I'm working on replacing a kitchen sink faucet, home is 5 years old, and all of the valves are push/pull and plastic attached to 1/2" copper (I'm assuming that's the standard from online research). I replaced the faucet but now each time the motion sensor faucet shuts off while on cold, it kind of slams shut and the valve pops up, shutting the supply off. My plan is to remove the plastic push/pulls and replace them with 1/2" SharkBite x 3/8" OD (compression), metal 1/4 turn valves (link).
2 questions from this:
1) Is that a good idea? Replacing a valve that pops up when the water shuts off? Or could there be a bigger problem?
2) When I remove the push/pull plastic valve (by twisting it counter-clockwise until it comes off as I've read and seen on YouTube), do I need to cut back the copper pipe for the SharkBite to latch correctly? I'm worried about there being grooves or teeth marks from the previous plastic valve.
Thanks in advance
