I received the ball valve yesterday and easily installed it today. You cut 2" out of the pipe and slide the long end on one side of the pipe as far as it will go. You line up the other side with the pipe and using the disconnect clip, which is included, you slide it down and onto the other side 1" and that is it. No leaks and hardly any tools. 3boyslightingstore had the lowest price. I have used sharkbite products on other valves also and they are the easiest to use.
Haven't tried it you but it looks like the answer to my problem. Made out of brass and the instructions are easy to follow. Compact will fit into tight places.
