8 Warning Signs Of Septic Tank Trouble

Here are some signs that your tank needs immediate attention -

1. Foul Odor

A persistent, sewage-like smell around your home or yard is often the first sign that your septic tank needs immediate attention. These odors often indicate that gases or untreated waste are leaking from the system, either due to a clog, a full tank, or cracks in the system.

While it may be tempting to mask these odors with fresheners or outdoor sprays, it’s important to realize that the odor is a signal of something drastic. A lingering smell can also travel to your home through sinks, making it unbearable to live in.

2. Pooling Water

If you notice puddles of water in the yard that seem unexplainable, that’s a warning sign that the septic tank is malfunctioning. When a tank overflows, the wastewater can rise to the surface, containing harmful bacteria and contaminants that harm the plants and trees around the drain field.

Additionally, this excess surface water can erode the soil around your drain field and also deteriorate structures, such as patios and walkways. Moreover, it can increase pest problems, as insects and rodents are mostly attracted to moist areas.

3. Sewage Backup

Sewage backup mostly occurs when the septic system is at or beyond its capacity. This happens when the tank hasn’t been pumped in years. Raw sewage contains harmful pathogens, which can lead to serious health issues and costly repairs.

Apart from health concerns, backups can damage your home’s plumbing system. Pipes can be corroded and or blocked over time, and may lead to increased pressure that shortens the appliance’s lifespan.

4. Slow Drains

If your tubs and sinks aren’t draining as they should, the problem could be a localized clog in a drain. Though there are other reasons for these issues, they mostly occur when the septic tank reaches its capacity. This prevents the wastewater from draining and causes backflow into your home.

Slow drains across multiple fixtures often indicate a septic issue rather than a one-off clog. It can cause long-term stress on the plumbing network, which often results in pipe leaks or bursts. Using chemicals or plungers may offer short-term relief, but it does more harm than good.

5. Gurgling Noises

Hearing a strange gurgling sound coming out of the pipes, sinks, or toilets? This mostly indicates that air might be trapped or that some pipe has been clogged. However, if you hear this noise from multiple drains, understand that the problem is your septic tank.

A gurgling sound means water and waste aren’t moving efficiently through the pipes. This can strain the system, lead to unexpected pressure buildup, and eventually harm the plumbing system.

6. High Nitrate Bacterial Level In Well Water

Septic tanks are supposed to isolate waste from the environment. However, cracks, overflows, or a saturated drain field can cause untreated water to seep into any nearby water source, contaminating it. Cooking or drinking this water can lead to severe health issues, especially if you have kids and elderly people at home.

In addition to health dangers, contaminated water can also damage appliances, such as washing machines, dishwashers, water heaters, etc.

7. Alarm Activation (Modern Systems)

Many modern septic tanks are equipped with alarms that monitor high water levels, pump failure, or blocked discharge lines. When the alarm activates - usually with a light or audible signal - it means your system may be overflowing or has failed.

An activated alarm allows you to take immediate action before the situation worsens. Ignoring it can result in extensive plumbing damage, including septic pump burnout, full system backups, and even flooding in the basement.

8. Lush Green Grass Over Drain Field

If you notice a green patch of thicker grass in your lawn, it could indicate a septic system leak. When the untreated septic water leaks out of the system, it acts as a fertilizer that helps grow grasses all over the drain field.

Though the lush green grass may look pretty, it is a sign you shouldn’t ignore. This is because they mask the underlying issue. Over time, excessive moisture in the soil can compromise your home’s foundation or underground utilities. The worst part is that it can attract underground roots that can cause and worsen the blockage.

What Are The Potential Causes Of Septic Tank Emergencies?

Here are some major causes of septic tank emergencies -

Excessive Water Usage

A septic system is designed to handle a specific volume of wastewater. When the limit is reached, the tank does not have enough space to separate solids from liquids properly. This forces partially treated wastewater into the drain field, which increases the risk of overflow and system failure.

Tree Root Intrusion

Tree roots naturally seek out moisture and nutrients and can enter the septic tanks. Fine root systems can infiltrate through small openings and expand, which restricts the flow and causes the pipe to collapse and the septic tank wall to rupture. Sometimes, these issues occur without warning signs!

Flushing Non-Biodegradable Items

Septic tanks break down only organic waste, not non-biodegradable items, such as plastic, synthetic wipes, or feminine hygiene products. When these items are flushed, they accumulate in the tank and pipes instead of decomposing. This interferes with the natural bacterial breakdown process and may also cause pump malfunctions.

Damaged Or Aging Septic Components

Septic tanks are made of baffles, tanks, pipes, and filters, which may degrade over time due to corrosion, shifting soil, or normal wear and tear. As they age, these components fail or are compromised. This means they become prone to sudden failure, leading to inefficient functioning and costly repairs or replacements.

Irregular Maintenance

When the waste starts building up in the tank, its capacity and efficiency are reduced. This may cause the septic tank to force the wastewater into the drain field, where it clogs soil pores and disrupts proper drainage. If you leave the tank neglected, it is more likely to harbor harmful gases and bacteria that can compromise human health and the environment.

What To Do If You Notice These Signs?

Here is some expert advice on what you should do if you notice septic tank emergency signals -

Avoid DIYs

It might be intriguing to investigate or fix a septic tank on your own, but that’s not a good idea. Inspecting or repairing a septic tank requires professional knowledge and expertise, which you, as a homeowner, may lack understanding of safety protocols. This makes the problem worse and leads to injury, contamination, or further damage to the system.

Stop Water Usage (Immediately)

The moment you hear the drain gurgling or notice backup or standing water, stop all water use in the house. Turn off faucets, halt laundry loads, and avoid flushing toilets. This helps prevent additional overflow or backup while you wait for professional help.

Keep People And Pets Away

During a septic failure, contaminated wastewater may surface in the yard. The wastewater contains bacteria, parasites, viruses, and other harmful pathogens that can cause illness. Hence, keeping children and pets away from affected areas helps avoid any accidental exposure.

Call A Professional Service Provider

Fixing a septic tank needs licensed plumbers. They inspect and fix the issue safely while adhering to local regulations. They ensure that the system is pumped, cleaned, repaired, and disinfected properly.

How Can You Prevent A Septic Tank Malfunction?

Preventing a septic tank malfunction is important to ensure it is in optimal condition.

Scheduled Regular Pumping And Cleaning

Based on the size of your household and the number of people living in it, a septic tank should be pumped and cleaned every 3-5 years. It prevents solid waste from accumulating and causing blockages or backups.

It is advisable to call in a professional for inspection, as they can spot early signs of issues that might turn into an emergency.

Use Water Wisely

Every drop of water that goes down your sink and bathtub ends up in the septic system. It is recommended to spread out your laundry loads, fix leaks immediately, and consider installing water-efficient fixtures.

Running several water-heavy appliances at once, taking long showers, or ignoring a leaky tap can overwhelm the system, causing it to overflow.

Be Mindful Of What You Flush

Flushing wipes, even the ones labeled as “flushable,” shouldn’t be flushed down the toilet. In addition, avoid flushing diapers, paper towels, etc., down the toilet, as it can clog the system and cause serious problems.

Also, never pour oil, grease, paint, or harsh chemicals down the drain - they can disrupt the natural bacteria that break down waste. It is advisable to stick to only septic-safe products and be alert to what you or your family might be sending down into the system.

Protect Your Drain Field

It is crucial to keep your drain field safe, as it helps filter and disperse treated wastewater. To keep it working, avoid driving over it and building structures on top of it, as it can crush the underground pipes. Also, ensure not to plant deep-rooted trees anywhere near it, as their roots can invade the plumbing system.

In addition, make sure rainwater from downspouts or landscaping doesn’t flow into the area and oversaturate it. This makes the soil, which leaves no room for wastewater to disperse.

Keep Track Of Your System’s History

It’s wise to keep a record of every pumping service, repair, inspection, upgrade, etc. This helps you stay updated on your maintenance schedule. Also, having a detailed report can increase your property’s value.

A clear history also helps professionals assess what’s been done - and what’s likely needed. It’s a small habit that can save you time, stress, and unnecessary costs later.
