Plumbing - Installing Water Shut off/Stop valve
I am looking to replace metal line with flexible one and install shutoff valve at the same time.
Lookin at youtube, it is advised to cut off pipe to remove existing valve.
My question is if we keep cutting pipe, no pipe length will be left to cut in future so how does it work if you need to replace it again in future?
Is any other option then cutting, doesn't existing valve open?
Thanks for help!
