Review on 🐠 Pawfly 2-3 Way Cross Aquarium Gang Valve - Air Flow Control Lever Valve Distributor Splitter with Check Valves, Suction Cups & Airline Connectors for Fish Tank by Marie Jensen

The O2 supplier we use for my wife's oxygen wanted $200 for a valve that could be switched back and forth between the CPAP injector and the daily cannula she uses. I carefully adjusted the outlet flow from the concentrator to 3. I checked the flow at the end of the 15ft hose, 3 to be exact. I installed this valve by splitting the flow to choose between two custom lines. Once installed, I selected them in order and measured the flow rate at the end of the hose. Exactly three on each device when a simple choice is made. I turned both on at the same time, measured exactly 1.5 on each device. I turned off both, the flow dropped to zero and the alarm went off. The valves seem to be holding up well. I tied it to the handle for my wife to use comfortably. It was the solution we needed and could afford. I know it's for the aquarium. So if you use it for other purposes, test and test again to make sure you get what you want. For us - PERFECT!
