How to Safely Clean Toilet Overflows?

A toilet overflow causes wastewater to be spewed all over the bathroom floor. Not only is the situation a hygiene disaster, but the excess water can damage the floor structures. Safely cleaning up a toilet overflow and preventing long-term structural damage requires the following steps.

What are the common causes of a toilet overflow?

Clogs are the biggest cause of toilet overflows. Toilets are designed to flush waste and toilet paper—and not a range of miscellaneous items. Flushing diapers, paper towels, sanitary products, solid goods, or even flushable wipes can lead to major blockages in the toilet bowl.

Although a toilet is manufactured to flush toilet paper, attempting to flush an excessive amount can clog the bowl. Too much toilet paper caught in the toilet bends can clog the s-shaped trap, which is designed to prevent foul-smelling sewer gases from coming up the drain and into the bathroom.

The sewer line connects the home with the city sewers. A blockage in the sewer line caused by non-flushable items, such as those previously mentioned, can lead to a gradual buildup in the line and an eventual toilet overflow, gurgling drain, backed-up sink, or overflowing washing machine.

Clean and disinfect

High-efficiency toilets, specifically those manufactured before 1997, are prone to toilet overflows. These low-flow toilets are made to conserve water. While seemingly a cost-saving benefit, the water conservation feature actually prevents waste matter and toilet paper from flushing down easily.

A toilet may overflow with clean water instead of wastewater. When this is the case, the problem may lie within the tank. Check for a broken tank float or a stuck handle. Once the issue is found, turn off the water at the water shutoff valve and make repairs.

How toxic is wastewater?

Wastewater overflows from the toilet are highly contaminated. In fact, wastewater is classified as black water—the most toxic of all three categories of floodwater. Although wastewater is 99.9 percent water, the other 0.1 percent of the toilet overflow should be a concern to homeowners.

The remaining 0.1 percent of wastewater contains nutrients, like phosphorous and nitrogen. Toilet overflows also include dangerous waterborne bacterial pathogens, such as pathogen strains of E. coli, Salmonella, Shigella, Vibrio, and Campylobacter. The bacterial content in wastewater should prompt homeowners to proceed cautiously with cleanup.

How to Safely Clean Toilet Overflows

How do homeowners safely clean the toilet overflow?

1. Turn off the water supply

First, turn off the water at the water shutoff valve. When the valve is not located on the supply line, stop the flow of water by lifting the toilet tank lid and pulling up the float. If both solutions fail, shut off the water at the main water supply line.

2. Unclog the toilet with an auger

A toilet auger is the most effective tool to snag the clog and yank it out. This tool is ideal for unclogging toilets due to its ability to navigate the s-shaped trap inside the drain pipes. Alternately, the auger can break up the clog and allow water to flow through.

3. Remove standing water

Moisture has the ability to whisk upward and into drywall quickly. Consequently, when cleanup of the wastewater from a toilet overflow is delayed, the water will soak into cabinets and walls and lead to significant water damage and mold growth. Bacteria can also readily spread.

A wet/dry vacuum should be utilized to suction up as much standing wastewater from the bathroom floor as possible. Use thick towels or blankets to absorb any remaining moisture. Take care to thoroughly launder the towels and blankets after cleaning the overflow.

4. Dry the bathroom

A wet bathroom invites pests and mold colonies. The dampness can also cause damage to the floor structures. After a toilet overflow, rapidly dry the area using rented high-volume fans. Typically, one fan will do the job; however, multiple fans may be needed if the overflow spreads to other rooms.

5. Clean and disinfect

Fully disinfecting the bathroom after a toilet overflow is critical to health safety. Start by cleaning the entire bathroom—even areas not directly affected by the overflow—with soap and water. Prepare a disinfecting solution by mixing one cup bleach with one gallon of water.

Dipping a clean rag into the disinfecting solution, wipe down all the surfaces inside the bathroom. The bleach in the disinfectant kills any bacteria and mold spores. Additionally, the solution will neutralize offensive odors. The bleach simultaneously disinfects the bucket and rag used during the process.

Cleanup of the toilet overflow should be done promptly to prevent further damage, especially to rooms nearby or below. The wastewater can ruin not only the baseboards and flooring, but the subfloors, drywall, ceilings on lower levels, cabinets, carpeting, and trim.
