Common Causes of a Leaking Bathroom Sink Waste Pipe

Several factors can contribute to a leak in the waste pipe of a bathroom sink, such as:

Loose connections: Over time, the connections between the waste pipe and the sink or drain trap can loosen, causing water to leak.
Damaged pipe: The waste pipe can become damaged due to corrosion, rust, or physical impact, resulting in leaks.
Clogged drain: A clogged drain can lead to water backing up and leaking from the waste pipe.
Faulty pop-up drain: The pop-up drain mechanism can malfunction, causing water to spill onto the countertop and down the waste pipe.

Repairing a Leaking Bathroom Sink Waste Pipe

To repair a leaking bathroom sink waste pipe, follow these steps:

Identify the leak: Determine the source of the leak by visually inspecting the waste pipe connections.
Tighten loose connections: If the leak is due to loose connections, use a wrench or pliers to tighten them securely.
Replace damaged pipe: If the pipe is damaged, it will need to be replaced. Cut off the damaged section and install a new piece of pipe.
Clear clogged drain: Use a drain snake or chemical drain cleaner to clear any clogs that may be causing the leak.
Fix faulty pop-up drain: If the pop-up drain is the source of the leak, replace the drain assembly or cartridge.
