Reasons Your Drains Are Emitting Foul Smells

Your drains play a vital role in your plumbing system; they are responsible for removing wastewater. To ensure that your plumbing system works correctly, however, you must perform regular maintenance. Otherwise, you may start to experience issues with your drain, such as weird smells. If you notice a bad scent coming from your drain, it’s important to know the cause of the odor before you can hire someone to fix it. Here are a few of the most common reasons why your drain may be emitting a foul odor.

Dry P-Trap

One of the most common reasons why drains smell bad is because of a dried P-trap. The P-trap is the U-shaped pipe under the sink. It uses water to prevent sewer gases from entering the drain. If the P-trap dries out, however, it won’t perform its function and will cause your drain to smell bad. This often happens with sinks that haven’t been used in a while. Luckily, you can solve this issue by pouring water down the drain and rebuilding the water barrier in the P-trap.

Vent Pipe Clogs

Most plumbing systems also use a vent pipe to guide gases away from your home. These pipes usually lead up and out of the roof. Because of this, the vent pipe can get clogged with snow, leaves, debris, and animal nests. If it’s clogged, the gases can get backed up and cause your drains to emit a foul odor. Contact a plumber to inspect your vent pipe to determine if this is the cause of your issue.

Bacteria Breeding in the Water Heater

If the temperature of your water heater is set too low, it can transform into a breeding ground for bacteria. This can also occur when the water in the heater remains still for a long time, such as when you’re on vacation. The bacteria will come up through the faucets with your water and cause the drains to smell bad.

Not Using the Garbage Disposal Correctly

Some people treat their garbage disposals like a trash can. This, however, isn’t how garbage disposals are designed to work. Using your disposal incorrectly can clog and break it, which can cause the foul scent. You can avoid this by using your garbage disposal as it’s meant to be used. Don’t put anything in the disposal that doesn’t belong in there, including trash, harsh chemicals, large pieces of food, and bones. Additionally, you can deodorize the garbage disposal using baking soda, hot water, vinegar, and citrus peels.

Sewer Line Problems

If you notice the odor coming from every drain in your home—not just one of them—you may have a problem with the main sewer line. There could be a break in the main sewer line, or it may be otherwise damaged. Other signs of a sewer line problem include clogs and gurgling noises from the drains. If this is the problem, contact a plumber in Roswell, GA, as soon as you can. A break in the sewer line is a severe issue that may require a lot of plumbing work.
