How to Diagnose and Fix a Toilet That Drains Slowly

Toilets are very common in daily life and are convenient to use, but they can encounter problems over time, such as slow drainage and lack of suction. Let’s take a look at some of the reasons behind these issues.

Top Reasons Your Toilet Lacks Suction and Drains Slowly：

1、Toilet Quality Issues

If the toilet has not been installed for long, it could be due to inherent quality issues or poor design, leading to slow drainage when flushing.

Solution：If you have purchased a toilet with quality issues or one that has a design flaw, you can contact the retailer for a resolution, including the possibility of a return or exchange. If a return isn't possible, it is advisable to remove the old toilet and replace it with a new, reputable brand that offers better quality.

2、Faulty Toilet Seal

When a toilet experiences slow drainage and poor suction, the most common cause is a faulty seal, which affects the toilet's sealing capacity. This results in air entering the toilet during flushing, which reduces suction.

Solution：Users can remove the damaged seal and purchase a new one based on the model of the old seal. Then, they can install the new seal in the toilet.

3、Toilet Misalignment

If the toilet is not properly secured and has shifted from its original position, it may block the drainage opening, which hampers flushing pressure and affects suction.

Solution：This situation is more complex and requires realigning the toilet to its original position. It is also necessary to use silicone sealant at the base to secure it, so it is recommended to hire a professional to handle the repair.

In summary：the reasons for slow drainage and lack of suction in toilets are outlined above. Although toilets are convenient, their internal structure can be complex, and troubleshooting issues can be challenging. It is advisable to seek professional repair services.
