A leaking toilet base can be stressful, unpleasant, and destructive in equal measure. It’s a common problem that can be caused by a number of different issues within your entire sewage system. Some are minor fixes, and others can require more extensive (and expensive) repairs.
At TWC, we have put together a checklist of potential causes of toilet base leakage for you to work through, in order to narrow down the problem. Read on for our tips on diagnosing and resolving issues if your toilet is leaking from the base.
Why is Your Toilet Leaking From the Base?
A toilet leaking at the base suggests that there is a problem either with the seal (which should be watertight) or the plumbing. Whether it is an issue with the installation of your toilet, like loose closet bolts, or a broken part like a worn-out wax ring, the TWC team are here to help you identify and resolve the problem.
Worn-Out Wax Ring
The wax ring is a key component of your toilet. This part forms a watertight seal between the toilet and the drainpipe, ensuring that gas and sewage cannot leak into your bathroom. Wax rings will experience wear and tear over time, or may be installed incorrectly, which leads to leaks. To find out whether your wax ring is the cause of your leaking toilet base, try dropping some food colouring into the toilet tank. If the water on the floor becomes the same colour, changing the wax ring should fix the problem.
Loose Flange Bolts or Floor Flange
Otherwise known as a closet flange, a toilet flange is a pipe fitting that securely connects the toilet to the bathroom floor and the drainpipe. Depending on the material that your flange is made of (PVC, aluminium, copper and brass are all common), it may corrode or could have been installed too loosely. When your toilet base is leaking, you should check that the flange is fitted properly, the closet bolts are tight enough, and that there is no damage to the flange itself.
Loose Connection Bolts
Connection bolts connect your toilet to the flange. If your leaking base is accompanied by wobbling or movement when you sit on the toilet, you may need to tighten your connection bolts. If they are too loose, they could be the cause of water accumulating around the toilet.
Cracked Toilet Base
Toilet bowls can crack due to accidental damage, over-tightening of bolts, or wear and tear. If the damage is deeper than a cosmetic, even a hairline crack may allow water to leak out. Some cracks can be repaired with porcelain epoxy, but many will require the replacement of your toilet base.
Incorrect Installation
Many of the problems in this list can be a result of the improper installation of your toilet. This could mean that the toilet is placed unevenly, or the wax ring has not been fitted properly to create a waterproof seal. If you suspect that your toilet has not been fitted properly, asking a trained professional to check it over is the quickest and easiest way to find and resolve the issue. At TWC, our team of highly experienced engineers are always happy to help.
Clogged Drain Line
If there is a clog in your drain line, water could be backing up in your plumbing and leaking from the base of the toilet. A blocked drain line will eventually impact the whole property, so it is relatively easy to identify. If multiple fixtures are clogged, the toilet is gurgling, or the toilet or bathtub are filling up when the sink taps are turned on, you are likely to have a clogged drain line. This will require the help of a professional to rectify, so call TWC! We can use CCTV drain cameras and specialist equipment to locate and clear the blockage without causing further damage to your pipes.
Leaking Water Supply Line
Did you know that the water supply line within the boundaries of your property is your responsibility? If the supply pipe is leaking, there are often visual signs, including water collecting around the base of your toilet. Other indicators include waterlogged areas outside the home, particularly during dry weather, and a water bill that is higher than expected. Much like a clogged drain line, if this is the cause of your leaking toilet, you will require a professional to examine and repair your plumbing.
What to do when your Toilet is Leaking from the Base
There are a number of DIY fixes you can try to fix the leaking from your toilet base. The exact fix will depend on what the cause of the problem is. If you don’t know what is causing your toilet to leak from the base, then trying the below could cause more harm than good. If you feel like you need professional help, please don’t hesitate to contact our team for expert guidance.
Tightening the Toilet Bolts
Locate the toilet bolts (they will be situated around the base of the toilet and are sometimes covered by small plastic caps that you can gently remove with a screwdriver). Tighten each side alternately and be sure to work in small increments — please remember that over-tightening the bolts can cause the toilet to crack, so be careful. You should check that the toilet bowl can no longer shift against the floor after each tightening to make sure that you only turn the bolts as much as necessary.
Replacing the Wax Ring
This DIY fix requires removing the entire toilet, but can be a relatively cheap and simple option to fix the leaking base. Turn the water off at the shut-off valve and flush the toilet to drain the water, and then loosen the toilet bolts and detach the water supply line hose. Remove the toilet and scrape the old wax seal off the flange. Centre the new wax ring, carefully position the toilet, and reattach everything. You can check that the wax ring is installed correctly by placing toilet paper around the base of the toilet and then flushing.
Inspecting for Cracks
A visual inspection of your toilet will allow you to identify any cracks. Even a hairline crack can be an indication of a leak, so be sure to check around the base and bowl carefully, using a torch if necessary.
Correcting Installation Errors
Using the tips and instructions in this blog, you will be able to check the parts of your toilet that may have been installed incorrectly. If the error is not something that you feel comfortable correcting yourself, you can then call a drain care professional like TWC to proceed for you.
Addressing a Clogged Drain Line
You should be able to identify a clogged drain line yourself but fixing it may require a professional as the issue could be deep underground. If the sinks and bathtubs are taking a long time to drain, the toilet is gurgling as well as leaking, and water is backing up, you are likely to have a blockage further down in your pipes. A plunger or a drain snake may be able to help, but if not, the TWC team will be happy to assist you.
DIY vs Professional Solutions
It can be tempting to attempt a DIY fix to save money when a problem arises in your property, but with amenities like plumbing, getting it right is absolutely vital. If you are not a drain care professional, and you make a mistake or improperly fit a replacement part, the problem can become much worse and much more expensive to fix.
Frequently Asked Questions
How Long Does It Take to Fix a Leaking Toilet Base?
On average, most DIY repairs for a leaking toilet base can be completed within a few hours, while more complex fixes may take up to a day. The exact time will depend on the cause of the leak. For minor issues, such as tightening loose bolts or replacing a worn wax ring, the repair time could be as little as 1-2 hours. However, if the problem involves more significant damage, like a cracked toilet base or an improperly installed flange, the toilet repair could take longer. More significant problems may not have a suitable DIY solution, and likely need the help of a professional draincare expert or plumber.
Is the toilet leaking from the bottom an emergency?
Whilst not every leaking toilet is an emergency, it should certainly be considered urgent. Regardless of the apparent severity of the leak, you should aim to get it fixed as soon as possible. There may be more leakage that is not immediately visible, and water damage can be widespread and difficult to repair.
What’s the Difference Between a Leaking Toilet Base and a Leaking Water Supply Line?
A leaking toilet base usually indicates a problem with the wax ring, flange, or improper installation, where water leaks out from the base of the toilet. In contrast, a leaking water supply line occurs when the pipe that brings water to the toilet has a loose connection, crack, or other failure, leading to water pooling near the base but not necessarily coming from it. To differentiate between the two, check the source of the water. If it’s coming from behind the toilet, it’s likely the supply line; if it’s coming from under the toilet, the toilet base is the culprit.
Can a Leaking Toilet Base Increase My Water Bill?
Yes, a leaking toilet can cause a noticeable spike in your water bill. Even small leaks around the base can lead to wasted water, especially if the problem is related to a failing wax ring or a toilet leak that goes unnoticed for some time. In severe cases, you may also be dealing with leaks in other parts of the plumbing system.
If your water bill is higher than expected, and you notice water accumulating around the toilet, it’s crucial to address the issue promptly to avoid further water usage and cost increases. If your bill is higher because of a leak, you may be eligible to claim a water bill allowance to help towards the cost.
What is the average cost to fix a toilet leaking from the base?
We understand that cost can be a worrying aspect of a drain care disaster, but this is highly dependent on what has caused the leak. A new wax ring, if you were to fit it yourself, can be purchased for around £10. However, to completely replace your toilet (dependent on the model and the needs of your property), you could be spending up to £500.
At TWC, we are committed to full transparency. Our engineers will discuss the problem with you and ensure that you understand all of your options. We’ll make sure you know exactly what the issue requires so that you can make an informed decision.
What Are the Signs of a Bad Wax Ring on a Toilet?
A bad wax ring on your toilet can lead to several noticeable issues. The primary sign is water leaking from the base of the toilet, which can manifest as puddles on the bathroom floor after flushing. Other symptoms include unpleasant sewage odours, indicating that the toilet seal is not working properly, and wobbly or shifting movement of the toilet.
If the wax ring has deteriorated, it can no longer create a watertight seal, which allows both water and foul gases to escape. Replacing the wax ring should solve the problem if this is the cause of your leak.
Can a Loose Toilet Cause Leaks at the Base?
Yes, a loose toilet can be a common cause of leaks at the base. When the flange bolts that secure the toilet to the floor become loose, it can lead to a base leak. You may also notice the toilet wobbling or moving when in use, which further loosens the seal and exacerbates the leak.
Over time, this can cause water to seep out from underneath the toilet and accumulate on the floor. Tightening the flange bolts or replacing the flange if it’s damaged can usually fix this issue and prevent further leaks.
Is It Safe to Use My Toilet If It’s Leaking from the Base?
It is generally not safe to continue using a toilet that’s leaking from the base. Even minor leaks can cause toilet safety concerns, as water can damage your bathroom floor, create slip hazards, and lead to mould or mildew growth. Additionally, sewage gases can escape from a faulty seal, posing health risks. If your toilet is leaking, we would recommend to stop using it until the issue is fixed.
How Can I Prevent Future Leaks from My Toilet Base?
To prevent toilet leaks from occurring in the future, regular maintenance is key. This includes periodically checking and tightening flange bolts, inspecting the wax ring for signs of wear, and ensuring that your toilet is properly installed. Avoid over-tightening bolts, as this can crack the toilet base. If you suspect issues with the plumbing or drainage system, our team can help identify the issue and unblock or repair your drains. Proper care and timely repairs will go a long way in preventing toilet base leaks and maintaining a leak-free bathroom.
Summary
A leaking toilet base can lead to a variety of issues, from unpleasant odours to significant water damage if left unaddressed. Understanding the potential causes, such as a worn wax ring, loose bolts, or incorrect installation, will help in diagnosing the problem more effectively.
While some repairs may be manageable as DIY tasks, others, like clogged drain lines or severe installation faults, require professional assistance. If you are unable to fix the issue yourself or prefer expert advice, seeking the help of trained engineers like those at TWC will ensure the problem is resolved quickly and efficiently.
