Not only are the threads super sloppy with a ton of play, the check valve did NOT work at all. I tried both check valves and they both did the same thing, leaked! this is my 3rd time trying different check valves. I will never purchase another one on Amazon again. All Chinese garbage.

Takes a bit of force to open the valve so unless you have a large-ish pressure difference they will just stop the flow
