Hello, how are you?.. I turn to you as always looking for your great help ... On this occasion I have a dilemma with a cold water pipe ... They placed it for the passage of water but nowhere did they put a stopcock ... But it's already on the wall and everything ... The idea is to chop the wall a bit where I could go and place Jan stopcock for when the time comes for something to cut the water from there ... The key I have is the common thread but I have no idea how to place it having the pipes already fixed on the wall .... let's say the thread And if I cut the pipe as I do the thread on the wall? Or how do I make the union without thread while on the wall? I do not know if they understand me but I hope so greetings thank you very much!

Hi. You can discover, cut the pipe and make a thread from where the water comes and screw the pipe. Place the key and on the other side of it you can implement a double union to screw. You must discover at least 40 cm to work. Regards
