It’s not exactly pleasant to catch a foul-smelling whiff of air whenever you pass by your toilet, sink, bathroom, or kitchen. That smell is likely sewer gas, and it can be tough to get rid of if you don’t know what you’re doing. Instead of trying to mask the smell with air fresheners and candles, here are seven ways you can get rid of it for good.
A sink overflow is a hole located either underneath or across from the faucet. It’s prone to the same accumulation of bacteria, soap scum, and hair that can clog and produce foul smells in a sink. Because it’s easily overlooked, the sink overflow usually doesn’t get cleaned as often as the sink itself. To clean your sink overflow, you can use a small bottle brush to clean out the hole and wipe away any buildup. Or, you can mix a solution of half chlorine bleach and half water to clear out any grime with ease.
When a toilet is installed, a wax ring is put in place underneath the toilet to seal the drain and prevent water seepage. If the wax seal is damaged, sewer gasses can seep through and produce bad odors. You can either replace the wax ring yourself or contact a plumber to do it for you.
If your toilet isn’t currently caulked to the floor, water may be leaking out and creating an unpleasant smell. Caulking a toilet to the floor prevents smells and keeps the toilet secure—a win-win for homeowners. The process is simple, and can be completed in a single afternoon.
If your drains are full of organic matter build-up or soap scum, you’ve inadvertently created the perfect environment for smelly bacteria to thrive. Fortunately, it’s easy to clean out existing bacteria and prevent new bacteria from growing in the same place.
The trusty non-toxic combo of baking soda and vinegar can clean drains naturally. Add one cup of baking soda to the clogged toilet or slow drain, then wait a few minutes. Follow with two cups of vinegar. Listen for bubbling and sizzling noises to indicate that the mixture is working. Wait another couple of minutes before either flushing the toilet or running water down the drain. If you still notice a smell, repeat the steps again.
Rather than using a liquid drain cleaner, which is more likely to hurt your drains than help them, we recommend that you use an enzyme-based cleaner. Instead of caustic chemicals, enzyme-based cleaners use good bacteria cultures and concentrated enzymes that naturally eat away at organic matter.
Your guest bathroom may not get much use, but it can be a major source of sewer gas odor because of its P-trap. The P-trap is a question-mark shaped piece of PVC or stainless steel located underneath your sink that traps debris and prevents clogs. Usually, the P-trap is full of water. But, in a rarely used sink, this water can evaporate, allowing sewer gasses to escape up the drain and into the air.
If you recently came home from a long vacation, or only live in your home seasonally, you may be greeted by a foul odor. That’s why it’s a good idea to get in the habit of running water down the drains of rarely used plumbing fixtures at least twice a month. This will ensure that the P-trap is full and keeps any bad smells at bay.
Leaky pipes can cause sewer gas smell, as they allow both water and sewer gases to escape from the pipe when they shouldn’t. Standing water on the floor or in the cabinet where your sink is installed is a sure sign of a leak. Another warning sign to look for is any dampness along the length of the pipe. You can run your hand along the pipe to check for this.
Since even the smallest leaks can turn into major plumbing disasters overnight, it’s best to fix them as soon as possible. You can buy some time with quick fixes, such as using duct tape or an old garden hose to cover the source of the leak. But, quick fixes are only temporary—the best way to ensure the leak is fixed properly is to work with a plumber.
The underside of your disposal’s splash guard, the black rubber piece you see when looking directly down your drain, is prone to accumulating stinky food waste. With a clean brush, turn the splash guard inside out and wipe away any old food residue, making sure to not reach your hands down the disposal. Once everything looks clean, turn on the disposal and run some hot water down the drain to rinse. You can add a little bit of dish soap to clean up any leftover food as well.
If these tips don’t help, you might be smelling actual sewer gases, also known as hydrogen sulfide. Drain pipes are designed to prevent hydrogen sulfide from entering the air in your home, but if the pipes are malfunctioning or compromised, the gases can flow uninterrupted. Along with a foul smell, prolonged exposure to sulfide can cause nausea, dizziness, and, in very extreme cases, death.
To keep yourself and your family safe, contact an emergency plumber if you suspect you may be breathing in hydrogen sulfide.
