How to Diagnose and Fix a Toilet That Leaks at the Base

Toilets can sometimes experience leaks at the base after prolonged use, leading to unpleasant odors in the bathroom. So, what are the reasons for water leakage at the bottom of the toilet? Let's take a look.

Reasons for Toilet Base Leakage

1、The flange ring at the bottom of the toilet may not be installed properly or may be aged or damaged, leading to a failure in sealing. In this case, a new flange ring should be installed.

2、The silicone sealant at the contact point between the toilet base and the floor may be damaged or cracked, resulting in leaks. In this case, the old silicone sealant should be removed and a new layer applied.

3、The toilet discharge outlet may not be aligned with the floor drain, causing waste water to leak from the gap. In this case, reinstallation is necessary.

How to Deal with Toilet Leakage

1、Upon discovering a leak, we need to determine the root cause of the problem. Once the underlying issue is identified, addressing the leak becomes easier. While many people may call a professional plumber, there are times when a plumber may take several days to arrive. Therefore, it’s important to try to identify the problem and attempt a DIY fix to prevent the situation from worsening.

2、If the toilet base is leaking, it's usually due to issues with the sealing silicone or the flange ring. In this case, the old silicone sealant at the bottom of the toilet should be thoroughly cleaned off, and a new flange ring should be installed. If the leak originates from the toilet tank, a detailed inspection of the internal components should be conducted, replacing any damaged parts with new ones.

3、If there is a backflow issue, it’s essential to check if the drainage pipe is clogged. If so, it’s necessary to hire a professional to help clear the blockage. If there is water seeping from the surface of the toilet, a check should be made to see if the toilet itself is cracked. If it is, it will be necessary to replace the toilet.

summary：The above is a detailed introduction to the causes of water leakage at the bottom of the toilet and how to address the issue. I hope it helps everyone. There are many reasons for toilet base leakage, and different causes require different solutions, so it’s essential to first identify the root cause.
