Smelly Yard? How to Tell If Your Septic Tank Is the Cause

A foul smell emanating from your drains and the backyard often indicates a severe underlying plumbing problem that requires immediate attention. While there are many possible causes, such as full dumpsters or decaying foliage in the fall, your wastewater treatment system may be the culprit. As a trusted septic company, Rooter Man Plumbing can inspect, detect, diagnose, and recommend the best course of action to restore comfort and functionality. With all the different causes of unpleasant odors, accurate diagnosis is crucial to ensure early septic tank repairs before the damage gets out of hand. If you are unsure whether the stench in your property is caused by a failing septic unit, here are the signs that indicate your waste system is the cause.

Rotten Egg-Like Odor

Foul smells range from funky or moldy to decay, and identifying the type of smell on your property can help you make the right decision. If you smell a rotten egg-like odor near the septic tank installation site, then chances are it is the problem. Over time, wastewater from your home collects in the storage tank, accumulating toxic gases that resemble sulfur or rotten eggs. While unusual smells may not raise concerns initially, ignoring odors from the septic tank or drain field can cause devastating damage. The best way to avoid such scenarios is to hire a trusted technician for routine maintenance, ensuring minor issues don’t escalate into sewer smells and overflows.

Visible Signs in Your Yard

Besides sulfurous smells, visible signs like unusually lush greenery and soggy patches near the septic tank installation area are red flags. A leaky or overflowing tank can allow raw sewage to seep into the soil, providing vital nutrients and water for plants to grow. Although it is every homeowner's dream to have a lush yard, greener grass near the drain field requires immediate attention. Additionally, puddles of effluent or soggy patches indicate system failure and risk environmental hazards. If you notice a foul smell in your backyard, walk around to check for visible signs before the damage worsens.

Slow Drains

A smelly yard may draw your attention to outdoor spaces, but the impact can be indoors. This is particularly true for septic-related issues, which manifest as slow drains in your home. Once you notice slow-draining tubs, sinks, or toilets, inspect the drain field for visible signs of damage and foul odors. In the case of minor clogs, plunging and snaking can restore water flow and functionality to your home. However, recurring or persistent clogs indicate a septic problem that requires immediate attention. Professional septic tank pumping and maintenance can keep your waste system in top shape, preventing slow drains, backups, and other nasty surprises.

What to Do Next

Now that you know the telltale signs that usually accompany a smelly yard, familiarizing yourself with the steps to take is crucial.

Call a Septic Company

If you notice any of the signs mentioned, it is crucial to call a professional quickly. A highly trained technician utilizes specialized tools and extensive expertise to pinpoint the cause, assess the damage, and recommend long-lasting solutions. Even if DIY enthusiasts can tackle minor repairs, septic tank pumping and maintenance should be left to professionals.

Do Not Flush Improper Items

Septic systems are designed to handle toilet paper and human waste. However, homeowners dispose of different items that may not be septic-friendly. Some of these non-biodegradable materials include wet wipes, diapers, and hygiene products, which clog the system and cause severe damage. With that said, ensuring you dispose of organic waste and scheduling routine septic tank cleaning can enhance functionality and durability.
