If a toilet overflows, your first job is to cut off the incoming water. Reach behind the toilet, turn the small valve near the floor to the right, and do not press the handle again. Once the water stops rising, you can clean up safely and figure out whether you are dealing with a simple clog or something bigger.
Two Kinds of Overflow
Look at the bowl for a moment. If it is full and not going down, the drain is blocked. If water keeps trickling in even though nobody flushed, the tank is overfilling because its fill valve is stuck. The second kind will not stop until you turn off the valve or prop the float up inside the tank.
If the Valve Will Not Budge
Older shutoff valves can seize. Do not force one hard enough to snap it. Instead, take the lid off the tank, lift the float, and hold it up while someone finds the main water valve for the house.
Cleaning the Bathroom
Treat the water as contaminated. Put on gloves, pick up the water with old towels, and bag them for the wash or the trash. Mop with hot soapy water, then go over the floor and the base of the toilet with a disinfectant. If the bathroom is upstairs, peek at the ceiling below for a wet spot over the next day.
Clearing a Simple Clog
A plunger with a flange, the soft sleeve that sticks out of the cup, seals best in a toilet. Several firm pushes usually do it. Leave chemical cleaners on the shelf, since they rarely help and can splash back.
One more thing to watch: gurgling in the tub or water rising in another drain suggests the main line is involved, so stop using water around the house.
For repeat overflows, the drain can be cleared and the toilet inspected for damage. If several fixtures give you trouble, a whole-house drain evaluation can reveal a pattern. Call JPR Plumbing at (833) 603-1840.
