Nothing — just your hand
Step-by-Step
1
Find the shutoff valve
On the wall behind the toilet, where the supply line meets the wall. It's usually a small oval or lever handle.
2
Turn it clockwise
Turn the handle clockwise until it stops. For a lever handle, turn it 90° so it's perpendicular to the pipe.
3
Flush to confirm
Flush the toilet. The tank should not refill. If it refills, the valve may not be fully closed or may be worn.
4
For repairs, drain the tank
With the valve closed, flush the toilet. The tank will empty and not refill. Now you can work on the flapper, fill valve, or other tank parts.
WHEN TO STOP
- If the valve won't turn, don't force it — it can break and spray water.
- If the valve is corroded or has mineral buildup, it may need replacement.
- If the valve doesn't fully stop the water, it's worn and needs replacement.
WHEN TO CALL A PROFESSIONAL
- The shutoff valve is stuck, corroded, or won't fully close.
- The valve is leaking from the stem when you operate it.
- You want to replace an old gate-style valve with a modern quarter-turn valve.
