Review on 🌊 RDEXP Automatic Water Level Control Valve for 1/2" Water Tanks - Water Float Valve by Jeff Rhodes

In the reverse image, the water level line is approximately 1/4" above this stainless steel screw, or 1/4" below when installed on a pool. I install it at my pool and it works fine. When turning on at full power, when turning off - no. End up buying 2 1/2" regular watering elbows (FF, FM) that can be adjusted in height by turning the elbow. I'm deducting 1 star because the documentation is in Chinese and the lock nut is not included. The lock nut secures the device is securely vertical and has a lock It's good that I still have one from my old valve.
