01Shutoff valves
A shutoff usually gets discovered exactly when it is needed most.
A shutoff left untouched for years often corrodes or mineralizes in place, and by the time it is needed it may not turn at all — a problem usually discovered during a leak rather than before one.
A shutoff that lets water past even when fully closed has worn internally and is no longer reliable enough to stop water in an emergency.
Older plumbing sometimes has no dedicated valve at a toilet, sink or washing machine, which means the whole property's main has to be closed for any work on that one fixture.
02How far to go
One seized valve found during other work is often a sign the rest are the same age.

03Why they seize
The same wear that makes a valve hard to turn is what keeps it from sealing.
A shutoff that is only ever left fully open collects mineral deposits and corrosion around its stem over years of sitting still, and the same buildup that keeps it from turning smoothly can also keep it from sealing completely once it does close. The problem is rarely visible from the outside; the valve looks the same as the day it was installed.
04If it won't close
If a fixture or main shutoff will not stop the water, the next valve upstream — another fixture shutoff, a whole-property main, or the meter's own valve — can usually be closed instead. Working backward toward the source keeps the water contained even when the closest valve has failed.
Knowing exactly which shutoff failed — main or fixture, and where — saves time once a plumber arrives, since replacing a seized valve is straightforward once the area is open, but locating the right one during an active leak is not.
05Questions
A shutoff that has seized in place is common in a valve untouched for years, and forcing it risks snapping the stem or cracking older fittings around it. A frozen valve is a routine replacement rather than a repair, and it is usually swapped for one that can be closed reliably again.
A valve that has not been operated in many years is a common find during other work, and replacing it while the area is already open is far simpler than doing it alone later, during an active leak, when the old valve is the one thing standing between the leak and the rest of the property.
The main shutoff controls water to the entire property and is usually near the meter or where the line enters the building. A fixture shutoff sits at one toilet, sink or appliance and closes only that connection, so work on one fixture doesn't require closing water to the whole property.
Water that cannot be stopped, sewage coming up, no water at all, or a smell of gas: urgent. A drip, a slow drain or a running toilet: worth fixing soon, but not tonight. When in doubt, shut off the water to the fixture and ask.
Where the problem is, when it started, what changed, whether the water is off, and the age of the fixture or heater involved. A photo of the problem and of any visible model label helps too.
