Preventing and Fixing Balcony Drain Leaks That Impact Lower Floors

Balcony drainage pipes generally need to be installed with floor drains and drain pipes, which are typically made of PVC material. Over time, these pipes may develop leaks, and sometimes water can even leak down to the floor below. So, what should you do if the balcony drainage pipe leaks water down to the floor below? Let's learn about it together.

What to do if the balcony drainage pipe leaks water to the floor below

1. When your balcony drainage pipe leaks to the floor below, you should first identify the cause of the leak and the specific location of the leak. The method you use to repair it may vary depending on the reason and location of the leak.

2. To accurately determine the cause of the water leak from the drainage pipe, you will need to conduct a water test on your balcony. You can use a ball or a rubber stopper to seal the floor drain on your balcony, then pour water on the balcony floor to create a wet environment around the floor drain.

3. While conducting the water test, you should also carefully observe whether there is any leakage on the balcony below. If the lower balcony shows signs of leakage, it indicates that the water proofing work around your floor drain may not have been done properly, leading to the leak. In this case, you will need to break up the tiles on your balcony and redo the waterproofing. Once the waterproofing is dry, you can re-tile the balcony.

4. If there is no leakage observed on the lower balcony, you can connect a long flexible hose to the faucet and insert the hose directly into the drainage pipe. Open the faucet to let water flow directly into the drainage pipe, while closely observing whether the lower balcony develops any signs of leakage.

5. If the lower balcony shows leakage, it signifies that there is a breakage in your drainage pipe causing the leak. You will need to use appropriate methods to repair the leak based on the specific location of the leak in the drainage pipe, as solutions may differ by location.

6. If the leak occurs at the joint between the drainage pipe and the balcony floor, you will need to break up the tiles on the balcony, redo the waterproofing, and ensure that the floor drain above is tightly connected to the drainage pipe below. It is recommended to apply a leak-sealing compound around the joint and finally re-tile the balcony.

7. If the leak occurs at the lower joint of the drainage pipe, you can use PVC-u glue to repair the leak. Alternatively, you may use specialized repair tape for plumbing to tightly wrap the leaking area until the leak stops. If the leak persists, it would be advisable to consult a professional repair technician for help.

In summary：the above is a detailed introduction on what to do if the balcony drainage pipe leaks water down to the floor below. I hope this information helps everyone address the issue of balcony drainage pipe leaks. Be sure to choose the appropriate repair method based on the actual cause and location of the leak to prevent the situation from worsening.
