Top Reasons Why the Toilet Is Bubbling When the Shower Is Running in Georgetown, KY

Should you worry about a bubbling toilet? Possibly. A gurgling noise can indicate a problem deeper in your plumbing system, such as a nasty clog or blocked vent pipe. Here are the most common reasons why toilets bubble when you turn the shower on.

You Have a Plumbing Blockage

Have you flushed something down the toilet that you shouldn’t have? That foreign object can lead to a clog that creates negative air pressure. Because the water has nowhere to go, you’ll hear gurgling when you run the shower or sink.

Of all the things that can cause a toilet to gurgle, a plumbing clog is the easiest to fix. You can often resolve clogs with nothing more than a plunger. For more stubborn clogs, a solution of vinegar and baking soda or hot water and dish soap can loosen debris and make it easier to remove.

There’s a Sewer Line Obstruction

It’s not uncommon for clogs to form in central drain lines and municipal sewer lines. These lines can become blocked by foreign objects, excess waste, and even tree roots. If you’ve plunged your toilet and the clog won’t budge, suspect one of these lines as the culprit.

To determine the problem, ask your neighbors whether they’re also having issues with clogs. Municipal lines run on a shared drainage system, so several of your neighbors will also be affected. If your neighbors aren’t having plumbing issues, the problem is likely a blocked drain line. You’ll have to call a plumber for help.

A Clogged Vent Stack May Be To Blame

Your toilet is connected to a vent stack, which is a narrow pipe that goes through your roof. Its job is to regulate air pressure and release gas from the toilet. If the vent stack becomes clogged, it leads to the buildup of negative air pressure. In addition to a bubbling toilet, you’ll notice slow-moving drains throughout your entire house.

To fix a clogged vent stack, you’ll need a plumber’s snake and a helper. Climb on the roof and push the snake through the vent, then pull it back up to extract the blockage. If you don’t have a snake, use a hose to push water through the vent. Ask your helper to flush the toilet while you put your hand over the stack. If you feel suction, you’ve cleared the blockage.

Sediment Buildup Can Cause Toilets To Gurgle

Does your Georgetown home have hard water? Hard water causes mineral deposits from magnesium and calcium to build up in the toilet tank. Excessive sediment buildup can cause the toilet to bubble when you flush it. You might also notice the toilet bubbling when the shower is running.

To resolve the issue, you can use a staple pantry ingredient: white vinegar. Add a cup of vinegar to the tank, close the lid, and let it sit overnight. The vinegar will dissolve mineral deposits, giving you a squeaky-clean tank.

Another option is to install a water softener. These devices work by capturing mineral contaminants and keeping them from getting stuck in your plumbing fixtures.

Your Toilet Flapper May Need Replacement

Inside your toilet tank is a flapper, which is responsible for filling the tank back up when you flush. Flappers only last a few years before they become worn out and need replacement. If yours is old or damaged, your toilet might gurgle every time you flush it, not just when you turn on the shower.

It’s easy to replace a toilet flapper, but if you’re not comfortable doing so, call our plumbers in Georgetown, KY.
