You might not be able to see it, but there’s a lot happening in the sewers connected to your home. As bacteria breaks down waste, a collection of gases form, and one in particular—hydrogen sulfide—can be significantly odorous. While residential plumbing is designed to keep these odors out, sewer gas may occasionally creep into your home. If you detect this rotten egg-like smell, American Rooter—a Connecticut drain service company—says it’s essential to address the stench.

In some cases, breathing in this gas can be bad for your health, eventually causing dizziness, nausea, or even death. However, since gas is invisible, it can be hard to figure out where it’s coming from. As experts in odor detection and resolution, American Rooter highlights some common sources of sewer gas, as well as how they can be remedied.

5 Sources of Sewer Gas a Drain Service Can Fix

1. Dry or Damaged Trap

The curvy pipes found under drains are designed to hold a small amount of water to block gases. If you use these drains so sparingly that the water evaporates, gas will seep through. Similarly, dry traps can cause a drain’s internal seal to rot or crack. Occasionally running water down seldom-used sinks and bathtubs may help prevent this problem, but if the seal is damaged, you’ll need professional drain repair.

2. Clogged Drain

A clogged drain can cause bacteria to flourish. Using approved products may prevent soap scum and other debris from accumulating, but in more severe cases, it’s best to call a professional drain cleaning service.

3. Sewer Backup

A bad odor is a clear warning sign of a sewer backup. If it’s caught too late, a backup can be disastrously messy. If you notice water backing up or draining slow in your sinks or tubs, call a sewer cleaning specialist to resolve the issue.

4. Faulty Toilet Seal

Under the base of your toilet is a wax ring that creates an airtight seal between the toilet and its drain. If a toilet becomes loose, this wax seal may lose its ability to keep air out, allowing gas to seep in. The only way to fix this is to remove the toilet from its base and replace the wax ring.

5. Loose Pipes

Small openings in pipes may not be big enough for water to leak through, but gas is another story. Although these air leaks are not visible to the naked eye, a drain service can use specialized equipment to spot the leak and tighten the pipe.
