Step 1:

Open and put aside the toilet tank cover.

Step 2:

Reach in and push down the rubber flapper valve to seal the water from getting into the toilet bowl.

Step 3: 

Lift the float level that controls the waterline of the tank.

Water still overflowing?

Shut off the control valve located at the back and bottom of the toilet.

Did the overflow stop? Great! Here’s what to look for now…

• Look for other overflowing issues in the house and stop using all other toilets and sinks
• Need to replace a part yourself? Here are some you can find at Home Depot or on Amazon.
• If only one toilet is clogged, use a plunger to free the clog. Check out this helpful video by Home Depot for more help below.
