Signs Your Septic Tank Needs Maintenance

How to Tell if Your Septic Tank Needs Maintenance

Your septic tank plays a crucial role in managing your home's wastewater. When it's taken care of, it operates quietly in the background, efficiently handling waste and keeping your living environment safe and sanitary. But just like any other system in your home, your septic tank needs regular upkeep to keep it in top shape. If you let problems slide, you risk facing costly repairs, environmental issues, or even a complete system breakdown.


In this blog post, I want to share some of the most common signs that your septic tank needs a little TLC and why it's so important to be proactive about it.


1. Unpleasant Odors Around Your Home 

If you start noticing a strong, unpleasant smell—think sewage or rotten eggs—around your yard, near the drain field, or even inside your house, that’s your first clue that something’s off with your septic tank. It might be full, overflowing, or have a blockage somewhere in the system. Don’t ignore that smell; it’s a key signal that you need to get in touch with a plumbing expert. Taking action now can save you from much bigger—and more expensive—problems later on.


2. Slow Draining Sinks, Toilets, or Tubs 

Have you noticed that your sinks, toilets, or tubs are draining slower than usual? That’s definitely something to pay attention to. It might be a sign that your septic tank needs some attention. When solid waste and sludge build up, it can block the flow of wastewater, which is not good news. If you let this slide, you could end up facing a complete clog or an even worse backup down the line.


3. Pooling Water or Wet Spots in Your Yard 

If you see standing water or wet spots in your yard, especially close to the drain field, that could be a big red flag that something's off with your septic tank. A properly functioning system should effectively filter and direct wastewater into the soil. When you start seeing wastewater rise to the surface, it could mean that your tank is either overloaded, leaking, or just not working right. This is concerning, not just because it can mess up your yard, but it can also lead to groundwater contamination, which can affect both your family’s health and the environment.


4. Gurgling Sounds in Drains or Toilets 

Have you ever noticed gurgling or bubbling noises coming from your drains or toilets? If so, this could mean that your septic tank is either backed up or facing a blockage. These sounds arise when air bubbles get trapped in the plumbing, often due to a clog or a full septic tank. It’s a pretty clear signal that something's off with your septic system, and it’s best to tackle it right away to prevent any further headaches.


5. Sewage Backup in Your Home  

Experiencing sewage backup in your home is definitely one of the most alarming and unsanitary indicators that your septic tank needs some serious attention. If you start to see wastewater backing up into your sinks, toilets, or tubs, it’s a huge sign that your septic tank is either full or not working as it should. This is an urgent situation that demands immediate action from a professional. Ignoring it could lead to major health risks and quite a hefty cleanup and repair bill.


6. Lush, Green Grass Over the Septic Tank Area  

While a beautiful, green lawn might generally seem appealing, if you notice that the grass over your septic tank or drain field is overly lush, it could indicate underlying issues. This usually happens because wastewater is leaking out and giving the soil an extra boost of nutrients, allowing the vegetation to flourish in that spot. So, while it might look lovely, it’s actually a warning sign that your septic tank isn’t functioning correctly and needs some care.


7. Regular Septic Tank Pumping  

It's generally a good idea to have your septic tank pumped every 3 to 5 years, depending on how big it is and how many people live in your home. But if you find yourself having to pump it more often, that might be a red flag. It could mean your tank is a bit too small for your family, or there might be something else going on that's preventing it from doing its job properly.


Why Keeping Up with Septic Tank Maintenance Matters  

Staying on top of your septic tank maintenance can really help avoid many of these issues. By booking regular inspections and pumping, you’re helping your system run smoothly, which can save you from costly repairs and headaches down the line. Plus, maintaining your septic system is great for the environment. Just think—untreated wastewater can seep into the soil and groundwater, posing serious health risks for everyone. So, let’s make sure your septic system is in tip-top shape!



When to Reach Out for Help

When you're gearing up for a long-overdue vacation, the last thing on your mind should be plumbing problems back home. Whether you're escaping the Tennessee heat or heading out for the holidays, safeguarding your home's plumbing before you leave can help you avoid leaks, bursts, and high water bills. At TLH Plumbing, we want every Tennessee homeowner to return to a problem-free home, so we’ve put together this essential vacation plumbing checklist. Why Plumbing Prep Matters Before You Leave Even a few days away can give minor plumbing issues the opportunity to escalate. Dripping faucets, frozen pipes (in winter), or water heater malfunctions can become costly disasters if left unchecked. A quick plumbing prep not only protects your home but also gives you peace of mind while you’re away. 1. Shut Off the Main Water Supply This is the most effective way to prevent leaks or flooding while you’re gone. If a pipe bursts or a valve fails, having the water turned off can make the difference between a damp floor and thousands of dollars in water damage. How-to : Locate your home’s main water valve—usually near the water meter or where the main line enters your house. Turn it clockwise until it’s fully closed. 2. Drain and Flush Once the water is off, turn on your faucets and flush your toilets to drain the remaining water in the lines. This is especially important during winter months when pipes can freeze. Bonus Tip : Pour a small amount of plumbing-safe antifreeze into toilets and drains if you expect freezing temperatures. 3. Adjust or Turn Off the Water Heater If you’re gone for more than a few days, your water heater doesn’t need to work full-time. Tank Water Heater : Turn it off or switch it to “Vacation Mode” to conserve energy. Tankless Water Heater : Most units have a vacation setting or can be turned off entirely. 4. Check for Leaks Before You Go Inspect faucets, toilets, and under-sink pipes for any signs of drips or leaks. Even a slow leak can cause damage or spike your water bill over time. Not sure what to look for? TLH Plumbing offers fast, affordable leak inspections in the greater Tennessee area. 5. Clean and Clear Drains Pour a little baking soda and vinegar down your kitchen and bathroom drains to help eliminate odors while you’re gone. Run your garbage disposal with cold water to clear any leftover debris. Don’t forget : Empty the dishwasher and washing machine and leave them slightly open to prevent mold and mildew buildup. 6. Inspect and Secure Outdoor Fixtures Tennessee weather can be unpredictable. Before heading out: Disconnect and drain garden hoses. Check outdoor spigots for leaks. Consider using faucet covers in the winter. 7. Let Someone Know If a trusted neighbor or friend is watching your home, let them know how to reach your plumber in case of emergency. TLH Plumbing provides prompt, local service across Tennessee—and we’re just a call away.
