However, it is important to address the issue as soon as possible to minimize potential water damage. An Overflowing Toilet is a Nightmare for Homeowners Picture this: You flush the toilet, and it gets clogged up. The next thing you know, the water level begins to rise and fill the toilet bowl entirely. In most cases, it stops before it reaches the top and spills over onto the bathroom floor, but what do you do when the water pours out of it onto the floor? How can you limit the potential risks to you and your family? When your toilet overflows, it can leave you feeling helpless, that’s why there are some easy steps you can take to ensure you keep more water damage from occurring. The Most Common Causes of an Overflowing Toilet Clogged toilet: A clogged toilet is often caused by flushing too much toilet paper or other non-flushable items down the toilet (paper towels, sanitary pads). A clog in the toilet can cause the water in the bowl to rise and potentially overflow. Faulty flapper valve: The flapper valve is a rubber seal that covers the opening at the bottom of the toilet tank. If the flapper valve is not functioning properly, it can cause water to flow continuously into the toilet bowl, leading to an overflow. Broken fill tube: The fill tube is a small plastic tube that connects the toilet tank to the toilet bowl. If the fill tube is broken or disconnected, it can cause water to flow constantly into the toilet bowl, leading to an overflow. Sewage backup: An overflowing toilet may be caused by a sewage backup in the main sewer line. This can be caused by various factors, such as tree roots growing into the sewer line or a blockage. Sewage backups can be serious and may require the assistance of a professional plumber. Other issues: Other potential causes of a toilet overflow include a faulty float valve or a malfunctioning toilet handle. In these cases, the problem may need to be repaired by a professional plumber. How to Stop an Overflowing Toilet and What to Do Next We have the answer if you’re pacing, trying to figure out, “How can I stop my toilet from flooding my house?” Step 1: Turn off the Water Supply Turn off the water supply to the toilet by turning the shut-off valve behind the toilet clockwise. This will stop water flow into the toilet bowl and help prevent further overflow. Step 2: Remove Excess Water Remove any excess water from the floor using a towel or mop. Be sure to use caution when handling any water that may have come into contact with sewage, as it can contain harmful bacteria. Step 3: Figure out what caused the overflow Determine the cause of the overflow. Several potential causes of a toilet overflow include a clogged toilet, a faulty flapper valve, or a broken fill tube. If the cause of the overflow is a clogged toilet, try using a plunger to remove the blockage. If the plunger does not work, you may need to use a toilet auger or drain snake to clear the blockage. If the cause of the overflow is a faulty flapper valve or a broken fill tube, you will need to replace these parts. These repairs may require some basic plumbing skills, so you may need to call a plumber if you are uncomfortable tackling them yourself. Step 4: Test the Repaired Toilet Once you have repaired the cause of the overflow and removed the excess water, flush the toilet to ensure it is functioning properly. If it flushes correctly, you can turn the water valve back on (counterclockwise) to allow it to fill up with water again. What to do if a Sewage Backup Causes the Flooding If a sewage backup caused the overflow, you should call a professional plumber or water remediation team to assess the issue and make any necessary repairs. Sewage backups can be dangerous and should be handled by a trained professional. However, if you have to deal with something you believe to be caused by sewage backups, make sure to wear strong rubber gloves, What Are the Potential Risks After a Toilet Overflow?
