Common Septic System Myths You Need to Know
On February 16, 2025 By newsroom Topic: Home Services
Avoid septic disasters by debunking these widespread myths about maintenance and care.
1. Myth: A Well-Maintained Septic Tank Never Needs Replacement
- Reality: Even with proper care, a septic tank will eventually need replacing, typically after 20–30 years. Poor maintenance can shorten its lifespan to as little as 5 years.
2. Myth: Additives Eliminate the Need for Pump-Outs
- Reality: Additives may interfere with solids settling and harm tank walls. Regular pump-outs every 2–3 years are critical for preventing backups and expensive repairs.
3. Myth: A Full Tank Always Needs Pumping
- Reality: Septic tanks always appear "full" because they hold liquid waste. Pump-outs are only needed when solid waste fills about one-third of the tank, as determined by a professional sludge test.
4. Myth: Repairs Are Cheaper Than Pump-Outs
- Reality: Skipping a $200–$500 pump-out could result in a $1,700+ repair bill—or even a $6,000 tank replacement. Regular maintenance is far more cost-effective.
5. Myth: Clogged Systems Can’t Be Repaired
- Reality: Many clogs can be cleared using high-pressure water jetting, but only a professional can safely and effectively handle this. DIY fixes risk damaging pipes and contaminating groundwater.
6. Myth: Seeding Your Tank Is Beneficial
- Reality: Adding yeast, manure, or dead animals to "seed" a tank is unnecessary. Normal waste already introduces the beneficial bacteria needed for a healthy system.
7. Myth: Anything Can Be Flushed
- Reality: Only wastewater, sewage, and toilet paper should go down the drain. Items like grease, coffee grounds, feminine products, and even harsh cleaners can cause blockages and harm microbial balance.
8. Myth: Building on Top of the Septic Tank Is Fine
- Reality: Structures like patios or sheds can block access to the tank and hinder soil oxygenation, leading to system failure. Opt for lawns or non-aggressive plants over the tank area instead.
9. Myth: Professional Maintenance Isn’t Necessary
- Reality: Annual or biannual professional inspections are crucial. Specialists monitor waste levels, perform pump-outs, and address potential issues before they escalate.
Pro Tip: Stick with expert advice and routine maintenance to extend your septic system’s lifespan and avoid costly headaches.
