Shutting off the main water line does sound like a good way to prevent accidental usage, but it can actually cause its own set of issues. For example, if you have an older plumbing system, shutting off the main can sometimes stir up sediment or even cause seals to dry out, leading to leaks when you turn it back on. Plus, if you’ve got a sump pump or appliances that need water (like a humidifier), they might not work right while you’re gone.
I’ve seen some folks install smart water shutoff valves that can be controlled remotely or will automatically shut off if they detect a leak—those seem handy, especially for longer trips. But then there’s always the risk of tech glitches or power outages.
Curious if anyone’s actually had a problem crop up after shutting off their main? Or maybe there’s a workaround I haven’t thought of...
