What should I do if my toilet is leaking?

If your toilet is leaking, it’s important to act quickly to prevent water damage. Check the tank and base for visible leaks. Turn off the water to the toilet at the supply valve, but do so with caution, as these valves can get brittle with age and if they break, you could have a major flood. If the leak only happens with the toilet is flushed, you likely have a drain or seal problem. If you’re not sure what’s causing it, or if it continues, calling a plumber is a good idea.
