Review on 🦈 SharkBite Compression Angle Stop Valve, 1/2 x 3/8 - Push-to-Connect, PEX, Copper, CPVC, PE-RT (4 Pack) by Chris Fisher

I used two of these to replace leaking poor quality shut off valves on two toilets. Highly recommended. If you're using PEX, watch a video on how to remove the ferrule and old valve without cutting the PEX (using pliers, a small flathead screwdriver, and then a heat gun to easily remove the valve). This helped a lot as there aren't many pipes sticking out of the wall. I didn't have to re-cut the PEX as it was just cut.
