Why are My Drains Gurgling

Drain gurgling is a common problem, but if you don’t know what those gurgling noises are or what is causing them, it can definitely be a bit concerning.

So, what’s causing your drains to become so noisy?



Your Pipes Could Be Clogged

The reason your drains are making a gross gurgling sound, could be as simple as a clogged pipe. When your drains get clogged or blocked, the water flow is hindered, which means the air can’t get through either. The gurgling sound is actually the sound of trapped air bubbles trying to sneak past the obstruction in the pipe.

Sewer Line Problems

Under your home, there is a pipe that carries away all of the sewage and waste. This pipe leads right to the sewer system. But if there are issues in your sewer line, this could also cause that unsettling gurgling.

Tree Trouble

Tree roots can cause issues such as soft spots and sinkholes in your yard, when the trees are damaging your pipes. When the tree roots begin to grow through your pipe lines, it causes these issues to your property, and causes your drains to gurgle.

Your Pipes Could Be Clogged

Your Pipes Might be Broken

When your sewer lines break, air comes rushing in – which is what causes drains to get loud. However, that gurgling from your busted pipes can also come along with the repulsive stench of sewage. At this point, you will need to call out a professional, and fast. Busted sewer pipes can cause a lot of damage to your home.

Your Vent System or Pipes Are Obstructed

Vent system blockages trap air bubbles, and these air bubbles cause the gurgling in your drains. But why is this? This happens because every pipe in your home is connected to the vent system.The air is pushed out of vents out of the roof, but if they are blocked by leaves, sticks, tree nuts, or other things, the nearest escape for that air is your drains. This, sequentially, causes the gurgling sounds you hear.



A blocked pipe and a blocked sewer line both trap air bubbles that cause your drain gurgles. Be that as it may, a blocked sewer line can account for much bigger problems than a blocked freshwater line. One reason being, they are buried underground, which can make things formidable.

A blockage in your sewer lines can stem from things such as things from your cooking, like grease and fat. Other things that can cause clogs are rags, socks, feminine products and paper towels. Damaged pipes can also cause a blockage.

Your P-Traps Are Damaged

Damages in your P-traps are a common reason you could be hearing gurgling in your drains and, luckily, a fairly simple fix. The P-trap in the piece of curved pipe underneath your sinks. The function of this particular section of drain pipe is to trap all of the noxious gasses and odors from going back into your home.

Your P-Traps Are Damaged

When your P-trap gets damaged, or clogged, and water flow slows down, this causes a vacuum. This sequence then causes those concerning noises coming out of the drains. A sign that your P-traps are clogged or damaged is a strong putrid odor coming from the drains. Fortunately, this problem can easily be remedied by simply cleaning out or replacing your P-trap.
