Sewer Smell - Repair

Why is There a Sewer Smell in My House, and How Do I Get Rid of it?

Have you ever found yourself asking, “Why is there a sewer smell in my house?” – you’re not alone. This unpleasant and unwelcome odour is a common household issue, and it can be particularly vexing when the sewer smell originates from your bathroom. Let’s dive into the possible reasons for this smell and discuss some practical solutions.

The Source of the Smell

A whiff of a sewer-like smell in your home might set your nerves on edge, but before you panic, it’s important to understand where it’s coming from. The most common sources of this odour are:

  1. Dry P-Traps: Every drain in your house has a U-shaped pipe called a P-trap. It’s designed to hold a small amount of water that creates a seal, blocking sewer gases from rising into your home. If a drain isn’t used frequently, the water in the P-trap can evaporate, breaking the seal and allowing the sewer smell into your house.
  2. Blocked Vents: Your plumbing system has vent pipes that channel sewer gases out of your home. If these vents become blocked by leaves, bird nests, or other debris, the gases can get trapped and make their way back into your house.
  3. Cracked Sewer Pipes: This is a less common, but potentially more serious problem. If your sewer or drain pipes develop cracks, sewer gases can seep out and infiltrate your home.


The Sewer Smell in My Bathroom: Why it's There and How to Deal with it

If you’re noticing a persistent sewer smell in your bathroom, the culprit is likely one of the above problems. Check the water in your toilet bowl to ensure it’s not evaporating too quickly. You might also want to pour a bucket of water into your shower drain if it’s not frequently used.

Should the smell persist after these measures, it’s possible you’re dealing with a blocked vent or a cracked pipe. In this case, it’s advisable to consult with a professional plumber to inspect your system and rectify the issue.


Banishing the Sewer Smell from Your House: Effective Strategies

Once you’ve identified the source of the sewer smell in your house, there are several steps you can take to eliminate it:

  1. Maintain Your P-Traps: Regularly run water down infrequently used drains to keep P-traps filled. This simple step can help maintain the necessary water barrier against sewer gases.
  2. Inspect Your Plumbing Vents: If you’re comfortable doing so, you can check your vent pipes for obvious blockages. However, due to the potential hazards of roof work, it’s often best to hire a professional for this job.
  3. Repair or Replace Cracked Pipes: If a cracked sewer pipe is causing the problem, it will need to be repaired or replaced. This is a job for a professional plumber, as it often involves digging and heavy-duty work.
  4. Install Air Admittance Valves (AAVs): These devices allow air to enter your plumbing system when there’s a pressure drop, reducing the chance of a vacuum that could suck out P-trap water and let sewer gas escape. A professional plumber can advise you if this solution is right for your situation.
