In that case, you have two options. First, try using a pair of pliers for extra grip—just be gentle, like you’re holding a baby bird.

If that fails, look for a main water shut-off for your entire house. It’s usually in the basement, garage, or near the water meter. Turning that off will kill water to everything, which is dramatic but effective. Then you can call a plumber and say, “I tried the toilet valve, but it had other plans.” You’ll sound like a pro.
