Sink Gurgles When Toilet Is Flushed

If your sink gurgles when the toilet is flushed, it is a sign that there is a problem with the plumbing in your home. The most common cause of this problem is a clogged vent pipe. The vent pipe allows air to enter the drain system, which helps to prevent the drains from siphoning and creating a vacuum. When the vent pipe is clogged, air cannot enter the drain system, and the drains will siphon, causing the water in the sink to gurgle.

There are a few other things that can cause a sink to gurgle when the toilet is flushed. These include:

A clogged drain
A broken or leaking pipe
A faulty wax ring
A problem with the septic tank

If you are experiencing this problem, it is important to have a plumber come and take a look at your plumbing system. They will be able to diagnose the problem and recommend the best course of action.

Here are some tips to help you prevent your sink from gurgling when the toilet is flushed:

Keep your drains clean by pouring a cup of baking soda down each drain once a month.
Avoid putting grease or food scraps down the drain.
If you have a garbage disposal, run cold water while using it to help flush the food scraps down the drain.
Check the vent pipe on your roof to make sure that it is not clogged.

By following these tips, you can help to keep your plumbing system running smoothly and prevent your sink from gurgling when the toilet is flushed.
