Septic Tanks questions, answered by experts

To prevent septic tank problems, save on repair costs, and keep your home running smoothly, it's essential to perform regular maintenance. Have your septic system inspected by a professional every one to three years, or annually if possible, to spot potential issues before they develop. You should also have your tank pumped every three to five years, or more frequently if recommended by a professional based on your household's usage. Additionally, be mindful of what goes into your system. Avoid flushing items like paper towels, wet wipes, and feminine hygiene products. Do not dispose of other inappropriate substances, and try to avoid excessive water usage at a single time.

Your drain field or leach field should be 1 to 3 feet under the ground. It will be a little shallower than the septic tank, although it can be the same depth or slightly deeper. The proper depth of the septic tank is up to 4 feet. It’s possible that your local regulatory agency requires a certain depth for your drain field.

A septic system can fail for various reasons, and most commonly, excessive water use or sudden surges in wastewater can overwhelm the system's capacity. Neglecting regular maintenance, like tank pumping and inspections, can also lead to clogs, leaks, and eventual breakdowns. Other issues that lead to failure include age-related wear and tear, root infiltration, improper disposal of non-biodegradable materials or chemicals into the system, unsuitable soil conditions, physical damage, and even environmental factors like flooding or soil erosion.

Getting well water tested costs $100 to $350 if done by a pro. You can also buy DIY test kits for $20 to $100, but professional tests are more reliable. You can get a comprehensive well inspection, which includes advanced water testing, for $700 to $750, which you should do yearly anyway.

Yes, septic tank companies must be licensed in most states and municipalities to perform services like installation, alteration, repair, and pumping. Since laws vary by location, it's crucial to check local requirements.

Hiring an unlicensed professional can lead to poor work, code violations, and significant fines. Always verify that your chosen company is properly licensed and fully insured to avoid liability. You can use tools like Angi’s contractor licensing search to check a pro's credentials.

It's also helpful to understand the difference between licensing and certification. A license is a legal requirement to operate, while certifications are voluntary. Credentials like the “Angi Approved” badge indicate that a business meets extra standards, such as passing a background check and maintaining a high rating.
