5 Quick Fixes for an Overflowing Toilet

An overflowing toilet can turn a minor annoyance into a big mess and stress. Whether it’s from too much toilet paper, a drain clogged by something other than human waste, or a problem with the toilet’s water supply, you need to act fast before water spills onto your bathroom floor. Ignoring the clogged drain could lead to water damage or bigger plumbing problems down the line.

But there are some simple solutions you can try at home to stop the toilet overflowing, get it to flush properly and prevent it from happening again. From using a plunger to checking the toilet cistern, here are 5 quick fixes to get your bathroom back to normal.

Common Causes Behind Overflowing Toilets

Before we look at how to fix a flooded toilet, let’s look at why you might find your toilet overflowing in the first place. Here are the most common causes behind a blocked toilet:

• A toilet clog caused by too much paper or flushing other materials like wet wipes.
• A blocked system drain or soil stack vent that is preventing water from draining properly.
• Feminine hygiene products, paper towels or cotton balls flushed down the toilet.
• Tree roots growing into your main sewer line, blocking waste and water flow.
• A faulty toilet valve or float ball in the toilet’s tank can cause an overflow of water.

Whether you’re dealing with a sewer line blockage or have excess water filling the bowl, knowing what has caused the toilet to overflow is essential. It allows you to take the necessary steps to avoid a messy situation and keep your plumbing system in tip-top shape.

Solution 1: Turn Off the Toilet’s Water Supply

When your toilet is overflowing, the first thing to do is turn off the toilet’s water supply. This will stop more water from flooding the bowl.

You’ll usually find the shut-off valve on the wall, either behind or beneath the toilet cistern. Turn it clockwise to cut off the water flow and prevent water from spilling onto the bathroom floor. If you can’t find the valve, or it’s stuck, lift the cistern lid and manually push the float ball or tank float mechanism upwards. This will temporarily stop water from entering. Acting fast will keep the mess to a minimum and give you time to figure out what’s causing the problem.

Solution 2: Use a Plunger for Your Clogged Toilet

A toilet plunger can be the best friend you never knew you needed when you’re dealing with simple overflow-causing toilet clogs.

1. Make sure there’s enough water in the toilet bowl to cover the plunger’s rubber cup – this will create the suction.
2. Place the plunger over the toilet drain and make sure it’s sealed tight.
3. With steady pressure use a few pumps to push the clog down the drain.

Friendly tip: wear rubber gloves when you’re doing this. Also, be patient; like any blocked drain, it may take a couple of tries. Most clogs are caused by excess toilet paper use or other blockages so this usually works for those. Once you see water draining properly, give the toilet another flush to see if the clog is cleared.

Solution 3: Hot Water and Liquid Soap in the Toilet Bowl

Hot water and liquid soap can be a surprisingly effective way to fix an overflowing toilet, especially when caused by too much toilet paper or other soft materials.

Pour a small amount of liquid soap into the toilet bowl to lubricate the clogged material. Then carefully pour a bucket of hot water (not boiling, don’t want to crack the toilet bowl) from about waist height. The soap and heat from the water will soften the clog and make it easier for water to flow through. Let it sit for a few minutes then try flushing the toilet again.

This method is gentle and often works without needing to use a plunger.

Solution 4: Use a Plumbing Snake or Auger for Stubborn Clogs

For stubborn clogs that a plunger can’t clear, you may need to step it up with a plumbing snake or toilet auger. These long flexible devices are designed to reach deep into the toilet drain to break up tougher blockages further down the drain pipe.

To use it, feed the snake into the drain and turn the handle to push it through the clog. Once you feel resistance, turn the auger to break up or dislodge the clog. Slowly pull the snake out and see if any debris comes with it. Then try flushing the toilet to see if water drains freely.

This works for more stubborn clogs that won’t budge with a plunger.

Solution 5: Check the Float Mechanism in the Toilet Tank

If your toilet is overflowing, the issue might not be a blockage but a problem with the toilet tank’s float mechanism.

The float controls the water level in the toilet tank and determines when to stop filling. If you’ve got the float set too high, the tank will overfill and water will spill into the bowl. Here’s how to fix it:

• Take off the cistern lid.
• Check the position of the float ball or tank float mechanism.
• Adjust the float so that the water stops filling about an inch below the overflow pipe.
• You can usually do this by bending the float arm or adjusting a screw on the fill valve.

A properly functioning float mechanism will stop water from constantly flowing into the bowl and prevent overflows.

Why You May Need a Licensed Plumber

While there are many DIY solutions for an overflowing toilet, some problems require a licensed plumber.

If your toilet overflows frequently it may be a sign of a bigger issue like a blocked sewer line, tree roots in your pipes or a problem with your septic tank. Professional plumbers can diagnose and fix these complex plumbing issues so your home’s plumbing system runs smoothly.

Using a licensed plumber for necessary repairs saves time, minimises frustration, and prevents future damage to your bathroom and home.

How to Prevent an Overflowing Toilet

Preventing an overflowing toilet is often easier, less costly – and certainly less messy – than fixing an overflowing toilet. By adopting a few simple habits, you can avoid clogs and other plumbing issues that lead to toilet overflows. Here are some key tips to keep in mind:

• Only flush human waste and toilet paper; avoid flushing wet wipes, feminine hygiene products, or paper towel. And certainly any other foreign objects.
• Use less toilet paper, especially if you know your plumbing system is sensitive to blockages.
• Inspect the toilet’s float mechanism regularly to ensure the water level in the tank isn’t set too high.
• Schedule regular plumbing maintenance to check for tree roots or blocked sewer lines.
• Educate household members on proper toilet usage and flushing practices.

Following these steps can greatly reduce the chances of your toilet overflowing, saving you from future headaches.

Act Swiftly to Prevent Bigger Problems

When your toilet overflows, knowing why it’s happened goes a long way towards implementing the most appropriate fix. And fixing an overflowing toilet doesn’t have to be a hassle if you act fast.

Whether it’s a plunger, adjusting the tank’s float mechanism, or hot water and liquid soap, these simple solutions can save the day. But if your toilet overflows regularly or you suspect a bigger issue like a blocked sewer line or tree roots in your pipes it’s time to call a professional plumber.

Fixing the problem early prevents damage to your bathroom floor and plumbing system and saves you from more expensive repairs down the road. Act fast and your toilet will be good to go for the long haul!
