Common Causes of Sink Pipe Leaks

Understanding why a leak occurs is the first step to repairing it successfully. The following are some of the most common causes of sink pipe leaks:

1. Loose Joints

A loose connection in your pipes can allow water to seep through and cause leaks. Joints may become less tight over time due to wear and tear.

2. Cracks in the Pipe

Cracked pipes are often the result of material corrosion or external damage. Cracks can be challenging to detect, but they are a frequent cause of pipe leaks.

3. Clogged Drainage System

A clog can build up pressure inside the pipe, leading to a leak through weak points. Regular cleaning of your sink pipes can help prevent clogs. For tips on maintaining your kitchen sink, see our article on cleaning kitchen sink pipes.

4. Deteriorated Seals

Over time, the seals or washers in your sink assemblies may degrade. This leads to leaks around the joint areas.

5. Incorrect Installation

If the pipes are not installed correctly, misalignment or loose fittings can result in leaks.
