Why Does My Bathroom Smell Like Sewage? Exploring The Main Causes And Solutions.
A foul smell from your bathroom can be a source of embarrassment, discomfort, and concern, especially if it smells like raw sewerage. Most homeowners often associate such an odor with poor hygiene, but the truth is that the problem goes deeper than that. From blocked pipes to malfunctioning plumbing systems, various underlying issues could be causing the smell. In this blog, we help you explore the various causes of this problem and provide practical solutions to help you eliminate the foul smell for good.
Dry P-Trap
The U or P-shaped bend in your plumbing system's drain pipe underneath your sink or shower trap P-trap is designed to retain water, creating a seal that prevents sewer gas from coming back into your bathroom. However, if this trap dries up, the seal will break, allowing the raw sewerage smell to enter your bathroom. The solution is a simple DIY: pour water down your sink or shower drain to refill the trap. This is usually enough to fix the problem.
Blocked Vents
Your pipes need air vents to allow sewer gas to escape and keep the pressure balanced, preventing clogs or slow-draining pipes. These vents can become clogged with debris, causing the sewer gas to back up into your bathroom. You might need to climb onto your roof and look for blocked vents. You might need to hire a professional plumber if you're unable to remove the debris.
Leaking or Damaged Pipes
Cracked, broken, or damaged pipes can create openings that allow sewer gas to enter your bathroom. Sewer gas is contained within pipes, and any cracks or fractures provide an escape path where the gas can escape. However, it's essential to identify the problem earlier before it leads to water damage or mildew growth. You might need a professional plumber to diagnose the issue and provide a fix.
Blocked Drain
A blocked drain is another common cause of raw sewerage smells in your bathroom. Soap scum, hair, and other debris can accumulate over time, causing a clog. As a result, the wastewater will not drain correctly. The dirty water can create a backup that pushes sewer gases into your bathroom. The solution is simple – use a plunger, use a chemical drain cleaner or call in a professional plumber for a thorough drain cleaning.
Sewer Main Line Issue
Finally, if all the above solutions fail, the problem could be your sewer main line. A broken or blocked sewer main line can be challenging to diagnose and a much larger problem than the previous ones. If you've tried to address the problem using the above solutions and still have a foul odor in your bathroom, it could be time to call in the professionals. A professional plumber can use a video inspection to identify the problem and determine the best course of action.
Dealing with a bathroom that smells like raw sewage can be a frustrating experience. But, it's vital not to ignore the foul smell as it can indicate a more serious underlying problem. This guide covers the most common causes and solutions to the bathroom sewerage smell and provides practical tips on how to handle them. Remember, not all problems can be fixed by yourself. Some require professional attention. Therefore, it's best to call a professional plumber if you've tried everything else and still have an offensive odor in your bathroom.
