Septic Tank Repair questions, answered by experts

With proper maintenance, leach fields’ and drain fields’ life expectancy is up to 50 years. However, poor soil conditions, heavy usage, and improper maintenance could cause either type of field to have a far shorter lifespan of 15 to 20 years. Having your drain field and septic tank inspected every five years should extend the system’s lifespan.

While mound septic systems can provide cost-effective wastewater treatment in many instances, they do come at a significant initial installation cost and require a lot of space on your property for the mound and its replacement field. The installation cost is so high because this is a project that requires an exceptional level of skills and expertise to execute properly.

Most homeowners know there’s a septic system problem when they can smell one. However, this isn’t exactly a scientific deduction method. Consider some of the other signs: standing water or constantly damp earth in the drainage area, toilets and sinks that won’t drain or frequently back up, and loud plumbing. You really need to be on top of routine maintenance with septic systems in order to avoid such unpleasant symptoms of a septic issue. 

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.

The depth of a septic tank’s drain lines is between 18 and 36 inches underground. These pipes are filled with perforations and surrounded by sand, gravel, or a combination of both, as both materials help filter wastewater. While some pipes are buried closer to the surface, this can create problems unless the soil is compact and doesn’t shift much.
