If a toilet overflows, close the shutoff valve behind it right away. If the valve will not turn, take off the tank lid and lift the float to stop more water from flowing in. Do not flush again, and clean up the water with gloves before trying to clear the clog.
Stop More Water From Coming In
The shutoff valve is usually on the wall or floor behind the toilet. Turn it clockwise until it stops. If it is stuck, lifting the float arm or the float cup inside the tank stops the fill valve. You can also push the flapper closed so tank water does not drain into the bowl.
Clean Up Safely
Overflow water may contain waste. Put on rubber gloves and use old towels to soak it up. Wash the floor with soap and water, then disinfect it. If water got under the toilet, along baseboards, or into a ceiling below, it may take more time to dry.
Try to Clear the Clog
Use a flange plunger, which has a rubber extension that fits into the toilet drain. Press down slowly to create a seal, then plunge firmly several times. If that does not work after a few tries, stop. Too much force can break the wax seal under the toilet and cause a leak.
Check the Rest of the Home
Run water in a nearby sink and watch the toilet and tub. If water rises in another fixture, or you hear gurgling, the clog may be in the main line. Stop using water and call for help.
Avoid chemical drain cleaners in toilets. They rarely work on these clogs and can splash.
If the toilet keeps overflowing, the line can be opened and the toilet checked. If clogs are becoming a habit, a look at all the toilets and drains in the house can help. Call JPR Plumbing at (833) 603-1840.
