Two comments about the video. First, valve replacement works if you have access to the exposed piping inside the house, e.g., in a basement. You can't access the interior piping on most houses as it is inside the wall unless you tear off the wallboard. Second is the advice given at the end about the washing machine hoses is very good. Almost 15 years ago, I had a rubber washing machine hose split. I happened to be home at the time, and while there was some damage, I shut the water off quickly. Had I not been home, it would have been an absolute catastrophe. I replaced the rubber hoses with hoses that have exterior stainless steel braiding reinforcement. That will prevent a hose rupture. I believe it is a good idea to replace washing machine hoses with new ones maybe every 5 years or so. Another observation - I don't remember ever seeing screws that can be driven into concrete before. Concrete nails, yes, but not screws.
