For water shut-off use LeakSmart. I’m paranoid about water leaks and water damage when I’m away from home. I’ve always been in the habit of shutting off the main water supply to my house whenever we are gone for more than a day but I was looking for something more automated that I could do from anywhere. That is when I discovered the LeakSMART. You need to get a version that matches the size of your water supply. In my case I have 1 1/4 inch water supply and LeakSMART did not have a solution till recently. Once it came out I purchased it and scheduled a plumber to install. Well that happened a few weeks ago and so far this has perfectly met my expectations.
