Septic Tank Cleaners questions, answered by experts

We’ve explained how deep-rooted plants can damage a septic tank from the outside, but plenty of things can ruin it from the inside, too. For example, flushing bulky items (like paper towels, diapers, and wipes) can clog your septic tank. Cooking oil, grease, and household chemicals can also harm your system. And since a new septic system costs between $3,460 and $11,450, it’s worth following these guidelines.

Running water may get rid of a sulfur smell temporarily, but it isn’t a long-term solution. If your taps smell like sulfur, take a look at some of the potential causes we’ve outlined above. Depending on what’s going on, you might need to contact a pro to identify and fix the issue.

Watch for slow drainage, pooling water in the yard, or unpleasant odors inside or outside. Addressing these issues timely avoids significant disruptions or costs.

Using less toilet paper is the easiest way to prevent future clogs. Also, avoid flushing sanitary products, thick paper towels, or hair down the toilet. If you’ve been using a brick in the tank to reduce the water used to flush the toilet, take it out immediately. Bricks will eventually fall apart and clog your toilet drain. Keeping your toilet lid closed also helps avoid future clogs.

Some flushable wipes companies say they are designed to disintegrate within a few hours to a few days after being flushed. These wipes allegedly use materials that are more water-soluble than traditional wipes. However, many experts have raised concerns that even so-called "flushable" wipes do not break down as easily as claimed and can contribute to clogs and blockages in sewer systems.

To prevent plumbing and sewer problems, avoid flushing wipes, even those labeled as flushable. Instead, dispose of them in the trash. This can help prevent costly plumbing issues and reduce the strain on wastewater treatment systems.
