Plumbing - Installing Water Shut off/Stop valve

I have metal water line without shut off valve under the sink.
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!

Use a sharkbite and there will be some for future use. Or fire up the torch thats on sale at Home Depot and sweat it off.

Thanks for your response, you mean cut it for this one time and install sharkbite shut off valve. In future sharkbite valve can be removed easily and need not cut pipe if needed.

A few ways.

Sweat out the elbow and solder in a valve (or elbow and straight valve)

Sweat out the elbow, clean as much as possible, then use compression fitting

Cut the pipe and use a compression fitting, or sweat in a solder valve


If cut too short, open wall, add new pipe.

just screw on a shutoff valve onto that threaded fitting and put your flexible hose on the other end. i recommend the ones with the handle you spin instead of the quarter turn ones those are harder for elderly people with arthritis or joint pain.
cant find a picture but it exists at lowes i know cus my sink had no shut off but the threading on the pipe, i simply shut off the water main, screwed it on, and screwed on the hose on the other end, and it is a proper shut off easy to turn for people with arthritis and hand pain like me

No, no, no.
Don't cut anything. Use a stop just like jonnyb listed.
Home Depot sells them as "Add a Stop", but I'm going to suggest you don't use that Waterline product (it's crap). Use the Dahl stop.

Second this. I used a Dahl "Add a Stop" as well last year to add a shutoff under our kitchen sink.
