An overflowing toilet is one of the most stressful plumbing emergencies a homeowner can face. Not only does it create a messy and unsanitary situation, but it can also cause water damage to your floors, walls, and cabinets. Understanding how to stop an overflowing toilet quickly can save you time, money, and a lot of frustration.
In this guide, Green Group will walk you through step-by-step instructions to handle an overflowing toilet, common causes of the problem, and how to prevent it from happening again. For homeowners in Nashville, Murfreesboro, and Franklin, we’re here to provide fast, professional plumbing services whenever you need them.
Step 1: Turn Off the Water Supply Immediately
The first and most important step is to stop the flow of water. Locate the shut-off valve behind the toilet near the base of the wall. Turn this valve clockwise to stop the water supply.
No Shut-Off Valve? Here’s What to Do
If your toilet does not have an accessible shut-off valve or the valve is stuck:
- Remove the Tank Lid: Quickly remove the lid of the toilet tank.
- Lift the Float Mechanism: Hold the float (a plastic or metal ball connected to a rod) up to prevent water from filling the tank.
- Close the Flapper Valve: If lifting the float doesn’t work, press down on the rubber flapper at the bottom of the tank. This will block water from entering the bowl.
Step 2: Use a Plunger to Clear the Blockage
Once the water has stopped, the next step is to remove the blockage causing the overflow. A plunger is the most effective tool for this job.
How to Properly Use a Plunger
- Ensure there is enough water in the bowl to cover the plunger head.
- Position the plunger over the drain hole, creating a tight seal.
- Use firm, controlled pushes and pulls for about 15–20 seconds.
- If water starts to drain, continue until the clog is cleared.
Choose the Right Plunger
For toilets, a flange plunger (which has an extended rubber piece) is the most effective type, as it forms a better seal around the toilet drain.
Step 3: Try a Plumbing Snake for Stubborn Clogs
If plunging doesn’t work, the next step is to use a plumbing snake (also called a drain auger). This tool can reach deep into the drain to break up or pull out the obstruction.
How to Use a Plumbing Snake
- Insert the snake into the toilet bowl’s drain and begin turning the handle.
- Push gently until you feel resistance (the clog).
- Rotate the snake to break up the blockage or pull it back out.
- Flush the toilet carefully to ensure the blockage is gone.
Step 4: Clean and Sanitize the Area
Once the overflow is resolved, it’s essential to clean and disinfect the area to prevent bacteria, mold, and unpleasant odors.
- Use a disinfectant cleaner on the toilet, floor, and any surfaces affected by the overflow.
- If towels or rugs got wet, wash them immediately in hot water.
- Allow the bathroom to air out, and consider using a fan to speed up drying.
Common Causes of an Overflowing Toilet
Understanding why your toilet overflowed can help you prevent it from happening again. The most common causes include:
1. Clogged Toilet Drain
This is the most obvious reason and can be caused by:
- Excessive toilet paper use
- Flushing non-flushable items (wipes, feminine products, paper towels)
- Build-up of waste and debris over time
2. Blocked Sewer Line
If all toilets in your home are experiencing overflow issues, the problem may be in the main sewer line, which can be blocked by tree roots, debris, or foreign objects.
3. Malfunctioning Fill Valve or Float
If the toilet tank overfills, it can cause continuous running and eventually lead to overflow. This is often due to:
- A stuck or improperly adjusted float
- A broken fill valve that doesn’t stop water flow
4. Sewer Line Backups
In severe cases, a clog in the city’s sewer line can cause wastewater to back up into your home’s plumbing system.
Preventing Future Toilet Overflows
Taking a few preventative steps can significantly reduce the chance of another overflow:
- Only Flush Toilet Paper and Waste: Never flush wipes, cotton swabs, feminine products, or paper towels.
- Limit Toilet Paper Use: Use moderate amounts of toilet paper and flush more frequently during use.
- Install a Water Pressure Regulator: If high water pressure is causing overflows, this device can help maintain safe pressure levels.
- Schedule Regular Plumbing Inspections: Green Group offers drain cleaning, sewer inspections, and routine maintenance to keep your plumbing system in top shape.
When to Call a Professional Plumber
While minor overflows can be handled with a plunger, there are times when it’s best to call a professional plumber:
- The toilet continues to overflow even after turning off the water.
- The clog cannot be cleared with a plunger or snake.
- You experience frequent or recurring toilet overflows.
- Sewage or foul odors are present, indicating a sewer line issue.
