Why is the plug hole noisy in your sink?

A noisy plug hole in your sink can be caused by air being trapped in the Plumbing, creating vibrations as water flows through. This can happen if there are blockages or if the pipes are improperly sized or installed. Additionally, if the water flow is too rapid, it can lead to gurgling sounds as it displaces air. Checking for clogs and ensuring proper venting can help reduce the noise.
