Septic System Problems That Can Mimic Drain Clogs

If youre experiencing water pooling in your yard or any bad odors near your septic tank, it might be possible that your septic tank drain pipe is clogged. Here are some problems that can show symptoms similar to drain clogs.

  1. Clogged Outlet Pipe Baffle

Your main septic tank mainly has two sources for wastewater drainage: an outlet pipe baffle and an inlet baffle. The outlet baffle keeps the solid material and sludge from traveling down to the leach field. These solid materials can cause a clogged leach field if they enter the leach field.

If any baffle outlet or inlet is clogged, it can prevent wastewater from draining completely and slow the drains. You cant clear these types of clogs on your own; you need a professional septic service contractor to clear the clogs.

  • High Level Of Water In Septic Tank

If you notice that your full septic tank has water above the normal operating level, you may have a clogged leach field or drain pipe.

The solid materials used in your everyday routines can cause blockages and slow drains if placed in the sink, garbage disposal, toilet, or shower. To avoid drainage problems, check that the toilet paper youre using is septic-friendly, and dont put anything that cant break down easily in the septic tank or nature into the drains.

The sewer pipe in your septic tank is the main septic tank drain field transporting grey water from the house to the septic tank. If you have planted trees near your septic tank, the tree roots can block the sewer line. Some other factors such as earth movement caused by heavy equipment and earthquakes can also cause damage to the main sewer pipe. You need to hire a septic professional to determine if there is a problem with your sewer pipeline.

Your septic tank has a limited lifespan, but some property owners do not realize this. The leach field, an integral part of a septic tank, can last for one to two decades based on where it lies and how much water you consume.

Drain line failure occurs due to backups getting into the main septic line or too much solid material, sludge, or grease clogging up into the drain pipe. Driving heavy vehicles, cars, or trucks over the leach field can cause Drainfield failure. If the leach field of the septic tank is damaged, it will not be able to process hot water or cold water for that matter from the septic tank. This will lead to slower drains and eventually an overflow in the septic tank itself.

Wearing gloves while unclogging the septic tank can save you from harmful bacteria and getting hurt when handling the auger. Plug the mechanical drill into the closest outlet and switch the button to the forward position. Be sure not to start the drill when the cutting blade is outside the pipe, as it can run violently.

Continue forcing the drill into the pipeline until the septic tank clogs break apart and the water moves through the septic tank pipe normally.

If the clog is removed, the water flow will start from the pipe even when you have to drill inside it. But if you cannot unclog the pipe with the current mechanical auger, try another one of a longer size that can reach deeper inside the septic tank pipe.
