What kind of Pipe and how to approach?
I need to change out my cold and hot water shutoff valves due to them leaking (under the sink in kitchen). I want to put the newer 1/4” valves for replacement. I have done pretty much all my own DIY stuff. What kind of pipe am I looking at? Some sort of PVC or CPVC? They are cream colored. Due I cut them just below the metal valves or does part of that connection just unscrew? TIA. Picture included.
