How To Fix Bathroom Sink Drain Leaks Underneath Gasket Threads

Bathroom sink drain leaks underneath the gasket are a common problem that can be easily fixed. The key is to identify the source of the leak and then apply the appropriate repair method.

There are a few different reasons why a bathroom sink drain might leak underneath the gasket. The most common cause is that the gasket has become worn or damaged. Over time, the gasket can deteriorate due to exposure to water and chemicals, which can cause it to crack or tear.

Another possible cause of a bathroom sink drain leak is that the drain flange is not properly tightened. The drain flange is the metal ring that holds the gasket in place. If the flange is not tightened securely, it can allow water to leak out from underneath the gasket.

Finally, a bathroom sink drain leak can also be caused by a cracked or damaged drain pipe. The drain pipe is the pipe that carries water from the sink to the drain. If the pipe is cracked or damaged, it can allow water to leak out from underneath the gasket.
