Works well at a good price

Includes o-ring caps and valves to get the job done. Video specifically for stuck valves. Like mine didn't just come off. Basically this means maintaining light pressure and continuing to unscrew the valve all the way, then back off turns slowly even if there is no thread in the pipe, the motion keeps the valve moving.

Pros
  • Easy to install
Cons
  • Reliable
