Sewer backups, a plumbing nightmare, occur when wastewater can’t flow away from your property, causing it to reverse course and back up into your home or business.

What causes sewer backup? Factors like tree root intrusion, grease build-up, ageing sewer lines, and heavy rainfall overload the system. Sewer backup prevention strategies like proper waste disposal, regular maintenance, and backwater valve installation can protect your property from this messy predicament.

Raw sewage harbours harmful bacteria and viruses, while the moisture promotes mould growth, compromising indoor air quality. Recognising early signs like slow drains, gurgling sounds, or unpleasant odours is crucial to prevent further damage.

The consequences? Extensive property damage, health hazards, and even environmental pollution. Imagine sewage inundating your space, leaving a foul odour and substantial mess. Let’s learn more about sewer backups so you can be prepared!

Common Causes of Sewer Backups


Clogged Drains and Pipe Blockages

So, what’s causing these blockages? Often, the answer lies in what we send down our drains. Flushing inappropriate items like nappies, wipes, or even dental floss can lead to blockages. Pouring grease or oil down the sink might seem harmless, but over time, these substances can solidify and build up, narrowing the pipe and impeding water flow.

Debris, like food scraps, hair, and soap scum, can also accumulate and cause blockages. Even small items can cause significant problems if they lodge in a pipe and start collecting other debris.

Use drain covers to catch debris, and dispose of grease and oil in the bin rather than the sink. Regularly cleaning your drains with environmentally friendly products can also help keep them clear.

A little bit of prevention can save you from a whole lot of trouble down the line!

Invasive Tree Roots

Imagine a battle raging beneath your feet, where tree roots infiltrate your sewer lines in their relentless quest for water.

Roots can grow and worm into pipes, causing blockages and damaging the pipe structure. Several factors contribute to this subterranean showdown.

The proximity of trees to sewer lines is a major one. Also, cast iron pipes and other older pipes are more susceptible due to their weaker materials and potential cracks.

Proper tree maintenance, such as pruning and watering, can also keep roots satisfied and make them less likely to seek sewer lines. Installing root barriers can also deter roots from reaching pipes.

Ageing or Damaged Sewer Lines

Time waits for no one, and unfortunately, that includes your sewer lines. Sewer lines can show wear and tear over time, leading to potential backups. Damaged sewer pipes due to ground shifting or improper installation can increase the risk of backups.

Now, picture this highway riddled with potholes and cracks. These disruptions can obstruct the smooth flow of wastewater, leading to backups.

Regular inspections are crucial in identifying potential issues early, preventing sewer line backups before they escalate into full-blown backups.

Think of it as a routine check-up for your sewer lines, helping to ensure they’re in good health. After all, a stitch in time saves nine, or in this case, can save your property from a messy sewer backup!

Heavy Rainfall and Flooding

As water levels rise, excess water can infiltrate sewer lines, causing them to become overloaded and resulting in backups. But don’t worry—there are ways to prepare for and mitigate the effects of heavy rainfall and flooding on sewer systems.

Signs You May Have a Sewer Backup


Slow-Draining Sinks and Tubs

This problem often arises from a blockage in the main sewer line, preventing water from draining away as it should.

But how can you tell if it’s a sewer backup or just a localised clog? If multiple drains in your home are slow or blocked, it’s likely a sewer issue. So, don’t just shrug it off the next time your sink is slow to drain.

Gurgling Sounds from Plumbing Fixtures

Have you ever heard your sink, toilet, or tub singing a gurgling tune? These sounds are caused by air bubbles trapped in the pipes due to a blockage or backup in the sewer line.

Unpleasant Odours

A foul smell or odour from your drains often signals a sewer backup, a scenario where sewage reverses course, bringing a host of unpleasant smells. Remember, this isn’t just a nuisance; it’s a warning of potential plumbing issues.

Preventing Sewer Backups: Best Practices

Preventing a sewer backup requires a proactive approach and regular maintenance. Regular plumbing inspections can identify potential issues before they escalate into backups.

Start by properly disposing of waste and avoiding flushing items like grease, paper towels, and feminine hygiene products. Installing a backwater valve can also prevent sewage from flowing back into your home during a sewer backup.

What to Do During a Sewer Backup Emergency


Safety Precautions

Safety should be your number one priority when dealing with a sewer backup. Exposure to raw sewage can pose significant health risks, including bacterial and viral infections. Therefore, donning protective gear such as rubber gloves, boots, and eye protection is a must.

It’s not just about cleaning up the mess but also about preventing further contamination. Sealing these materials in sturdy, leak-proof bags before disposal is crucial.

When it comes to a sewer backup, clearing the blockage and protecting your health and property is important. So, suit up, take precautions, and tackle the situation head-on.

Stopping the Backup

When a sewer backup occurs, swift action is vital to mitigate damage. Start by turning off all water sources in your home, such as taps and appliances, to lessen the water flow into the sewer system. This can help ease the backup.

Try using a plunger or a sewer snake to dislodge any blockages in the pipes. Be gentle and patient; clearing the obstruction may take several attempts.

If these efforts don’t resolve the problem, it’s time to call in a professional plumber. Persistent backups might indicate a serious issue like a damaged sewer line, which requires expert attention and specialised tools to fix properly.

Acting quickly minimises property damage and prevents further complications, saving you significant hassle and expense in the future.

Cleaning and Disinfecting

First, it’s essential to understand the importance of thorough cleaning and disinfecting. Sewer backups can leave behind harmful bacteria and viruses, and the moisture can promote mould growth. It’s not just about making your property look spick and span again. It’s about ensuring your home is safe and healthy.

Start by removing any solid waste and debris. Next, clean all affected areas using a detergent solution, including floors, walls, and surfaces.

After cleaning, it’s time to disinfect. Use a household disinfectant or a bleach solution, and follow the manufacturer’s instructions. This will give your property a protective shield against harmful germs. Dry and ventilate the area thoroughly. This step is crucial to prevent mould growth. It’s like airing out your gym shoes, only on a larger scale after a workout.

When to Call a Professional Plumber


Ever found yourself knee-deep in a DIY plumbing project, only to realise you’re in over your head? You’re not alone. While tackling a sewer backup yourself is tempting, sometimes it’s wiser to call a professional plumber.

Imagine facing a stubborn blockage that no amount of plunging can fix or noticing recurring backups that suggest a deeper issue. They use advanced equipment like drain cameras to spot issues like invasive tree roots or damaged pipes, devising solutions that save you time, money, and stress.

These are definite signs that professional help is needed. Plumbers have the tools and expertise to diagnose and fix sewer backups effectively.

When in doubt, don’t risk it. Call a professional plumber and ensure your plumbing is in capable hands.
