Why is My Sink Gurgling?

Possible Causes of Gurgling Sounds

Gurgling sounds in a plumbing system are usually caused by water flowing through the pipes and air bubbles trapped in the lines. A clog is forming, which will soon cause a blockage. The sound of bubbling water may also indicate that an obstruction has formed.

A Clog is Forming

A clog is a buildup of particles dislodged from their normal place in the line. These particles can be anything from hair to grease and any other debris that can accumulate in your plumbing system. When it comes time for these particles to move through the piping, they will become compressed and cause a blockage if nothing else moves them along first. As more particles accumulate and more pressure builds up behind them, you might hear gurgling sounds coming from under your sink or toilet tank lid when you flush them.

Air Trapped in Pipes

Air trapped in pipes can cause gurgling sounds. Air is often trapped in pipes when they are not properly sealed or when they aren't entirely filled with water. To get rid of the air, turn off the water supply to your sink and flush out the line by opening and closing the faucet.

Sewer Line Problems

An obstruction or blockage in your sewer line can result in gurgling sounds and sewage water backup into the house or basement. Sewer lines must be inspected regularly to ensure they stay clear of debris and other obstructions.

Backflow From Main Sewer Line

If you have a backflow preventer installed on your main sewer line, it might leak or malfunction. This can cause sewage to flow backward into the drains in your home, causing them to gurgle and overflow. The fix is to replace or repair the device, so it doesn't leak anymore.

Something is Blocking a Vent Pipe

Problems with vents and vent pipes in your home's plumbing system can cause water to flow back down into the drains and create gurgling sounds that may last for several minutes before stopping altogether. If this happens frequently, call a plumbing professional to inspect your house's vent pipes and ensure they're clear of obstructions.

Prevention

Start by ensuring that all valves are closed and opened properly to prevent gurgling under sinks. If you have a garbage disposal, ensure it is turned off when not in use. This will prevent food from getting caught in the pipes or disposed of.

Leak Detection of Atlanta

If you hear gurgling noises coming from underneath your sink, it may be time to call a professional plumbing service such as Leak Detection of Atlanta. The best way to determine if you leak is by using a plumbing snake to remove any clogs or debris causing the noise. If this doesn't solve the problem, you may leak somewhere in your plumbing system and should consider calling a professional to inspect it for leaks before they get worse.
