The isolation valve. That small tap-like fitting on your water supply line that lets you shut off water to the sink without turning off your entire home supply.
Here's the thing: if you've never turned it, it's likely seized. And the moment you need it, during a leak, a burst pipe, or a fixture replacement, a seized isolation valve turns a minor problem into a major one very quickly.
What to do right now:
✅ Open the cupboard under your sink
✅ Find the isolation valve on the supply line
✅ Give it a gentle quarter turn, it should move freely
✅ Turn it back to the open position
If it won't move or if it moves but water keeps flowing, that valve needs replacing before it becomes an emergency.
Takes 30 seconds to check, as it could save you thousands.
