A sewer blockage can have a devastating effect on the home’s plumbing. It can lead to foul odours, plumbing issues, and even health hazards if left untreated. Detecting sewer blockages early is crucial to prevent extensive damage and costly repairs. In this blog, we will discuss the signs, common causes, and solutions for detecting and dealing with sewer blockages.


Signs of Sewer Blockage:


Slow Drainage:


One of the most common early signs of a sewer blockage is slow drainage throughout your home. If multiple drains, including sinks, tubs, and toilets, are draining slowly, it could indicate a problem in your sewer line.


Unusual Gurgling Noises:


Listen for unusual gurgling or bubbling noises coming from your drains or toilet when the water is running. These sounds can be a clear indication of air trying to escape through a blocked sewer line: blocked plumbing services.


Foul Odours:


Sewer blockages can lead to unpleasant odours in and around your home. If you notice persistent sewer-like smells, especially in your basement or near floor drains, it’s a sign of trouble. In this situation, you can optimised plumbing services to fix the problem as soon as possible.


Backed-Up Toilets and Drains:


Frequent toilet backups or water backing up into sinks or bathtubs can be a severe indication of a sewer blockage. This should be addressed promptly.



Sewage Backup:


The most obvious sign of a sewer blockage is sewage backing up into your home. If you notice sewage in your basement or on your property, it’s a clear emergency. At this time, when you suspect your sewer is blocked, contact expert plumbing services immediately.


Common Causes of Sewer Blockages:


Tree Roots Penetration:


Tree roots are a common cause of sewer blockages. They can infiltrate your sewer line, seeking moisture and nutrients. Over time, these roots can create clogs and cracks in the pipes.


Accumulated Debris:


Grease, hair, soap scum, and foreign objects can accumulate in your sewer line, leading to blockages. Avoid pouring grease down the drain and use drain screens to catch debris.


Pipe Degradation:


Over time, sewer pipes can deteriorate, corrode, or collapse. This can result in blockages and requires professional repair or replacement.


Flushing Inappropriate Items:


Flushing non-flushable items like baby wipes, paper towels, and feminine hygiene products can lead to blockages in your sewer line.


Bellied Pipes:


A sagging or bellied section of your sewer line can collect waste and cause a blockage. This often happens due to soil settling or shifting.


Solutions for Detecting and Dealing with Sewer Blockages:


Professional Inspection:


If you suspect a sewer blockage, you should optimise expert plumbing services. It’s best to contact a licensed plumber for a professional inspection. They can use specialised tools like sewer cameras to diagnose the issue accurately.


Drain Cleaning:


Minor blockages caused by debris buildup can often be cleared with drain cleaning methods such as snaking or hydro-jetting.
