What Causes Water Won't Shut Off
When a faucet, toilet, or other fixture won't stop running and the handle or valve won't shut it off, the internal valve mechanism has failed. This can be a cartridge failure, a broken shut-off valve, a stuck gate valve, or a corroded ball valve. If the fixture shut-off doesn't work, you need to use the main valve.
Boise-specific factor: Many older Boise homes have original gate valves (the round-handle type) that corrode and seize over time. When these fail, there's no way to shut off water to individual fixtures without closing the main valve. Newer homes typically have quarter-turn ball valves that are more reliable.
Signs You Have Water Won't Shut Off
Watch for these warning signs in your home:
- ✓ Faucet or toilet won't stop running when turned off
- ✓ Handle spins freely without stopping the water
- ✓ Under-sink shut-off valve is stuck and won't turn
- ✓ Water continuously flows from an outdoor faucet
Can You Fix This Yourself?
Try the fixture's individual shut-off valve (under the sink, behind the toilet, or in the wall). If it's stuck, do not force it — old gate valves can break and flood. Turn off the main water supply instead and call for service.
If the problem persists or you're unsure, call a licensed plumber. Attempting complex repairs without proper tools can cause further damage and void warranties.

Frequently Asked Questions
Why won't my faucet shut off?
The internal cartridge or valve has failed. Use the under-sink shut-off valve to stop water flow. If that valve is also stuck, shut off the main water supply and call for repair.
Should I replace my gate valves with ball valves?
Yes. Gate valves are prone to seizing after years of non-use. Quarter-turn ball valves are more reliable and easier to operate in emergencies. Replacement costs $75-$150 per valve.
