The Real Cost of Ignoring Your Septic System
According to the US EPA, more than one in five American households depend on a septic system. Most homeowners give it almost no thought — until something breaks.
- Average septic repair: $627 – $3,040 (Angi, 2026)
- Drain field replacement: $5,000 – $20,000
- Full system replacement: $8,500 – $25,000+ (Angi, 2026)
Consistent maintenance — pump-outs every 3–5 years and basic monthly care — costs a fraction of that. SepticFormula shows you exactly what to do and when.
