5 Common Causes of Blockage in the Sewage System

Dealing with a sewage blockage is one of those unpleasant realities that no homeowner wants to face. But understanding the common causes can help prevent these issues before they become major headaches. Let’s dive into the five most common causes of sewage system blockages and how you can keep your pipes flowing smoothly.

Cause 1: Fat, Oil, and Grease (FOG)

Fat, oil, and grease, often referred to as FOG, are major culprits in causing blockages. These substances typically enter the sewage system through kitchen sinks. When hot, they may seem harmless, but as they cool, they solidify, sticking to the walls of pipes and narrowing the passage.

How FOG Enters the Sewage System

Every time you wash a greasy pan or rinse off an oily plate, FOG makes its way down the drain. Even if you run hot water or use soap, these greasy substances don’t simply disappear. Instead, they accumulate over time.

The Impact of FOG on Pipes

As FOG builds up, it creates a sticky, wax-like substance that clings to the inner surfaces of pipes. This buildup can severely restrict water flow and eventually lead to complete blockages.

Prevention Tips

To prevent FOG-related blockages, always scrape food scraps into the trash before washing dishes. Consider installing a grease trap to catch FOG before it enters the sewage system. Additionally, periodically flush your pipes with hot water mixed with a little dish soap to help break down any grease accumulation.

Cause 2: Hair

Hair is another common cause of blockages, particularly in bathroom drains. While a few strands might not seem problematic, hair can quickly form tangled clumps that trap other debris.

Why Hair is Problematic

Hair tends to bind together and latch onto other substances within the pipes, creating large clumps that can be difficult to remove. This is particularly prevalent in sinks and showers.

Areas Most Affected by Hair Blockages

Bathrooms are the most affected areas. Shower drains, in particular, are notorious for hair blockages, but bathroom sinks can also fall victim to this issue.

Effective Prevention Methods

Using a drain cover or hair catcher in showers and sinks can significantly reduce the amount of hair that enters your plumbing. Regularly cleaning these covers will ensure they remain effective.

Cause 3: Foreign Objects

Foreign objects can be a big problem for sewage systems. Items that shouldn’t be flushed or washed down the drain often find their way into the sewage system, causing significant blockages.

Common Foreign Objects Found in Sewage

Wet wipes, sanitary products, paper towels, and even small toys are frequently discovered during pipe inspections. These items do not break down like toilet paper and can easily cause blockages.

How These Objects Cause Blockages

When these objects enter the sewage system, they can get stuck in narrow pipes or at bends in the plumbing, leading to significant obstructions. Their inability to dissolve exacerbates the problem.

Proper Disposal Practices

To avoid blockages from foreign objects, only flush human waste and toilet paper. Dispose of wet wipes, sanitary products, and other non-dissolvable items in the trash. Educate family members, especially children, about what can and cannot be flushed.

Cause 4: Tree Roots

Tree roots seeking moisture can infiltrate sewage systems, causing major blockages. This issue is particularly prevalent in older homes with mature trees nearby.

How Tree Roots Invade Sewage Systems

Tree roots are naturally drawn to the water and nutrients found in sewage pipes. If there are any small cracks or joints in the pipes, roots can penetrate and grow inside, causing blockages and even breaking the pipes over time.

Signs of Tree Root Blockages

Signs of tree root invasion include slow drains, gurgling noises from toilets, and unusually lush patches of grass in your yard. These symptoms suggest that roots might be obstructing your sewage system.

Solutions and Preventative Measures

If you suspect tree roots are the issue, consult a professional plumber who can use specialized equipment to inspect and clear the pipes. Preventative measures include regular maintenance and potentially removing or relocating problematic trees.

Cause 5: Structural Issues

Structural issues within the sewage system can also lead to blockages. These problems often stem from aging infrastructure, poor installation, or ground movement.

Types of Structural Problems

Common structural problems include collapsed pipes, misaligned pipe joints, and sagging sections of piping. These issues can obstruct the normal flow of wastewater, leading to blockages.

How Structural Issues Cause Blockages

When pipes collapse or joints become misaligned, it disrupts the smooth flow of wastewater, causing it to back up and create blockages. Ground movement or settling can also cause pipes to sag, creating low points where debris accumulates.

Repair and Maintenance Tips

Regular inspections can identify structural issues before they become severe. If you live in an older home, consider having your pipes inspected by a professional. Repairing or replacing damaged sections promptly can prevent major blockages.

The Consequences of Ignoring Sewage Blockages

Ignoring sewage blockages can have severe consequences, impacting your health, property, and wallet.

Health Risks

Sewage backups can expose you and your family to harmful bacteria and pathogens, posing serious health risks.

Property Damage

Untreated blockages can lead to sewage spills, damaging floors, walls, and personal property. The cleaning procedure is frequently expensive and time-consuming.

Financial Costs

The longer a blockage is ignored, the more expensive it becomes to fix. Early intervention can save you a significant amount of money.

How to Identify a Sewage Blockage Early

Early detection of sewage blockages can prevent major problems. Knowing what to look for can save you from a messy and expensive situation.

Common Symptoms of Blockages

Slow draining sinks, toilets that don’t flush properly, and unpleasant odors are common signs of a blockage. Your drains may possibly be making gurgling noises..

DIY Detection Methods

Using a plunger or a drain snake can help you determine if a blockage is minor. It's time to hire an expert if these techniques fail.

When to Call a Professional

If DIY methods fail or if you notice multiple slow drains in your home, it’s best to consult a professional plumber. They have the tools and expertise to identify and fix the problem efficiently.

Prevention Tips for Homeowners

Preventing sewage blockages involves regular maintenance and smart disposal habits.

Routine Maintenance Practices

Regularly clean your drains using safe, non-corrosive cleaners. Schedule annual inspections with a professional plumber to catch potential issues early.

Smart Disposal Habits

Take care what you flush down the toilet and don't pour grease down the drain. Educate your family on proper disposal practices to prevent foreign objects from causing blockages.

Regular Inspections

Inspections on a regular basis might spot any faults before they become serious ones. This is particularly important in older homes with aging plumbing systems.

Professional Help: When and Why

Sometimes, professional help is necessary to tackle severe blockages or ongoing issues.

Situations Requiring Professional Intervention

Persistent blockages, sewage backups, and suspected structural issues warrant a call to a professional plumber. They possess the knowledge and tools necessary to identify and resolve complicated issues.

Benefits of Professional Services

Professional plumbers can provide thorough inspections, accurate diagnoses, and effective repairs. They can also offer advice on preventing future blockages.

Choosing the Right Plumber

Look for licensed, insured plumbers with good reviews. Ask for recommendations from friends and family, and get multiple quotes to ensure you’re getting a fair price.

DIY Solutions for Minor Blockages
