When I Plunge the Toilet, the Sink Gurgles: Understanding the Issue and Possible Solutions

Plumbing issues can be frustrating, especially when they occur unexpectedly. One common problem that homeowners often encounter is noticing gurgling sounds from the sink when they plunge the toilet. This phenomenon can be puzzling, but it has a logical explanation and several potential solutions.

When a toilet is flushed, it creates a sudden rush of water through the pipes. The gurgling sound in the sink is typically caused by air being displaced within the plumbing system due to the sudden change in pressure. This can happen for several reasons, including clogged vents, blockages in the sewer line, or improper pipe installation.

To help you understand this issue better, here are seven frequently asked questions and their corresponding answers:

1. Why does the sink gurgle when I plunge the toilet?
