp/customer-...]

A more standard pipe thread size is NPT, a.k.a. FIP/MIP (female/male iron pipe) [https://terrylove.com/forums/index.ph...]

Despite that, I seem to have gotten it to work.
